Re: Electric fan how big fuse and switch?
Absolutely run your manual fan switch through a relay. You do not want 20 amps going through a switch. You want to control the 12v signal to the relay. Go to BeCool site and download there installation directions. They show you how to do it. If you can't find it, email me and I can send it to you. I have it installed in my car and it works great. My fans pull 20 amps each and are fused seperately to the battery junction block. I believe they have a 25 or 30 amp fuse. I can check if you need the info.
