I run an elec fan on my radiator. What's the best method to keep it separated from my batts? I've read on here about a breaker? Can't seem to find the thread now.. Any ideas are appreciated.

You want to run a in line fuse so if when you get your fan it will blow the fuse and quit drawing juice Hope this helps you

I prefer circuit breakers.

I have allways ran inline fuses. But on my last build, I ran two circuit breakers from Advanced Auto wired parallel. I don't trust them because they are made in China. If I could find a quality high amperage one then I would run just one. The only advantage of a circut breaker is that it will reset itself after it cools down if somthing has a temporary short or gets accidentally grounded out. I would love to find a high amperage one for my alternator as well.

I would love to find a high amperage one for my alternator as well. Everything's on google. Just have to figure out how to get that info. Stromi your the man. You led me in the right direction...thank you Ok I found some 12v Manuel breaker. What amp for the fan? What amp for the alt My alt is a 16v 100amp Fan draws 40amps at start up maybe ? I'm thinking when the fan gets smashed the the amp draw will heat up And kick in. Even if its 100amp breaker. I just want to stop the short So it don't kick over to my coil and mess that up. The derby I'm going to only allows 1 battery.. Stupid rule IMO

do be careful with high amp breakers, you must find out whta the wire is worth. 100 amp breaker will hold long past the wire burning through. everyone has a fusable link in their system, the wire you use. Self resetting, high amp circuit breaker is the ideal piece. most of the stuff you find will be low amp self resetting or high amp but manual resetting. Bass pro shops or gander mt have 50 amp circuit breakers for trolling motors but they are manual reset. There are many self resetting breakers but they are 20-30 amp. Most of my fans start at 70 amp and run at 44 amp. Most auto fans are under half that.

amps has very much to do with wire gauge... so if you have a wire burning with a 100amp breaker....your wire is way too small.

So your saying you need to run battery cable to your fan? A fan that has a running amp of aprox 18_20? You need proper wire to go with the amp draw of the fan and the proper breaker to go with that. Tarus fan, oem wiring and 30 amp self resetting circuit breaker is a good package.

What's made my life easier with fans is building a nice study framework around my fan, rigid and braced. What trips breakers, burns fuses, burns wires and melts wires internally in fans is binding the blade against the shroud. Trim blades and shrouds to avoid this and beef up the structure its mounted to. Not just two ratchet straps.....

That effort makes dealing with melted wires almost go away.

I didn't say it was for a fan or otherwise just saying use appropriate wire for appropriate breaker or fuse.
