Siete_Cinqo Posted October 23, 2009 Report Share Posted October 23, 2009 If it's whining, it's because the the belt is slipping. Quote Random vids of the Avalanche My link Team Bass-Hz Link to comment Share on other sites More sharing options...
skittlesRgood Posted October 23, 2009 Report Share Posted October 23, 2009 It may be getting hot if you are pulling a lot of current at idle. It has thermal protection that will back the voltage down when it gets hot. It does not cool as good when it is not spinning fast. . .You woudl hear the belt if it was slipping. . . BRian not always.

If I was an asshole, you asked a stupid question or you had a fucktard attitude... or I was in a bad mood.

Iraggi Alternator Posted October 23, 2009 Report Share Posted October 23, 2009 Im gonna say its a 99% chance your alt doesnt have enough idle current to roll up your windows and charge a battery. Dom hey hey come on now guys, trying to get some help. Quote Link to comment Share on other sites More sharing options...
Iraggi Alternator Posted October 23, 2009 Report Share Posted October 23, 2009 Whining is producing current. Screaching is belt slipping. Quote Link to comment Share on other sites More sharing options...
bkolfo4 Posted October 23, 2009 Report Share Posted October 23, 2009 Unless it has been sprayed down with something, I would bet while you may not hear it non-stop, you would get some type of squeek every now and then when bouncing the RPM's up and down.

clouduz Posted October 23, 2009 Author Report Share Posted October 23, 2009 well, the whining is brief about 30 secs to a min and only when i haven't started it in a while. As for pulling current at idle, shouldn't when i'm NOT running anything like I said in a previous post, stock gave better voltage at idle. that's with or without running anything. With my mechman voltage slowly drops and drops until i revv it some not fun when it's hot and I want to run the a/c I have to keep it revved to about 800 to keep it at 14.2 volts, stock stayed at 14.3 without revving. and i'm almost sure it's not slipping, i have no problem putting on a shorter belt if it'll defintely help i'm just worried if it will be too tight and eventually pop b/c the pulley on stock and mechman are same size. Stock pulley was small to begin with Quote Link to comment Share on other sites More sharing options...
clouduz Posted October 23, 2009 Author Report Share Posted October 23, 2009 well, rpm's don't jump at all if it's sitting at idle 600 engine rpm it doesn't move at all, just voltage starts to go down needle doesn't move. let me go back and look at the service manual to make sure i read the min alt current needed Quote Link to comment Share on other sites More sharing options...
clouduz Posted October 23, 2009 Author Report Share Posted October 23, 2009 okay yea it says 65a min mechman does produce that but i think irragi might be right about not enough idle current, b/c this is the list of the first few off the dyno sheet Stock Mechman 67 37 83 68 94 95 112 147 AFTER doing the conversion the output i get is Stock (83) Mechman (68) I think I need those 15 amps Quote Link to comment Share on other sites More sharing options...

basebalz13 Posted October 23, 2009 Report Share Posted October 23, 2009 when you look at your DYNO sheet it says- 1800 RPM's- 68? then 2400 RPM's- 150?
