Thread: too many volts

Sounds like a stuffed regulator. Usually inside the alternator disguised as the brush-holder.

Then again, LandRover electrical systems are very sensitive to defective earthing.

Your batteries are not long for this world running at 19+ volt.

Since it's a 1984 model, I reckon you're overdue a new alternator anyway. Probably around $550, hopefully less...
I vaguely recall folk on here saying that certain BOSCH (Falcon?) alternators can be made to fit.

thanks superquag i have a near new spare ready to bolt straight on, i just needed to know so i dont blow the spare up. i will also undo and clean up all the earths i can find. thanks from peter

RAVE manual -on disc is your friend, buried in it I've seen a location guide for every earth-point.
Available from the Forum.

On a car this old it never hurts to add a few extra earths, (he wrote, not having gotten around to doing it himself yet).

Agree... on any Land rover...
Was chatting to a Pommy-trained mechanic recently, and he said the same thing. Corrosion on each and every earthing point is the leading cause of most LR's electrical woes.

I've run a 25 mm² cable from alternator mount to NEG battery post.

make sure your alternator warning light is functioning correctly, in early setups it provides the power for the excitation and the bulb is the limiter.
if its shorted the alternator will make too many volts.
