you have a dead short in the wireing.
Your battery and alternator need attention. It sounds as if the charging is faulty and your battery has degraded.
No, you must have a charged battery for the alternator to work.Here's an explanation of how the charging system works:http://www.ricksfreeautorepairadvice.com/repair-topics/alternator-generator/testing-an-alternator-without-blowing-it-sky-high
Perhaps an alternator test is in order. Typically, when the motor is running, the car gets it electricity from the alternator, not the battery. (At least that's the way it used to be, someone correct me if I'm wrong)
well if you really hooked up jumper cables wrong and you got by the fireworks show then you probably damaged your alternator and battery. Possibly blowing fuseable link,but if car runs then alternator and battery.
Try blowing graphite down there.
Have your alternator checked quickly - before your battery dies and it messes up your entire system. Happened to me recently, and I replaced alternator finally, but ended up blowing a bunch of fuses it looks like. Now the car won't start at all. Still trying to figure it out.
you most likely have a loose or unattached ground wire to some major component.
I am no mechanic, however this is a 2 part fix. First the battery is shot, so replacing this is one part. The next is a little more complicated. You should take your vehicle to autozone or somwhere similar and get the alternator checked out. It sounds like this may need replacing as well. Like I said start with the battery, as this is the cheapest, but get the alternator checked out as well, or you would just waste the money on blowing another battery if the alternator is the problem. Best of luck!
Hi, I had this problem on a 2000 Alero. Had to disconnect the battery to shut it up. G.M. replaced the horn relay to aleviate the problem. Duke
You may want to check to see if the transmission line that runs underneath your battery is pinched. We recently had the same experience, and it was determined that when the battery was replaced, the transmission line was pinched because it sits directly underneath the battery.
The voltage regulator is built into the alternator. If you have used your vehicle to jump start another vehicle, even if it is the first time your auto has been started since the alternator was replace you risk blowing the new alternator. Always make sure that when connecting jumper cables that the red is connected to the positive of both autos and the black is connected to any metallic ground on the engine NOT the negative of the your battery. When the dead engine starts and the alternator fields are flashed in the dead car it causes a voltage spike that will eventually blow a good alternator. You might get by with it many times, but the law of averages will catch up with. Not IF but WHEN! Once you start you auto use a voltage tester and touch the battery cable ends, not the battery posts. You should get a reading of 13 volts or more. If not either the battery is defective or there is a short somewhere else. If you do not have a voltage tester just start the engine and disconnect one lead from the battery. If the engine dies the alternator is bad. A good battery should read no less than 10.89volts when fully discharged. If it reads less the battery is defective. A fully charged good battery should read 12.5 volts or slightly more.
In the 1988 Nissan the alternator, instrument panel, and backup lights shared a fuse. Before changing a fuse see if the backup lights work (have someone watch when you are in reverse). If the neutral start/backup light switch is broken internally, it can be blowing the fuse when you put the car in reverse.
