electrical: STUPID mistake, car wont start after jump

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.

Mar 14,  · Battery on my mower was dead so I jumped it off another battery hooked it up backwards on the external battery. Now it does nothing when i turn the switch. I tried hooking jumper cable to starter the starter turned but no spark.

When hooking up to jump my TJ I crossed the cables in the cars. Terminal sparked on contact, I said “hmmm – that seemed abnormal. Switched them and jumped the jeep no problem. No issues on good car. Got to my location in the jeep, and battery was dead. Got a jump from someone, and two possibilities occured jump did not work: Possibly didn’t work due to bad connection to terminals.

I can’t imagine this, but this is the only possibility I can imagine 2. A fuse was blown on mine and didn’t allow a jump. The Jeep did not appear to gain anything from the jump – just clicked and didn’t turn over. That guy trying to jump me wished me luck and took off. Another guy walked by and I thought I’d try again. This time, the difference being that I switched a fuse – my “Starter” fuse – I grabbed a 40a fuse from next door to it and switched the two.

Jumper cable mistake may be costly

Exactly how the diodes will react to the excessive current flow is hard to predict. Sometimes they blow apart into an open circuit or a very high resistance, sometimes they melt together into a short circuit with a varying amount of resistance but generally quite low. In the course of working with solid state rectifiers since I was about nine years old, I have seen many different failures as a result of excessive current.

I don’t think you can predict the results. At least I have not seen pattern. The best result would be to hope for an open circuit, as this will tend to stop the current flow.

Apr 14,  · The jumper cables begin to smoke within seconds of a complete contact. This is the final stage of electrical issues that I have been having. I replaced the .

Where does the Yes, I think that is exactly it. The cars see their battery’s voltage, but the jumper cables see twice the voltage, hence the smoke and pending doom. The light-bulb picture is excellent. From the original problem, I have two updates. First, the problem about the car not holding an idle, and stalling, there is no answer. I could not start the car.

Contact Kelly How to hook up booster cables? The most important thing to remember is that the black on the dead car gets hooked up to something metal rather than the battery. If it is hooked up incorrectly, the computer could be blown or if the battery was frozen then it could explode. Here is the step by step process. First, make sure everything is turned off! Connect the other end of the positive cable to the good battery.

It could cause the battery to explode if enough hydrogen gas is present from it or destroy the diodes in the alternator of the car or both cars if that is what is connected to the other end of the jumper cables for the power source and not just a lone “Jumper Battery”. I have seen it happen, this is not a guess.

So there, I said it. Going to drop my pride and admit it. I got into a rush and hooked up the car battery backwards. Im doing an engine install, and needed to drain the fuel from the lines, so I grabbed my trusty Optima red top, set her o n the frame like the battery normally sits in my car and proceed to hook up the battery in reverse polarity. Check the fuses up front under the clam, nothing out of the ordinary. I hook up the battery correctly and all the lights, blinkers, alarm, immobilizer, everything seems to work fine.

I go to start the car and its kind of cracking and popping and making weird noises I have the straight pipe and muffler off so I chalk it up to not having a good enough connection on the terminals. I snug the cables onto the battery terminals and go to re-start. After my second attempt she starts right up. For not having the exhaust connected nor the O2 sensors she seemed to run ok. Just had a high idle to start with, followed by a fluctuating idle, then a steady idle.

I blipped the throttle a few times and she seemed responsive as well.

Take care when jump-starting your battery, or pay the price

Friday, March 22nd, AT Most of those links are four to six inches long. If you measured on two points between the ends the break could be outside of those points. The wire can burn open in any area. It would be more accurate to put one meter probe on the positive battery cable, then probe the regular wire just beyond where it was spliced to the fuse link. What you did was severe overkill.

Dec 24,  · hooking up the cables the wrong way can lead back into the computer and blow it : Resolved.

I can’t believe I’ve been on the road going on 7 years without jumper cables.

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.

So yeah, the cables got hooked up wrong because I saw black cable and assumed that was negative and didn’t check the markings on the battery itself since I didn’t have a flashlight at the time.

Connect the other end of the positive cable to the good battery. Connect the negative cable (black)(-) to the negative post of the good battery. Connect the negative cable to a metal part of the dead vehicles engine. Do not attach the negative cable to the negative post. Get in your vehicle and start it up.

