i have another problem that has surfaced since i have put on the UD pullies. this is a problem however that i did notive before the pullies were on but they just got a bit worse. basically, is the day light with no lights on or any electronics everything runs fine, engine temp is normal now. but at night when i put on my head lights lets say and the occasional blinker i get my headlights dimming out, my dashboard and other in cab lights dimming out. also i noticed that once i use things like headlights or radio or whatever, my engine temp. will actaully rise. i also have had times at night where ill drive and have the lights on radio on ect. and ill feel the night to floor it, ill actaully have the dashboard just black out, guages will go down and everthing. if i get a new alternator, maybe a stronger one, will that help with this problem. i beleive its the original one.

It's time to upgrade to the 3G alt and not put the underdrive pulley on the alt.

If he isnt racing it every weekend he should put the stock pullies back on.
