I have a 93 isuzu pup, bagged and bodied. After the body drop I took the engine driven fan off an changed over to a electric fan. After the change my Alternator hasnt been able to keep up with my fan and air pumps. The battery keeps dying and wont push the pumps. Not sure what the fan is pulling in amps, but I know the pumps pull about 39 amps. I know the stock alt only puts out about 50 amps. SO what is a easy and good upgrade? would like at least 100 amps or better... thanks!
