Question about Hyundai Motor 2003 XG350

Open Question

Electrical failure My alternator was putting out about 16V (I know that now) and fried a new battery...when I jump started it all systems went wild - wipers came on, trunk popped, lights flashed, turn signals came on, etc. Now after replacing the battery and alternator most of the electrical systems are still down - the windows, lights, radio, heater, AC...none of it works. The car starts, runs and the fuses look good so how do I get the electrical systems working again? Many thanks,

SOURCE: i jump start my wifes car at night with the cables backwards

I found that while checking my fuses that i had pulled out what looked like a black plastic "fuse puller" that was actually some kind of jumper. I had accidentally re-installed it reversed. I reversed it back to its original position and all lights, clock, radio, etc.. work normal now.

SOURCE: 2003 Hyundai Elantra alternator will not charge

If you have replaced the alternator and the battery has been checked and showed to be in good working condition then the only thing left is either a bad fusable link or cable (negative or psitive) going from battery to engine. You should inspect these cables and there connections. Corrosion on these connections can cause these problems. You also mention that the alternator will not keep car running. It should when you disconnect the negative battery cable while the engine is running.If all connections and cables are good and you haven't replaced alternator then you should do so.

RECENTLY HAD MY CAR JUMPED BECAUSE I LEFT THE HEADLIGHTS ON. NOW MY RADIO ISN'T WORKING. DID I FRY THE RADIO AND COULD A REPLACEMENT RADIO FIX THIS OR COULD THIS ALSO BE AFFECTED BY THE WIRING?


When jumping, or anything else electrical on a vehicle, always connect negative LAST. You could have fried the fuse or the radio. Check fuse first. On newer vehicles jumping is dangerous and can cause system failure.

It sounds like you have a wire directly connected from the battery to the starter motor by passing your ignition switch. double check that the new harness that you put in with the new alternator is correctly installed. hope this helps good luck.

Vehicle was parked and not started for 2 months.


Hi, there will be diodes in the generator that are letting the power from the battery drain away through the parked times when not in use. to prove it charge the battery- then disconnect the negative terminal on the battery, connect 24 hours later and see if the battery as kept it charge, if so - fit new alternator, good luck.

2003 Honda Accord. Dies when I try to put it in drive


you are having a problem with your alternator. the battery has a main purpose to start the vehicle, keep computer memory, and give power to electrical components when the key is in the on position. the alternator charges the battery and gives power to electrical components when the vehicle is running. now when you hit the brakes there was an extra load added to the alternator and if the car died then the alternator is running very weak and needs to be relace.

Gauges jump w/ acceleration & batt/charging light on


First, have the battery charged and load tested. If it does not pass load test, replace it. An alternator is not made to charge a battery. it's job is to maintain the current state of charge. By driving and attempting to charge it that way you over-worked the alternator and may have damaged it or the regulator. Once the battery is fully charged and in good condition, you will need to check the charging system for proper operation. If the gauge system does not return to normal, it will need further diagnosis to correct it.This isn't a "cure" but rather, what you need to do in order to get back to "square one". With the alternator running "flat out" trying to charge a dead battery it can put out over 15volts, possibly damaging the dash/body control module or computer.
