Where does the battery connect to a cooling fan?
For a remote battery, it can be connected to a power port in the engine compartment, but it should be fused. The red wire from our relay connects directly to the cooling fan, and the black wire from the cooling fan connects to ground, both wires will utilize our supplied fan harness.
Why do I have a GM 3 relay fan?
I try to show people how they can diagnose, fix and repair things themselves, grow their own food and preserve and store it. I strive to do something everyday to become more self sufficient; to be closer to my food, spend more time with my family.
How to straight wire a cooling fan to an engine?
The best way to test it is to bypass the fan’s normal circuit and straight wire the fan to the engine. Locate the positive and negative wires on the cooling fan. Cut both wires and strip 1/2 an inch of insulation off of the ends of the two fan wires. Connect one end of the 12-gauge jumper wire to the black ground wire of the fan.
What are the symptoms of a bad cooling fan relay?
1. Engine running hot One of the first symptoms commonly associated with a bad or failing cooling fan relay is an engine that runs hot or overheats. If you notice that your engine is running at higher temperatures than normal, that may be a sign that the relay is not functioning properly.

Can a single cooling fan be connected to a single fan?
Connecting a single cooling fan is a rather straightforward system, it relies on a separate temperature sender to switch the fan on, or you can utilize the cooling fan output if you’ve installed an aftermarket EFI conversion.
What should the temperature be for a fan to shut off?
The temperature sender, if used, is designed to provide a ground signal at about 185 degrees, and will shut back off when the temperature drops below 165 degrees. This wire (gray in our kit) supplies the ground signal to trigger the relay.
What do you call an auxiliary cooling fan?
