30amp for each fan right? Those fans combined draw more than 30amps IIRC.
I had to use a 40amp for the bigger fan. Couldn't figure it out until I realized it was tripping my 30A breaker.
Maybe it was a bad breaker. It took me a while to diagnose because the breaker would reset. I figured the 30A was borderline. Or maybe the 30A breaker was just faulty but I never had a problem with it once I did 40A.Interesting, I was able to use a 30amp on each circuit.

I only hooked up one of red hot wires and it turns on both fans...30amp for each fan right? Those fans combined draw more than 30amps IIRC.
I can't find a 40A fuse to plug into that in line fuse holder. The largest one is 30A. Do I need use a breaker? Or a different kind of fuse?I had to use a 40amp for the bigger fan. Couldn't figure it out until I realized it was tripping my 30A breaker.
I think so! If you could that would be awesome!!I have a set of windstar fans in the shed I can hook up to get exact amp draw readings from tomorrow if you need to. The thunderbird fan on my F150 spikes up to 56 amps on startup from a dead stop. The startup spike may be what's killing that fuse.
Yeah I used a 20A for that. Did you not use a fuse between the relay and battery hot wire? I tried that as well and the relay got destroyed.I ran mine with a 15 amp fuse. But then I was just sending power to the relay that was controlling the fan.
I don't get how because there is 2 red wires and a black wire coming out and I only hooked one of the red wires up. I was told that each of the red wires send power to each of the fans...not.both. Unless one wire is high speed and the other is low speed?Then you have both fans tied through a single 30 amp circuit, that's not correct.
Installed and wired up the windstar fans, they work great! View attachment 218780
However, I could not get them to run through a fused relay and fused switch. I was using a 30A fuse and wired everything exactly like this says too and after the first time running them, I have blown the in line 30A fuse everytime right when I turn the switch on.View attachment 218781 View attachment 218782 I have checked all my grounds and checked and fixed all my connections and still cannot figure it out. Anybody have any tips or do I need to run a larger fuse for these?
Awesome info! I'll look into wiring 30 amp breakers and see how it works out! Thanks Chad! You're the man!Each of those fans draws around 35 amps when they start and will settle in around 20-25 amps when running. You could go with a 40 amp fuse in a bigger fuse holder or install a 30 amp circuit breaker for each fan. Circuit breakers are slower to trip than a fuse.

I think I found what's going on because I just jumped the other red wire and both fans came on again...So somewhere in this loom, I think both fans tie into each other..if that's the case, then do I need to use like a 50A breaker??View attachment 218911
Cool update tho, got some extended stainless steel braided brake lines made to accommodate the droop when I decide to fully flex.View attachment 218913
