Question about Cars & Trucks

1 Answer

Battery will jump, not hold charge. While driving, cd player and radio come on and off by itself. Also other electrical issues like the electric seat and door locks are intermittantly acting up.

I can charge the battery and it will start, but not hold a charge consistently. Also I can turn the radio on while driving and it will intermittently go off and on by itself. I turned the radio off, and I could hear the CD player trying to engage without me trying to start it.

Electrical problem in cars can be a real bear to troubleshoot. Suggestions are a leak to ground draining the battery. Bad battery a possibility but this wouldn't explain the other problems. Check that you have good grounds and connections. This kind of problem can have pros scratching their heads but a good one might zero right in on the problem.

Try "clearing the cache" by removing the negative battery cable for a few minutes. Before doing so, be sure you know how to reset the clock and radio codes & presets.

What happens when my car won't hold a charge


It can be either voltage regulator, alternator or the battery is not holding a charge. Start with the regulator first it is the cheapest. most parts houses will test your electrical system for free.

1998 Saturn SC2. For the last couple month sometimes my car won't start. I'll turn the key and get a whimper then nothing. If I then manually lock and unlock the car then it eventually starts. ...


There are many problems that could cause this issue. Your electrical system might have a drain somewhere -- maybe your alarm is malfunctioning (if you have one), or maybe a wire in the engine has somehow become damaged, grounding the system and discharging your batter at a slow rate. If your battery has been completely discharged before (completely dead) it might not be holding a charge like it should. Your alternator might not be charging the batter like it should while you drive, causing your battery to drain constantly and never recharge automatically like it's supposed to. It could be something more complex in your car's computer or electrical system.
The easiest way to check this is to go to a mechanic with an electrical system checker. Sears Auto Canter has all of the equipment, and charges a reasonable rate for checking your electrical system. Their equipment checks, no only the battery, but the whole electrical system for power drains, and the effectiveness of your alternator. If there is a power drain, Sears Auto can find it -- and they can help replace what is broken. They can also check the health of your battery itself (if it is not holding a charge, you can get a new one there). If it is not that, at least you have eliminated one possible cause.
If the car will start when jumped, it is most likely an issue with which Sears can help. If the car is still not working when attached to another car's battery or a jumper battery, then the problem is a bit more serious. In this case, a professional mechanic can inspect the car and find the issue, or at least give you a cost estimate, so you know if it is worth fixing.

I jumped started my 2007 Torrent and now the radio wont come on, nor the sound for turn signals.


Not a solution, but our torrent is doing the same thing. Periodically things like the radio, blinkers, dash lights, etc won't work. After parking the car for a while and trying again they seem to work again. This continues for about 2 weeks then the car decides not to start. After recharging the battery; a couple of days later the cycle continues again.
We thought it might be a short in the DVD player as it happened when we left the disc in, but the dealership has been unable to duplicate the issue.
Everything from updating the software on the electric seats has been done without success.

Car starts when boosted but wont start by itself after tuning it off. Is it the battery or alternator?


It could be either. The alternator feeds electrical charge to the battery. Easiest way to tell is spend the 100 bucks and replace the battery. Even if your alternator is good, some batteries will not hold a charge even when boosted.

If that doesn't work try to get a used or rebuilt alternator.
Personally I would take it to a shop and have them check it first. You could have a solenoid issue and your battery and alternator are fine.
There could aslo be an electrical short in the wiring harness that is causing a draw on your battery.

My battery died now disc player says no discs please help?


Very tricky, my suggestion is to restart the radio again see if it reads the CDs this time. Try removing the radio fuse, where all the other fuses are at. Turn the radio on without the fuse, press and hold a button for a minute just to make sure you drain the electricity from the changer. Then put the fuse back and see what happens. You can also disconnect the negative or ground from the battery wait five minutes and connect it again but this will also restart the car computer.
