Silas Cruse Posted February 21, 2018 Share Posted February 21, 2018 So last week my stock alternator died. I replaced it with my GM 1 wire alternator 60 amp , which i keep for just this type of circumstance. Since the tension bolt does not match up. I installed it with my Redneck wood shims method of tightness. Then on Monday i was able to get an JY alternator from a 2002 EJ25, $17.50 Below are the wiring diagrams I used. Now with everything on still have 14.1 at battery. Link to comment Share on other sites More sharing options...
skishop69 Posted February 21, 2018 Share Posted February 21, 2018 Good upgrade. One piece of advice: Get rid of the scotch locks and attach the wires correctly. Solder them and use heat shrink tubing or use shrink type but connectors. Scotch locks are hinky at best, ruin wires, provide a poor connection for loaded circuits and let in moisture which leads to corrosion and electrical Gremlins. This is not meant to offend, but inform. If you want a little more info, I did a lengthy write up on electrical here: http://www.ultimatesubaru.org/forum/topic/159953-wiring-dos-and-donts-a-guide/ 1 Link to comment Share on other sites More sharing options...
GeneralDisorder Posted February 22, 2018 Share Posted February 22, 2018 (edited) Easier upgrade - 86 to 94 Nissan Maxima. Direct bolt in. 90 Amp. Scotch loc's make me cringe. No bueno under the hood. Do it right with some heat shrink at least. GD Edited February 22, 2018 by GeneralDisorder 1 Link to comment Share on other sites More sharing options...
idosubaru Posted February 22, 2018 Share Posted February 22, 2018 Easier upgrade - 86 to 94 Nissan Maxima. Direct bolt in. 90 Amp. What about them being expensive OEM, low grade aftermarket, and 25+ years old used? 1 Link to comment Share on other sites More sharing options...
Subasaurus Posted February 22, 2018 Share Posted February 22, 2018 Easier upgrade - 86 to 94 Nissan Maxima. Direct bolt in. 90 Amp. i've heard of this upgrade before, but always wondered why its such an easy bolt in upgrade, is the reason because of the remnants of Datsun and Subaru sharing parts with one another in the 70's? and continued to carry some same parts though the late 80's? or just a huge coincidence?

Silas Cruse Posted February 23, 2018 Author Share Posted February 23, 2018 the EJ alternators are mostly 90 amp, and a direct bolt in. just have to swap pulleys, and connect the electrical. and yes i will make those connection heat shrink.

You're car has somewhat of an odd duck AC/Alt setup. Many EA82 car and EA81 are different. I am not sure that EJ alt would fit in the with an inboard alt setup. Not saying it won't but I feel like if it was truly an easy fix everyone here would have been on it 10 years ago. Link to comment Share on other sites More sharing options...
DaveT Posted February 23, 2018 Share Posted February 23, 2018 My understanding is that there were 2 different ac systems. The more common I came across is with the alternator outside, close to the battery. I've considered the upgrade, but I would have to do the rest correctly, and upgrade the output wire and fusible link. 1 Link to comment Share on other sites More sharing options...

Correct. to my observation and opinions, having own both kinds, the one with the A/C in the center and the alternator on the outside closest to the battery looked like it was Subaru Factory done, while the one with the alternator in the center and the A/C closest to the battery was professionally rigged on, probably done at the dealer at a customers request to have this vehicle but originally didn't have A/C. i honestly prefer the alternator in the center since any generic A/C compressor fits it, and they are really simple and on their own wiring diagram, although tightening the belt is just sticking a pole between the 2 components and eyeballing it. heres the 2 examples below 1989 GL 1994 Loyale Edited February 23, 2018 by Subasaurus Link to comment Share on other sites More sharing options...
GeneralDisorder Posted February 24, 2018 Share Posted February 24, 2018 EJ is not a direct bolt in. Maxima alts are direct bolt in. Just swap the pulley. GD Link to comment Share on other sites More sharing options...
Silas Cruse Posted February 27, 2018 Author Share Posted February 27, 2018 I made up the heat shrink wires for the 2002+ EJ to EA plug. Link to comment Share on other sites More sharing options...
