Title: Just a power question
Post by: Smokey Eddy on September 30, 2009, 10:22:54 am
Is this normal voltage to be reading at the battery?

battery light is OFF
running lights (no head lights) and nothing else - 11.89v
lights, stereo - 11.73v
lights, stereo, defrost, heater blower - 11.57v
car off ignition off - 12.12v

That was yesterday after a 15 minute drive

Now after a 15 minute drive my battery light is ON/flickering and i put my multimeter to the battery with stereo & lights on and it read 14.33v...

You have a bad voltage regulator.. are they built in to the alt's? I think they are. New Alternator I think Ed... :(

seems normal to me. After a drive leave it sit before your test about an hour or turn your headlights on for a couple seconds to get the static charge off of it, then test and I bet it will be in range...or you'll know if she is junk.

car off ignition off - 12.12v

That is the only non-running value.
If they all seem normal why is my battery light on/flickering. It's never solid. It's always a flicker, sometimes MUCH brighter than other times.
Sometimes when i open the door my light in the roof will pulsate.
You can replace the V-regulator i thought Jer?

Sounds like the regulator is dying, on its way out rather than already flatlined.

As I recall, the regulator and brushes are a single replaceable unit, and fairly easy to acquire.

Upgrade your grounds while you are at it.  The Voltage Regulator is cheap and should be in-stock just about anywhere.

Run a good ground from one of the case bolts on the alternator, and another one from one of the bolts on the valve cover.
