cockerstar Posted March 4, 2008 Share Posted March 4, 2008 Well guys, I ran a quick search and I didn't some across anything so I figured that I could get come conformation here real quick Is the alternator off of a '77 280z compatible with a '79 280zx? I don't see why it wouldn't be because they are coming off of the same engine, but I wanted to double check. My zx has a shot alternator and I just ordered one from autozone yesterday. Today I found a member here that has a freshly rebuilt one with about an hour of run time on it before the engine was torn down to be parted for sale. If things work I'd love to save some cash and help a fellow Z'er out at the same time Quote Link to comment Share on other sites More sharing options...
zcarnut Posted March 4, 2008 Share Posted March 4, 2008 Is the alternator off of a '77 280z compatible with a '79 280zx? No. The 1970-77 alternators used an external voltage regulator. The '78 and up alternators had the regulator built into the alternator, i.e., they were internally regulated. Quote Link to comment Share on other sites More sharing options...
