Ok, I'm assuming this is a voltage regulator... However it is not regulating the voltage. When my electric fans are off, its over 16 volts to my gauge.

I would like to replace this instead of rewiring a new one (I tired that).

It has one wire in and one wire out.

 

It looks to be a voltage regulator but without knowing what it was originally in, nobody's gonna be able to help you by the pictures you posted. Your profile says that you have a 2005 F 150 and I know that it's not from that.

 

Thats the problem all the ones listed for it or the motor don't look like that.

truck is a 1953 F100
engine is 1968 429

 

So is your truck converted to 12 volts? If so, are you running a 12V generator or an alternator? Single wire GM type alternator or 68 Ford alternator?

one in one wire out? looks more like a cut out, or relay to me.

 

After hours searching the internet... It is a voltage regulator for a mid-60's Mopar
