mars23z Posted July 7, 2006 Share #1 Posted July 7, 2006 I was wondering if the alt from the zx is the best upgrade for a 260z. I can buy a 60 amp from advance auto that is made for the 260z but was wondering if that is the biggest or best for my mostly stock 260zThanks Chris Link to comment Share on other sites More sharing options...

HOWEVER, all alternators for Z cars 78 and later are internally regulated. That means you will need to bypass your external regulator or face some big-time issues with your charging system. You'll also need to install a diode on the alternator to prevent feedback issues that will cause run-onBeen there.Done that.Got the T-shirt.

Could be wrong though... Link to comment Share on other sites More sharing options...

Could be wrong though...You could also be right. I don't know what causes the issue. I don't think that it's because of the presence/absence of an electronic ignition. I have a Crane electronic ignition in my 240 and experienced the run-on.Anyway, the diode is cheap. It's handy to have in case run-on is an issue.

mars23z Posted July 7, 2006 Author Share #7 Posted July 7, 2006 What about a 50 or 60amp alt is that better than stock? Link to comment Share on other sites More sharing options...

Clean your switch, connectors, and bulb sockets.Another solution might be to change out the flasher unit if you haven't done that. Link to comment Share on other sites More sharing options...
mars23z Posted July 7, 2006 Author Share #12 Posted July 7, 2006 That looks awsome but for $199 i think I'll go with a 50 amp for $30 Link to comment Share on other sites More sharing options...
