Re: Alternator Squeal under load?
[img]images/icons/tongue.gif[/img] Don't forget here, Piggy, that when you increase RPM, the alternator can then do more work.....that is it can AT LONG LAST get the battery(s) charged up and replace the stored current that you stole by running the lights, fans, stereo, 12V juice blender, and your Jeepchick's 12V hair dryer all while the Jeep was at VERY LOW RPM [img]images/icons/frown.gif[/img]. What is happening is that the alternator is doing what it is supposed to, and that is crank out gobs of electrical current. It just so happens that when you have batteries which are calling for replacement current to rebuild the storage that you so recklessly pilfered, and the accessory loads are also sucking current like crazy, something has to give and it is the belt. There is simply not enough pulley area in contact to do the job AT THAT POINT. How about a nice dual belt setup?[img]images/icons/crazy.gif[/img] My crack moonguy alternator team is ready to parachute in and start stripping your Jeep in preparation for the big changeover to dual belt alternator drive.[img]images/icons/smile.gif[/img] You can also opt for a larger diameter pulley from Summit.[img]images/icons/tongue.gif[/img]
