Contact Author Source Battery problems can strike without warning, the unsuspecting owner fearing that something terrible happened to their vehicle overnight and now it won’t start at all. More often than not though, the vehicle is completely fine other than a battery that’s acting up. Car batteries are probably the most volatile component in the car, and it doesn’t take much for them to go bad. They only have a shelf life of a few years, and they’ll die quicker because of things like disuse, corrosion, and faulty connections. It takes a very large amount of power to turn over an engine and start a car. The batteries are designed to give a big push of power and voltage for a short period of time. If you’re not sure what your problem is though, make sure you read through all of the possible problems, and go to my other articles on solenoid problems and alternator problems to make sure you can rule those out too. Types of Problems There are multiple types of problems that a person might run into with their battery. Here are just a few. Faulty Connection There are two ports or posts that stick up from your battery, the negatively charged post and the positively charged post.

You can either turn off the running auto before attaching the cables, or leave it running. Admin Edit — Correction Made From the comments area below: Connecting the black ground jumper cable of dead negative grounded vehicles to the sheet metal of the vehicle rather than the negative terminal is a very important safety feature.
A jump start, also called a boost, is a method of starting a vehicle with a discharged or dead battery.A temporary connection is made to the battery of another vehicle, or to some other external power source. The external supply of electricity recharges the disabled vehicle’s battery and provides some of the power needed to crank the engine.
The batteries need to be securely mounted to the frame of the cycle. This is typically done with a box shape or angle iron. You do also want to keep in mind that the batteries are the heaviest part of the motorcycle. Fortunately, that describes the big hole left by the removal of the engine and transmission.
The trick is to design a rack that fits in that space and holds the batteries. In the earliest, experimental version of the motorcycle, I played around with something as basic as a “tray” put across the bottom two frame members. Small batteries could just sit right on top of that in a single layer. The larger batteries could only fit two there, so the others would have to be mounted in some other way. I experimented with “unistrut” – a slotted C-channel material available at building supply stores.
It worked well in holding the batteries, but I didn’t like the looks. The batteries stuck out the sides a bit in a way I didn’t like.

I think the key to an explanation is that the cut out relay senses current direction as determined by referencing the magnetic field of the current to the magnetic field of a voltage fed electromagnet. Since both were reversed the cut out relay didn’t have a clue as to the polarity. I hope I explained my thinking clear enough.
If the high voltage flipper coil switch shorts what happens if you hook up jumper cables backwards the flipper lane change switch, the cable is long enough the keypad can easily be used outside of the game. Control Board, bold text are the keypad buttons.
Hardware Abuse Some of the things people do to computers is downright painful. Recently, I got a call from someone who turned off his computer whenever he found himself somewhere in Windows he didn’t want to be. Wonder of all wonders, scandisk found a score of lost allocation units and bad sectors. He called about a week later and said that it would no longer boot up. He brought it in, and I discovered that sixteen nicely drilled holes were in the bottom of the case.
I asked him about it, and he said the machine was too hot sitting on his lap, so he had drilled these “air holes. I once had a customer that wanted a light in her computer, similar to a computer she saw at one of her friend’s houses. So she lit a candle and set it inside her tower case. One of my favorite stories is from back in the 90s. A guy bought a bit sound card for his computer, but for whatever reason decided he only needed an 8-bit sound card.
Instead of taking it back and exchanging it, he figured all he needed to do was get a pair of scissors and physically cut the sound card in half. My friend from school thought that since the CPU heatsink burned his finger when the computer was on, it must be keeping the CPU too hot to overclock.

Article about batteries and car jumping (The complete and correct way to do it) Here I will give you the right and up to dated way to jump-start a car safely. Of course this is if you are stranded away from home. Also avoid connecting the cables backwards; very bad things can happen if you do.
Contact Author Source Most people have never heard of a solenoid, and when their vehicles start having electrical problems, they automatically assume that the battery or the starter is dead. Very possibly, it could have been the solenoid. A solenoid is just a coil of wire that’s wrapped around a hollow non-magnetic core. It receives an electric current from both the ignition switch as well as the battery.
The small electric current from the ignition switch forces the solenoid to clamp together a pair of heavy contacts. This allows the large electric current from the battery to flow to the starter and turn over the engine. Generally, when a solenoid is broken, the two metal clamps won’t operate anymore to complete the circuit, making it impossible for power to flow from the battery. Diagnosing a Problem If your car won’t start and you’ve changed your battery or jumped it, and if there’s no sound at all out of the starter when you turn the key, then it’s a good bet that your solenoid is bad.
Depending on the solenoid, you may or may not be able to test it. It’s job is simple: So when it’s broken, it no longer is able to connect the battery to the starter. So testing is just a matter of bridging the connection and allowing power to flow from the battery to the starter. If you have a metal tool with a rubber handle, you can touch both of the posts with the metal, thus bridging the connection and allowing power to flow.
Just be sure not to shock yourself.
My Jeeps Embarrassing to admit, but jumper cables got hooked up wrong, what to check. Please forgive me as this thread lacks the TJ part of TJ technical forum, but I feel like a dumb jerk for screwing this girls car up and I posted in the electrical forum but its usually pretty dead over there and I want to get her back on the road asap. Long story short was that I went to jump a friends car, it was dark and cold and we were in a hurry and I have never jumped a car with the BMW is I just bought as my DD last week.
STEP 8: Connect the other end of the red (positive) cable to the live car’s positive battery post. See Fig. 1, Step 2. STEP 9: Connect one end of the black (negative) cable to the live car’s negative battery post. Do not connect the other end of the negative cable to the dead car’s_battery post. See Fig. 1, Step 3.
This is a battery terminal puller. It cost a couple of bucks. The arms arrow go underneath the cable end clamp, and the center pushes against the terminal post on the battery. Turn the handle and the cable end clamp lifts right up. Then the battery cable can be pulled away. I’ve had a battery cable spring back and touch the battery terminal. I make an effort to tuck the cable away.
Can you fix a lead-acid battery that’s charged backwards?
Contact Author Learn how to jump start your car safely when jumping someone else’s battery, so that both your batteries come out alive! Source Jumping another person’s car without killing your own car’s battery is actually quite easy. With just a little bit of common sense, and the tips below, you’ll be jumping batteries like a pro in no time! Yes, but it was scary! This usually happens either because the jumper cables are too short or because one or both vehicle’s batteries are located in awkward locations in the engine compartment.
Regardless, if you’re unable to jump your friend’s battery without touching your car to theirs, then you’re going to risk killing your own battery.
“Question: If you want to charge a bad batter with a good one from another car can you just hook up the jumper cables and leave them for a while or do the cars need to .
Reply oscar on July 3, at 8: Reply lasersaber on July 3, at It might extend the life of your car battery. It would remove a large part of the cranking amps from the battery when starting the car. Looking through the Internet you can mostly observe watered down information, something like bla bla bla, but not here to my deep surprise. It makes me happy..!

