I have decided to get me some electric fans for my truck.
I believe my alternator is the stock unit on my 86 c10.
Got some ls1 fans off ebay for about $70/shipped...and got a vsc to control them.
Do I need to upgrade my alternator? I have not got the fans yet, maybe this week, I hope, or next. Not in a big hurry to put them in.
Let me know, comments/advice/suggestions...
thx
John

i sure would a 86 camaro 96 amp alt would be a direct swap..
why they don't put higher output alt's on your trucks i have no clue.

sweet..thx :)

I haven't had any problems with mine, and as far as I know, it's a stock-output alternator.

I went the low buck, higher hassle route and just went to Advance and scored a kit from there. I bought two of the 14" fans and secured them to my radiator diagonally from each other.

It was my experience that they drew a lot of current, but at first I had them powered by a loooong wire that went from the battery into the cab, through a 30A inline fuse, through a 30A toggle switch, then back out to the fans. You could always tell when I switched my fans on, because my voltage gauge would always drop to around 10-11 volts at idle. Not to mention, I torched the inline fuse and/or the switch every 2 months or so.

I finally got wise and had a mechanic friend hook up one relay for each fan and a common thermostat switch. Since then, I haven't had a single problem at all.
