Charging issues

[mr928]

So my 1970 521 is showing 18 volts at the battery all of a sudden. Actually what got my attention was the smell of the battery cooking itself. The voltage regulator looks like brand new. Is there a way to test them?

Getting 18 volts at the battery is a voltage regulator test.

 

It failed.

 

Check the grounds, between the voltage regulator and the alternator frame before you condemn the voltage regulator.

I go with the solid state ones now myself plus they are cheaper.

 

The old Jap ones were adjustable but i never figured it out. I alwasy had spare regs.

 

 

all I can say if it says Made in USA(mechanical) on it its a Echlin brand sold thru Napa and they suck. They dont last long at all. 2 years for me

 

The Wells USA solid state one sold thru Carquests and others is OK. I use them

Ok I bought the Wells unit from Autozone ( $29.99) and that fixed the problem.

 

Thanks guys
