To polarize or not.
Posted by: Tom Turbo ()

Like many owners who don't drive their cars every day, I disconnect the battery to prevent parasitic drainage. Does this mean I have to repolarize the voltage regulator every time I restart the car? I haven't been doing it and don't get a generator light but I'm not sure this is significant. Opinions?

If it don't go, chrome it!

Shouldn't make any difference. The power to the generator is off whether the battery is connected or not. The generator frame retains "residual" magnetism once it has been polarized and that magnetism stays in place for a long time.

That sounds good! As I mentioned I don't get a gen light but I wasn't sure that was significant. Generator output and battery charging are two different things. I have had some mixed luck not unhooking the battery. If I didn't unhook it sometimes things would be fine a week later and sometimes the battery would be stone dead. I have put a meter on the battery and I get a 1.2 volt leak. The only way I can think of is to systematicly pull fuses until I find the offending circuit

Tom:

Pull the bulb from the glove box light, and see what happens.

Al,

That was the first thing I thought of too. The minor drain I'm getting, I think, can be found by popping out the fuses. The problem is I'm 6'4" and 280 so I have to remove the seat to get under the dash, but I'll have to do it anyway to put in the dash.

If it don't go, chrome it!

Should the generator lose its polarization the BATT light would come on and the battery will not charge. As stated by others, it takes more than a bit of time to have elapsed before polarization is lost.

"1.2 volt leak"
Please explain.

I'm guessing 1.2 A or 1.2 mA.

How about the heater tubing rubbing the starter until it wears through to the wire coil in the tube. Jim
