Miguels Posted August 5, 2013 Report Share Posted August 5, 2013 tacomaguy my mechman did that.. it would whine like crazy even with no load.. would spike to 15.9.. shorter belt helps with the smaller pulley it comes with my logshttp://www.stevemead...-my-new-set-up/my blow through loghttp://www.stevemead...future-updates/ 96 ss http://www.stevemeadedesigns.com/board/topic/164094-96-impala-ss-build/ Link to comment Share on other sites More sharing options...
MonkeyMan Posted August 5, 2013 Author Report Share Posted August 5, 2013 Its charging at idle no worries, will happily power all the stock electronics at idle (measured 45amps with all the lights on), without the voltage dropping below the unloaded voltage (15volts cold, 14.6+ hot) Its just when at idle (14.6volts) blip the throttle, and it spikes to over 16volts....

Kranny Posted August 5, 2013 Report Share Posted August 5, 2013 where did you get the alt from. Link to comment Share on other sites More sharing options...
tacomaguy1 Posted August 5, 2013 Report Share Posted August 5, 2013 An alt shouldn't charge that high if its not designed to?....no matter what, with belt slip or whatever Idk maybe I'm wrong...I thought they had regulators to not charge past a certain voltage Team Flex Issues Link to comment Share on other sites More sharing options...
MonkeyMan Posted August 5, 2013 Author Report Share Posted August 5, 2013 http://www.youtube.com/watch?v=Y6yRO9RoqUU excellent, that's exactly what mines doing I shall try to find a shorter belt, or add another idler pulley in (and a longer belt) With my spring loaded tensioner released, I had a 2220mm belt length with the stock alternator, With the aftermarket, I have 2215mm (edit, I typed it wrong), so 5mm shorter.... so, I might get a 10mm shorter belt as it should still fit, and put a bit more tension on it...

MonkeyMan Posted August 5, 2013 Author Report Share Posted August 5, 2013 went for a drive to try and find a shorter belt, came back, and the hot charge voltage was down to 14.4volts.... a bit more realistic... then I decided to clamp the idle output current.... only got about 85amps... I'd say the belt is slipping pretty badly... Link to comment Share on other sites More sharing options...
