charging light

[Chamse]

Hey everyone

 

On my datsun 620 1976, the charge lights comes on, when i turn on the lights, and shut off when i turn the lights off...

I am unsure if replacing it with a replacement 35a alternator will fix this, or i should try to upgrade it to a better one? or could it be some other problem?

 

Kind regards

Well you could try measuring the voltage across the terminals...

 

12.6 engine off

over 14 when running

 

Turn lights on should still be 14 may drop slightly.

 

 

Check the plastic plug in the back is firmly seated and in place.

Check the plastic plug for the voltage regulator is firmly connected.

Battery posts and cables clean and tight.

Or take it out and bring it to AutoZone or prolly and get it checked.

I didn't know. I thought this was visible to all.

 

 

Maybe the brushes are worn down too much. I've pulled brushes out of an old alternator and swapped them into another before.

 

One of the three diodes  may be bad or become un-soldered.  The output would be much less.
