Re: Alternator + Electric Radiator Fans = Need Recommendations
Others will chime in, however, I run dual Flexalite fans. I have a 94 internal reg. Alt. But the alternator does not power the fans. They get the power from your battery. The alt. just replaces the charge. I run a dual Batt. Setup and my fans draw from the second battery. Many run a single. When I did I had a Optima Yellow top Battery. Was fine for years. I hear they can run your battery down in really hot weather but I have never experienced this. Since 2013 I have been running dual Walmart $60 deep cycle batts that have a one year warranty. So far so good. I dont drive the truck much but it starts every time and I have no worries.
Oh and I second the 3 or 4 wire.
I have had a one wire and it was fine.
But if you read up the multi wire units boost output when needed. (elec fan setup maybe)
