280Z Turbo Posted July 20, 2007 Share Posted July 20, 2007 I recently swapped over to a Z31 alternator. My first one died suddenly, so I'm wondering if I have the wiring wrong. My Charge light is on constantly, but my voltage is steady. I used these instructions: http://www.zcarcreations.com/howto/voltreg.htm 5 to 1 3 to 6 But Blue's is different: http://atlanticz.ca/zclub/techtips/alternatorswap/index.html 5 to 1 3 to 2 Which is better?

Challenger Posted August 9, 2010 Share Posted August 9, 2010 (edited) Bump! Quick question, it says the 78 alternator is 60amp, ZX alternator is 70amps but is it (78's) internally regulated? It appears the 78 and on alternators all work for this swap? Is there any benefit to keep the 81 turbo alternator on my turbo motor on my 78 Z or should I just swap it out for the one originally on my 78? Thanks Edited August 9, 2010 by Challenger Quote Link to comment Share on other sites More sharing options...
