rocking.that.eclipse Posted April 10, 2012 Report Share Posted April 10, 2012 Ok so i have installed my new 220 amp mechman alt on my 01 eclipse. I had a few problems. The belt squeels on start and when the alt is under a big load. I think this is just from by belt being too tight but I am open to hear other suggestions. Now the bigger problem for me is that when i hammer down on the gas and the rpms are around 4500 or 5000 the lights dim in the interior and the battery and e brake light comes on... any ideas on that?

Kranny Posted April 10, 2012 Report Share Posted April 10, 2012 a tight belt wouldn't cause squealing. that doesnt even make sense. a loose belt/not enough belt wrap on pulley will cause squealing. as for the bigger problem, i cant really help you there Quote Link to comment Share on other sites More sharing options...
Rebel4055 Posted April 10, 2012 Report Share Posted April 10, 2012 (edited) Not enough belt wrap? The other issue seems like the alternator is not able to produce anything and it messes with the computer. When my battery went bad my A/C light was coming on and flashing.

rocking.that.eclipse Posted April 10, 2012 Author Report Share Posted April 10, 2012 The belt has a full 180 wrap on the alternator. it isn't slipping at all. I had my friend stand and watch the belt while i revved the engine and it didn't slip even at redline and i read somewhere that if the belt is too tight that it will cause the idle pulley to squeel Quote Link to comment Share on other sites More sharing options...
kickass audio Posted April 10, 2012 Report Share Posted April 10, 2012 Try the water trick to see what is causing it to squeal. Spray just water on the flat side of your belt, if the squealing goes away then you have a tension problem and i suggest replacing the tensioner and belt and cleaning up all the pulleys with brake parts cleaner to make them oil free. Now if you spray the water on the ribbed side of the belt and the squealing goes away then you have a problem with the alignment of your pulleys and need to find which one is off center and correct it. The ribbed pulleys should all line up perfectly with the crankshaft pulley at the bottom of your engine. Belt wrap is an issue where you dont have enough surface area of the belt coming into contact with the pulley that has a strong demand (alternator, power steering pump, etc). Normally most pulleys have at least 1/2 of the pulley covered by the belt, if you dont have this then you should look into getting a pulley to put next to the alt to get the extra grip on the alt. Also belt slip on an alt heats up the pulley which in turn heats up your alt really fast and can burn it out so get it corrected as soon as you can.

So possibly not all the pulleys being lined up will make a squeeling too? Quote Link to comment Share on other sites More sharing options...
Rebel4055 Posted April 10, 2012 Report Share Posted April 10, 2012 (edited) Yes. Can also shred the belt if it's bad. Edited April 10, 2012 by Rebel4055 Quote Rest In Peace mother.