Any connection of a battery with the polarity reversed will just about always cause damage to the diodes in the outboard motor charging system. My inference from reading the description that the terminal posts of the battery melted is that the amount of current flow was very high and was allowed to continue for a prolonged period. Based on this I would guess that the diode failure eventually resulted in the diodes blowing into open circuit. However, before that happened there could have been high current flow through other portions of the charging circuit, including the windings of the alternator coils.

Your problems are most certainly in the alternator diodes. The stator coil may also be damaged from over current and over heating. After that it is harder to predict what else may have been damaged. At the moment of connection the forward biased diodes in the alternator were conducting, and they more or less protected other elements of the circuitry. But when they blew to an open state, current could easily flow via other paths. It is an unfortunate circumstance that connection of the battery with the polarity reversed can cause so much damage.

This is one of the reasons I recommend careful color coding of the cables and the battery terminals to prevent such errors. The insulation could have melted and you could have a dangerous situation. This is probably not the cause of your problems but considering the battery terminals melted there was some serious heating along the current path.

GMC 2001 Sonoma Owner’s Manual

Your car suffered damage. The extent of this damage is presently unknown and may either be obvious to diagnostics or remain hidden for some time to come. The details of this damage should be unimportant to you save for getting a total repair and reasonable assurance that you’ll be safe and have a reliable vehicle into the future. It matters not one bit that there be a fuse here or there that might be damaged, or a resistor pack

Mar 09,  · The only way any damage can occur to either is from hooking the cables up backwards. Now you can damage a car by disconnecting a battery and reconnecting it with out any sort of voltage or current supply so you don’t spike the cars computer when the battery is reconnected.

Many of us do padlock the trailer hitch lever down so it can not be disconnected from the ball. This can also be a good thing to get used to doing as it is a reminder to not forget to snap the lever down onto the ball. But what about securing the hitch extension into the bumper’s receiver? If you just use the original spring snap clip to hold the pin in place, it is rather easy to pull the pin, slide the trailer rearward enough to get the extension out of the receiver and then transfer the extension to a waiting vehicle that has the same commonly used receiver.

To prevent this, I have drilled my extension pin out enough to also accept a padlock bail, as shown in the photo below on the right. It is nice to purchase 2 or 3 padlocks using the same key for this situation. You do need to remove the extension padlock occasionally and clean the padlock up so it will function when needed. I have found that if you don’t, the lock may become hard to unlock.

Therefore it may be prudent to smear some Vaseline around where the bail enters the base to keep out water which turns metal into rust and over the key slot to keep the dust from getting inside the tumbler. For those of you who may wonder what the upper license plate frame says, it is “Crime Control” on top, and the bottom as seen, “Not Gun Control”.

Padlock securing the extension to the receiver Don’t overlook padlocking your spare tire to the trailer as shown below.

Every morning Reggie, Roger and I set out in the direction of the mountains. We walk up our desert boulevard to Midland Road. A dirt road takes us in a loop back to Midland Road and we return to camp. When the road deteriorates, I park and we disembark. Reg and Rog can hardly wait for me to latch their leashes and place them on the ground. As we go along I note the condition of the road.

The charge and discharge cycle of a battery causes hydrogen gases to build up. These gases escape through vented cell caps and can accumulate around the battery. If you connect the jumper cables incorrectly, you can create a much large spark than normal and this spark can ignite these gases and cause an explosion.

Ok , Well I stand corrected Learn something new every day like I’ve been doing this wrong for years. Failure to do this may result in burned circuit breaker contacts, a run-down battery and possible serious damage to the generator itself. The procedure is to use a jumper wire and connect one end to the Armature ‘A’ post of the generator; then touch the other end of the jumper wire to any ‘hot’ wire or terminal.

Do not prolong the connection after the flash has occurred. It is recommended that this be done before connecting any wires to the regulator. Julie Don’t worry about the technicalities Julie. The point is getting the job done. I personally don’t agree with the Motors Manual. I always polarized a generator by quickly pulsing the field with a jumper from the battery. As previously posted by redpanhead, the process is to create some residual magnetism in the fields by applying a DC current momentarily in the field windings.

I can’t imagine why anyone would want to apply the current to the Armature terminal, because in order for the fielsd to get any residual magnetism from that would be a secondary transfer and no where nearly as effective as directly exciting the field windings. Surprisingly, many of them never needed it. One thing people should take particular care to do is polarize using the ungrounded terminal of the battery.
