Guest Just_Rob Posted January 20, 2009 Report Share Posted January 20, 2009 i think is dc, do i need mla module even if its a 1 wire alternator? If it's one of our Dual Alternator Brackets I will be more than happy to help with the belt situation, but I will need some info and I'll get you the correct belt number.. It didnt come directly from us though.. I wont say anything about the alternators that your running other than if your voltage is going down to 11v at an idle and comes up with throttle, the alternators are NOT charging squat at idle (typical) and an MLA module wont fix that, it wont make a BAD alternator GOOD.. It WILL however definitely make a good alternator better, an make a great alternator AWESOME.. And lastly, if you have a typical "One Wire" alternator, your S.O.L for running a module.. One wire alternators = GARBAGE!!! Only place they have is as a last resort... If you need any other info, drop me a PM or call me and I'll be more than happy to help... 888-441-0144 Quote Link to comment Share on other sites More sharing options...

Guest Just_Rob Posted January 20, 2009 Report Share Posted January 20, 2009 Just as a side note for you guys with late model GM trucks and SUV's with GenIII and GenIV Vortec V8's, they idle at 550 rpm almost without exception, most definitely NOT 800 RPM... At 550 RPM engine RPM depending on pulley ratio alternator RPMs vary between 1950 and 2200... From what I have actually TESTED, both on vehicles and on our test bench I have never seen a 300 amp alternator other than ours that will charge more than 30-40, maybe 50-60 amps at best at idle.. 60 amps isnt enough to even run a vehicle, let alone powering accessories...
