Question about Cars & Trucks

Open Question

I connected my battery wrong. I did not start the car I knew what I did as soon as I did it. When I corrected the problem I noticed I blew out the radio, so I changed the fuse. My charging light came on so I replaced my alternator. I started my car but my battery still won't hold a charge and the car shuts off within a few minutes. Is there another fuse I blew that prevents the alternator from charging the battery.

SOURCE: Charging problem.. Wont charge battery

The instructions for installing a new alternator usually read to fully charge the battery (12.3 - 12.8 volt range). Otherwise, the alternator will be damaged when it initializes. I have seen some extreme damage result from installing a new alternator with a low-charge battery. The torque required to turn an alternator when damaged in this scenario is unbelieveable!

SOURCE: battery charge light comes on a few minutes after car starts

Couple of things to check, first this may be nothing more than a belt that has loosened or stretched after the install.There should only be about a quarter of an inch stretch in the belt between pulleys. Caution - only check with engine stopped!!! The alternator causes a strong resistance when it is producing electric power, so slippage is to be checked first. Second, if the battery light comes on and off; it maybe acting in error. Get a multi-meter and check the battery voltage with car and ignition shut off. With the meter set on 12volt bat, place the black probe on the negative side of battery or ground and the red probe on the positive side of battery. If you get a reading of 12.66 v the battery is being charged and is full. If you get 12.45 you have a 50% charged battery. If less the alternator wiring needs further checking into as there maybe issues with wiring or the alternator itself. Hope this helps.

the relay should not have any power to it. i would think there is a sort some were on the ignition. i would check the ignition wiring and make sure its not damaged or assembled wrong. relay should only get power when the key is in ignition and turned to start engine.

I left a mirror light on overnight without noticing. it discharged the battery to the point of almost not starting in the morning. but it did start and run just fine. I had to re set the clock though. ...


I was told about that and what I remember is this:....The history that the car's computer has stored to keep your car running properly is lost when the battery goes dead....then when the battery is charged the computer has to gain back all that data to properly tune your car. Suposidly it takes 30 starts and drives to regain enough data to get back where you were.
Some are not sure that's true but I believe it.

How you manage to drive to work if the car did not start after replacing the 100A fuse? I'm confused. You may want to check the 15A fuse for the computer inside the car and check the rest in the same area for possible damage.

The reason why the battery blew up is because of a deffective alternator. The charging regulator on the alternator has malfuntioned, and caused the battery to be overcharged. The reason why your car wont start is because overvoltage has damaged some of the electronic sisytem in the car associated with the ignition system.
