Airrun2002 Posted September 7, 2009 Share Posted September 7, 2009 I swapped mine out for the Quest 120 amp alt, There is substantially more modification you have to do to the alt before install but i think 88 did a write up on it. Link to comment Share on other sites More sharing options...
PATHRIDER Posted November 3, 2009 Share Posted November 3, 2009 Autolite 14661 @ O'Reilly Just installed it; 95 amps & dropped right in (after swapping belt pulleys) and now headlights are much brighter. does it have a lifetime warranty Link to comment Share on other sites More sharing options...

Well actually if you modify the bracket and make a small mounting bolt spacer, then there is no modification required on the alternator Link to comment Share on other sites More sharing options...
PATHRIDER Posted November 4, 2009 Share Posted November 4, 2009 Well actually if you modify the bracket and make a small mounting bolt spacer, then there is no modification required on the alternator Im lost here...isnt it that the alternator has to be grounded off on the top 2 holes where the long bolt goes thru to fit the factory bracket? and the bottom mount holes where you mount the other bracket with adjuster has to be grounded too?

RedPath88 Posted November 4, 2009 Share Posted November 4, 2009 I'll have to find the pics of my install or take new ones.. and review how I did it Link to comment Share on other sites More sharing options...
PATHRIDER Posted November 4, 2009 Share Posted November 4, 2009 I'll have to find the pics of my install or take new ones.. and review how I did it awesosme....Id really like to have a bigger alty but after looking at that other post seems that there has to be a lot of grinding on the alty (voids the warranty too)..I dont mind doing it once but how if the alty fails and id have to grind the replacement again...I was thinking on thaT MOD why not grind the bracket on top and make it narrower to accomodate the narrower top mounts on those quest alty. but anyhow your install is better if theres no mod that has to be done on the alty Link to comment Share on other sites More sharing options...

headpeace Posted November 4, 2009 Share Posted November 4, 2009 why did 88 run new cable to the battery? Link to comment Share on other sites More sharing options...
Kingman Posted November 4, 2009 Share Posted November 4, 2009 Probably less resistance, better connections, preventative maintenance, etc... Link to comment Share on other sites More sharing options...
ahardb0dy Posted May 12, 2010 Share Posted May 12, 2010 (edited) I recently swapped the 60 amp alternator in my 90 sentra with a 110 amp alternator out of a 95 -97 Maxima, the alternator in the maxima's come in 110 or 125 amp outputs, I did have to make a small bracket due to the "ear" on the new alt. being in a different location and had to re-wire the maxima alt's plug to the sentra's harness as they are different but it was easy to do. Plus junkyard was having a sale so I got it for $10, I did take it to an electrical shop to have it tested and to get a better pulley but it works great and is a big difference from 60 to 110 amps. Also the stock sentra alternator looks identical to the pathfinder alt. Edited March 25, 2012 by ahardb0dy Link to comment Share on other sites More sharing options...
JamesRich Posted October 1, 2010 Share Posted October 1, 2010 Anyone find a V pulley that fits the maxima alternator? I don't feel like making a spacer for a two piece pulley. I'm sure there is a car out there that has the pulley we need to just swap it out. James Link to comment Share on other sites More sharing options...
Kingman Posted October 2, 2010 Share Posted October 2, 2010 I used the stock pulley, and made a spacer from some steel tubing. Never had a problem with it,. Link to comment Share on other sites More sharing options...
schickdog Posted December 15, 2010 Share Posted December 15, 2010 Um, question... Don't you need to install the fan from the v belt alt as well onto the maxi alt? won't the maxi alt burn up without the v belt fan? I'm trying the same swap.

nunya Posted December 15, 2010 Share Posted December 15, 2010 I been running since aug 2009 (the day I posted here) with no v-belt fan, no issues. The Maxi alty has an internal one IIRC Link to comment Share on other sites More sharing options...
OfftourRoadie96 Posted December 15, 2010 Share Posted December 15, 2010 Is there an exact write up for the 1996-1999.5 R50's.....I'm planning on putting off road lights as well as a winch. Is the a direct bolt on Alt. ???? in 90 or 120? Link to comment Share on other sites More sharing options...
skulptr Posted December 16, 2010 Share Posted December 16, 2010 i hope so, my alternator isnt even keeping up with my heater and headlights anymore. when i come to a stop, in gear, everything comes down at least half power. Link to comment Share on other sites More sharing options...
schickdog Posted December 17, 2010 Share Posted December 17, 2010 My 88 is going to require taking the spacer off the pathy alt shaft and cutting it from 1/2" to 1/4" and putting it on the maxi alt. Not exactly a "true bolt on" for me, but nothing is ever easy. However, one week until Big Bend and some serious wheeling. Link to comment Share on other sites More sharing options...
Tungsten Posted November 22, 2011 Share Posted November 22, 2011 I just have one stupid question... So I found an alternator on a Maxima that looks pretty much the same front and back as a Pathfinder one does except with slightly more beef. Front Top Back Now when the pulley comes off it looks like... Is that how the V-belt pulley is? Would a V-belt pulley swap directly or do I need to make an adapter?

nunya Posted November 22, 2011 Share Posted November 22, 2011 That would be why a spacer is needed by some people (myself included) as I stated when I did mine, I just cut an old socket down to the needed depth. Still 0 issues since then with it as well Link to comment Share on other sites More sharing options...
Trogdor636 Posted November 27, 2011 Share Posted November 27, 2011 Although my free Maxima alternator didnt last long, here is a pic of what it looked like when I took the pulley off. I'm guessing yours was from a DOHC or newer Maxima? Link to comment Share on other sites More sharing options...
Tungsten Posted November 27, 2011 Share Posted November 27, 2011 No, it was from a SOHC VG Maxima. Upon further research it looks like if you own a 70amp alternator then the pulley will swap directly into the 90amp unit. The people that have to make adapters are the ones swapping the pulley from a 60amp unit because of the external cooling fins. Link to comment Share on other sites More sharing options...
Tungsten Posted December 1, 2011 Share Posted December 1, 2011 Pulley swapped directly and all the wiring connectors were plug and play. This is going from a 70 to a 90. More pics coming soon! Link to comment Share on other sites More sharing options...
Tungsten Posted December 2, 2011 Share Posted December 2, 2011 All done! Pictures or it didn't happen right? BEFORE AFTER Here is the old thing with the new pulley on it, just for fun! How it looks from the back end: There you have it folks. The easiest upgrade ever. Link to comment Share on other sites More sharing options...
DarkDragon Posted December 11, 2011 Share Posted December 11, 2011 Hey guys, I just did this swap yesterday. In the morning, my old alternator was running 14.3v and when I gave it load by turning on the head lights on high and the ac on full blast the voltage to drop to 13.3 and the car would stall out. In the afternoon I did the swap with a 94 Max alt. It worked great for about 5 minutes. I started the car and my multi-meter read 19v.wow what a jump. I gave it the load test again, dropped to 18v. Got below and tighten up a few thing, when I look back at my meter is reading 12.3v and dropping. Did I just blow my new alternator, fuse, or the flux capacitor? I can’t figure out what went wrong. Please help; I need this vehicle for tomorrow work. Thanks Link to comment Share on other sites More sharing options...
