HB280ZT Posted October 13, 2005 Share Posted October 13, 2005 Hi All, Well I did a search and did not find what I was looking for so here goes. I need to find the setup or adapter to attach the 10si alt to my 82 ZXT motor. In another post they mentioned a bracket but not where to get it?? Also what do I do to upgrade the 77 280Z wiring to work with the internally regulated alternator. Thanks for your help. HB280ZT Quote Link to comment Share on other sites More sharing options...
yo2001 Posted October 13, 2005 Share Posted October 13, 2005 GM one wire only needs the battery wire connected to the back of the alternator. 3 wire needs one battery positive plus, constant 12v and ignition 12v inline with charge light.

HizAndHerz Posted October 14, 2005 Share Posted October 14, 2005 Edit: I completely rewrote my lengthy post with pictures of the AC-Delco alternator swap that we did to all three of our 280Z's, so I moved the guts to a new thread.

HB280ZT Posted October 14, 2005 Author Share Posted October 14, 2005 HizAndHerz, Thanks for the information, that was what I was looking for. Now I just need to get finished with the autocross season and then it will be time to start taking things apart and fixing them. Thanks again.

Workinprogress Posted October 26, 2005 Share Posted October 26, 2005 HizAndHerz, All of your pictures died, where can we find them? Quote Link to comment Share on other sites More sharing options...
Workinprogress Posted November 3, 2005 Share Posted November 3, 2005 Hmmm, the pictures are not there when I try at work, but here at home. Nevermind the idiot with the overactive firewall at work........ Quote Link to comment Share on other sites More sharing options...
Guest alanq64 Posted January 24, 2006 Share Posted January 24, 2006 did you document the wiring part of the install yet? Quote Link to comment Share on other sites More sharing options...
HB280ZT Posted February 2, 2006 Author Share Posted February 2, 2006 HizandHerz, The wiring part would really help. I am up to my *** in winter fix items and if you could give us a detailed write up of how you did the wiring that would be great. Thanks for the help.

David K Posted June 7, 2006 Share Posted June 7, 2006 Very cool Hiz. I just lost another alternator tonight. This is my 2nd in 1 year. I know its my stereo because both times the alternators went out, it was at night with all lights on in heavy traffic on the hwy with my stereo pretty loud. I want to do the GM alternator. I wanna ask you, wouldnt it be easier to drill a smooth hole through the datsun alternator bracket and use a long bolt with a nut on the end instead of threading the hole? Again, thank you for the writeup. Its EXACTLY what i sat down to search for tonight. Quote Link to comment Share on other sites More sharing options...
trwebb26 Posted October 3, 2006 Share Posted October 3, 2006 I just did a GM 1-wire install this weekend. The writeup was very helpful... but the bolt you should use is an M10 X 75mm long (not 100mm like the post says). Quote Link to comment Share on other sites More sharing options...
HizAndHerz Posted October 5, 2006 Share Posted October 5, 2006 I'm about to do this on 280Z #4 tonight so I am just now coming back to read what I posted almost a year ago. I wanna ask you, wouldnt it be easier to drill a smooth hole through the datsun alternator bracket and use a long bolt with a nut on the end instead of threading the hole? I threaded the bracket so that the bolt would not wobble around. I suppose a nut could be used instead, but threading stills seems better to me. ... the bolt you should use is an M10 X 75mm long (not 100mm like the post says). No, I'm 100% sure it is M10 X 100mm. I'll try to take pictures of the electrical part this time around. Quote Link to comment Share on other sites More sharing options...
primer&rust Posted October 5, 2006 Share Posted October 5, 2006 Nice write up on using the z bracket for the GM alternator. If you didn't want to thread the inside of the Z mount you could probably drill it through and just use a nut, washer, and lock washer on the back side of the mount. I had a custom made mount through a welding shop. It's not perfect but it works and lets me use a chromed GM 100amp alternator. As for the one wire or three wire I like the three wire set up. It is detailed in the Jags That Run v8 swap book. On my 280z with the ammeter I only had to run two wires one to the stock postive that runs to the fusebox and one to the battery for the 12 voltage sensing (regulator). It is grounded through the alternator body. The three wire setup lets the ammeter show how many amps are charging. With the one wire you only see the negative draw the car is using. Very good cheap alternators. Quote Link to comment Share on other sites More sharing options...
