Wiring question?
 

My car came with dual electric fans. Both of them come on at the same time. Shouldn't one run all the time and the other cycle on? Anybody know how these are wired? Of sure what brand it is. Don't have much to go on.

Never heard of it. Electric fans are turned on by sensors. Only should come on when a certain temperature is reached or u are running climate control. According to what u are saying they are running normal

The o ly pro lem with them both coming ob together is the amp draw is dimming my headlight. They alleged to be wired right. I have a high output alternator. Maybe I need a stronger battery.

Are you running any underdrive pullies? and what is your car idling at (rpm)?
