Question about Cars & Trucks
Power light comes on but will not charge battery. Another charger worked and charged battery. Why will charger #85-435 not work?

He said his battery charger is not working, this has nothing to do with the car not starting or charging? So if anyone can recomend what he needs to do to get his battery charger working would be helpful to him.

SOURCE: battery not charging
Sounds like the cells in the battery have shorted. It's probably shot. Does the car run once its jump started? Does it continue to run after the cables are removed, if so your alternator is ok and its the battery. Hope that helps.

I don't know if your car has an integrated regulator or not; some house the regulator in a section of the alternator case, others mount it remote from it.
The regulator monitors the load and battery voltag,e primitively but effectively, and controls the current flowing through the field winding of the alternator to ground, changing the magnetic field intensity and consequently the voltage output of the alternator.
The 'hot' end of the field is internally connected to the + output, the 'cold' end is controlled by a transistor inside the regulator which, in turn, is controlled by circuitry monitoring the system voltage.
Some alternators can be tested by sticking a wire through a specified opening, actually shorting the controlled end of the field to ground briefly, while monitoring the voltage across the battery, doing this though for seconds only.
This essentially bypasses a suspected defective regulator; this causes the output voltage to rise instantly to its maximum of ~17 volts if the alternator is OK.
I don't recommend poking a wire at random into an available opening so having a service manual (Haynes-Chilton) would be nearly mandatory.

the two problems that you posted could be connected somehow by the alternator not charging because of the belt issue. so if you have a low battery, the cigarette lighter would have a low voltage also.
then on the ipod issue, the memory of the radio could have been lost due to removal of battery cables or the battery really went down on its voltage. just re-configure your radio to accept the ipod music.
tnx 4 using fixya,

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!
