wanting to install some electric fan in my 85 f150,

question is, how do i get the highspeed to kick on? i tested to see if the fan works and it works but its not like highspeed.

do i need to get some converter

 

What alternator do you have? Electric fans pull quite a bit of amperage.

 

We will need more details to be able to help. Do you have a specific model fan you are planning to install? Or are you still shopping?

From the "Questions You Didn't Ask" department, what's going on with your stock cooling fan? If your truck originally had a thermal belt-driven fan, those things are amazing when in good working condition. Given the chance to spend your time and money, I'd much rather run a stock belt-driven fan than convert to electric.

 

i got it, thx for the help.
