1975 XJ12C,, no charge lite came on.

test volts at battery, 11.9volts,1200rpm.

what to look for 1st and ETC.

seems as tho its always somthing! DARN, car.

 

ronbros, does the car have an internal or external regulator for the alternator/generator? I am not familar with the specifics of the car you mention, but I know enough about how the power is generated in vehicles to help out. If in doubt, an internally controlled alternator will have a single wire coming off (running to the battery or electrically equivolent point via a large gauge wire) of the alternator vice an externally regulated one will have multiple wires coming off of it where most of the wires are small gauge wires with a single large gauge wire.
