Well I have gave up on finding a used alt for my truck so I have decided to go the new route. My question is which one should I go with? My budget is only $300ish, so Tenney and a local company both were in question. Tenney has a 270amp shipped for $275, and the local company has a 240amp for $250ish. I will be running an AQ3500.1 with two DC lvl 4's @ .5 already did the big 3 and have a BT60 up front, and a BT100 in the back. Would the 240 be enough? And is there any other brands that have quality parts for around that price? Thanks.
