The Stovebolt Site Forums The Shop Area The Electrical Bay Electric fan and engine rpms

Don’t know what to think i have a 52 Chevy truck
With 235 engine i put in a electric fan with a switch so I can turn on and off anytime,
I shorted out the fan wire between the grill and fender one day and smoked the relay.
I replaced the relay and the toggle switch as well. so today I was running the truck and noticed with engine rpms up the fan speeds up at idle fan is off and that’s with the switch off flip the switch to off and on and fan works fine
Anyone have any thoughts on this and should I just leave it?
Thanks

Sounds like the fan switch was off and the fan was off. You turned switch on and the fan came on. Sounds good to me
Can you try that explanation again? Just for me.

This part:

Do you still have the belt driven fan on the motor?? If so when you rev the motor the electric fan is pin-wheeling due to the increased air flow. If this is the case I wouldn't worry about it, its not hurting anything.

Will do my best to re explain rev up the engine fan spins new relay and new toggle switch
Engine at idle fan is off if I flip the toggle on fan works as it should.
I didn’t hook it up with a temp sensor.
Just seemed hard for me to explain issues .always appreciate the feedback

Thanks Dave one less thing to worry about.
