dual fans?
we put dual fans on my sons 63. the circuit breaker keeps kicking when it gets warmed up. can I put a bigger circuit breaker on or should I wire them separate with different relays and breakers?

Re: dual fans?
Why two fans? How big are the fans and which fans did you get?
Many electric fans pull huge amounts of amps when starting. I suggest using relays to draw your power from the battery directly as well.

Re: dual fans?
Got A/C?
Wire the one to come on when engine starts and then the other @160 if that’s what thermostat is. If you have AC, then use a tri-nary switch to kick the one on with AC and at temp.

Re: dual fans?
No need for dual fans, just use a 16” spal fan, puller that pulls at least 2200 cfm

Re: dual fans?
I would wire them with each having it's own breaker and relay but controlled with the same sensor
