Ok i know i know i have heard everyone say that the 145 amp will not help with the amp drainage when the fans turn on. Now i just wanted to put one on to help out anyway and i got a good deal. The real question is will this 145 amp fit on my 02 avalanche with a 4 pin connector with no other new parts (ie longer belt or new pullies or other stuff)? Also people with the 145 amp alt. does ur voltage meter on ur cluster stay at like 12 volts when ur sitting in traffic and both fans are on high and stay constant at 12v. Mine does with the 105 amp. Now i understand the quick amp draw happens with the 145 too and im ok with it. I just want to know if like i said above stays low with the 145 at idle or goes right back up to 14 v. thanks.

BTW I have the 05 fans
PS i know the cluster is not accurate but its just to gauge things.