“Can I use a car (battery) to jump my scooter?”
So, a co-worker needed a jump-start after leaving her lights on, and I thought I would be a good Samaritan and help her after work. Her car was parked on a busy road, and I had to pull up next to her in the opposing traffic lane to be able to reach her battery. In my haste, I put the positive and negative clamps on the wrong terminals on MY car hers were correctly attached. When I got in my car to start it, I could see that the wires were smoking. I immediately got out and disconnected the cables.
Make sure to carry a set of jumper cables in your car at all times, just in case. Any set will do the job, but look for cables gauge 4 to 6 in size, with a length of 10 to 20 feet.
Share this Willie Worthy The voice on the other end of the phone had that “upset sound” to it that you just knew that he had messed something up and was going to ask me to bail him out. It came out, “Willie, I think that I really screwed up! I was trying to jump-start my Jeep and hooked the battery connections backwards–like man, I got the negative to the positive and the positive to the negative.
It sparked a lot, but I thought that was just because one battery was dead and the other was charged, then I realized my mistake. What kind of damage did I do? I went on with the fact if he had done any damage, the easiest way to find out would be hook up the jumper cables correctly and try starting the Jeep. It started right up, so that was a good sign that the computer was not fried.
I had him disconnect the jumper cables and check the voltmeter to see if it was showing a charge. It was, so he got very lucky.
OT Neighbor hooked up jumper cables backwards
I drove to the store one day and when I got out of the store approx. No crank, no radio, could not use my remote lock the car. It’s like someone remove the battery while I was in the store. I open the hood and everything looks normal. The battery was there.
Jan 28, · – L Power Stroke Diesel – OT Neighbor hooked up jumper cables backwards – My neighbors Grandson accidentally hooked up the jumpers cables backward on one end. They were trying to jump a escort with another vehicle. The escort was the one with the dead battery. The side that was hooked up wrong was on the.
Taking care of your battery. The best way to prevent battery failures is by doing regular maintenance on the vehicle. When regular maintenance is done the battery should be one of the main items checked. They should clean terminals, top off the fluid if possible using only distilled water, do some tests on it, and of course test the charging system etc.
Even the best batteries will meet their maker sooner or later. They can “diehard” or die soft but they all die. The average life of most batteries is about 3 years, believe it or not. I have noticed a decline on the life of a battery lately. So if your battery is about that age, have it checked or just change it to have peace of mind specially if you’re making a long trip.
What to do if your battery is dead. In an emergency when a battery is dead, the first thing that comes to mind usually is to “jump” the car. Well I don’t recommend this. First of all this is a potentially dangerous action. Doing this can cause an explosion and actually kill you.
electrical: STUPID mistake, car wont start after jump
Submissions must be something you saw that was odd and out of the ordinary for your work setting. Only original content is acceptable. Do not post pictures taken by others.
On cheap jumper cables often the connections to the clips are poorly made and will heat up very quick when a large current flows. Better to throw them away and get a good gauge of jumper cables 25mm² or larger with strapped alligator clips which make good contact.
West Fleet Direct http: To begin the install loosen the cap on the radiator overfill to remove pressure from the system do this while the engine is cool. Cut the hose closest to the drivers side It does’nt really matter where, I did mine about 6 inches after the fire wall. Then holding the ‘shut off valve’ with the vaccume controller twards the pass side install the portion of the heater hose coming from the cab to the top left nipple on the ‘shut off valve’.
Install the portion of the heater hose coming from the engine to the top right nipple and tighten the clamp. Next cut the heater hose closest to the pass side in the same location as the previous. Install the portion coming from the cab on the lower left nipple, tighten the clamp. Now install the portion going to the engine on the lower right and tighten the clamp. It sounds more complicated than it is. Once you do it it will seem real simple.
