Frogger2662 Posted July 27 Share Posted July 27 Upgrading my charging system to 3g. Right now it is a 100 amp one wire gm. My bracket system is a 1984 5.0 v belt set up. Looking at either a 130 or 150 amp. I will be running dual belts. What year model altenator will bolt up? Link to comment Share on other sites More sharing options...
BigBrother-84 Posted July 27 Share Posted July 27 Check my thread "Big Brother is going 3G". I am proceeding in couple of days, finally grabbed all required parts. I asked a lot of questions, and guess what, sure it is that I'll have some more while swapping the alternators. I'll post a lot of pictures while working on it. Hoping this will help! EDIT: For the model, I followed Bill's advice. Link to comment Share on other sites More sharing options...
ArdWrknTrk Posted July 27 Share Posted July 27 With low mount & V-belts you're going to want a 8.25" C-C alternator, so it can swing for adjustment. This comes from the 3.8 V-6 found in 91-95 Taurus/Sable If you have a later 5.0 EFI with the top mount alternator you need the 7" mount from a 3.0 V-6 (same cars and years) Link to comment Share on other sites More sharing options...

I have the double pully allready. Will I need the shim to go behind it to keep it from rubbing. Readong the document section it sounds like I will.

Gary Lewis Posted July 27 Share Posted July 27 That what I was wanting to know. I have the double pully allready. Will I need the shim to go behind it to keep it from rubbing. Readong the document section it sounds like I will. You might consider installing a load reduction control (LRC) voltage regulator before installing the alternator - assuming it doesn't have one. Most of the LRC regulators are white. You can see how they work in this thread. Link to comment Share on other sites More sharing options...
Frogger2662 Posted July 27 Author Share Posted July 27 I was reading about the lrc regulator. The link in the document section no longer works. At least not for me. Anybody have a current link to the regulator and shim? Link to comment Share on other sites More sharing options...

ArdWrknTrk Posted July 27 Share Posted July 27 I think I just found the info on the lrc regulator. Thanks Just need to find the shim. The shim can be any thin 17mm spacer (depends on how far off your pulley is) A 5/8 washer is usually sloppy enough to fit nicely. Gary got the L&L double sheave pulley that came from my kit. I think he turned the boss back to get more thread engagement, but mine has been fine for over a decade with a spot of loctite. Link to comment Share on other sites More sharing options...
