260z Alternator issue

Recommended Posts

The battery I had when I got the car was fried. So I went and bought a new one and started the car, then when I tried to shut off the car nothing happened. I talked to a buddy and he said it's probably cause it's internally regulated. Now I have to keep jumping the car and I think and I think the issue is  frying the new battery too. And each time I shut the car off I have to pull the coil wire. I've looked into how to wire it but can't find any sure answer for a 260z. Any info helps! And if more info is needed on my end let me know! Thanks everyone!

watch this about 45 secs in to this vid for the HOW TO.


ON 510s I heard of the external voltage regulator is bad causing the vehicle to not shutt off.

I assume the 260z is a external reg type alternator.

YOu can go to Rockauto.com and look up the part and see a photo of it. Key is the lettering on the T connector.


I would start the car , run then turn key off and pull the reg connector.

I would also do the drain test before and after to see if battery is draining.


soemtimes a bad diide can cause a drain to and putll the + output wire on alternator and see if the test light goes out.
