Ok I can't decide wether to do a Powemaster 140 amp One Wire alernator or a 3G Conversion with a 140 amp alternator. I need everyones opinions!
One wire alts= self-exciting. They are turned on when they reach a certain RPM threshold.Euphoric306 said:what's the name of that setup refer to (one wire) because it makes sense to me you need at least two wires (one for stator and the 4 gauge positive feed)
Hissin50's point is important to take notice of if you have underdrive pulleys.HISSIN50 said:One wire alts= self-exciting. They are turned on when they reach a certain RPM threshold.
Depending upon how the cold idle is set, the alt may or may not turn on with the cold-idle RPM threshold.
See http://www.geocities.com/smithmonte/Auto/3G_130A_Alternator_Upgrade.htm - all the tech data you could ever want to know and the differences between the 3G upgrade and stock 2G alternators.cradicg said:Is there anything special about the 3g that would outweigh rebuilding the stock alt? I have a great shop here in VA Beach that can rebuild alt's and starters, and even rewind them for whatever you need (my audio buddies use them for insane sound system power). Just curious cause this is on my list of upgrades for my 88 LX.
Sicarius428 said:I had a Powermaster unit and I switched to the 3G from paperformance and havn't looked back. The 3G puts out more volts at idle than the powermaster which is the most important thing for me sitting at a stop light with an electric fan. The 8gauge wire that the powermaster comes with is a joke... so you probably should get a better one anyways(fused 4ga.). Stick with the 3G.

The stock alternator does not have a large stud to put the power cable on. I am not sure how an alt shop would work around the 2G connection issue (so the two stock charge connectors dont get overloaded).cradicg said:While I have a fairly frim grasp on 12VDC basics, that article was a bit too geared toward engineers IMO. The jist of the article seems to be that a 2G alt only handles 60-75 amps, and that a 3G will handle 110-130. I also saw where some of the stock wires must be addressed sincle thier small guage can present fire hazards under new loads. Can you (or anybody) tell me in layman terms, why I could not just have my stock 2G rewound and rebuilt for 130amp capacity from a generator shop? I would of course have to address the upgrade of the old wires to handle the new loads, but that is easy. Thanks in advance.

Also I hooked my Powermaster up to 3 wire and it works perfectly and never had a problem with it. I'll go ahead and vote Powermaster!
