Installed Dual Fans and Relays in My RV
Hayden® - Temperature Switch
I installed 2 of these units in my RV last year for a dual fan setup. I used wire larger than on unit and soldered all connections. Units worked fine for many cycles one afternoon was driving home from vacation and stopped for fuel. When started vehicle i notice engine temp climbing rapidly. Turned off engine and had one fried fuse totally melted? Fortunately I had a spare relay and fuse onboard I changed out and Walla it work perfectly and have not had any more issues? If anybody has an answer it would be much appreciated.

Temp Switch
Hayden® 3647 - Adjustable Cycling Cooling Fan Temperature Switch
I will say that it looks good , installation might be a little tricky when it comes to the ignition wire hook-up, but the main thing is the wires were not as heavy
as the ones on my car. And I had some question about the fuse rating of 25 amps, vs the 20 amp low speed setting for my fan motor, and the additional 40 amps for the high speed setting.
