Cooling fan on constantly

[benehr8]

Woke up in the morning to my cooling fan running. The key was out of the ignition. The bike hadn't run for 14 hours. Started the bike to recharge the battery then disconnected the battery. Help please

Try a new relay, cheap easy test of the most likely culprit.

I'm surprised that the circuit can be hot with the ignition off. If my coolant fan is running when I shutdown the ignition the cooling fan stops

That's why I suggest check the relay, it's not a normal condition and the relay is one of the very point where this failure state is possible.

Just go pick one up at the local auto parts store. There pretty cheap.

Standard headlight or horn relay should do. Probably 4 wire.

Here is a section of the cooling fan circuit. It gets direct power from the battery through fuse #7 bypassing any switch. If the cooling fan relay contacts are fused, then the cooling fan gets constant current with no way to turn off other than removing the relay, fuse or battery.

Ghost Riders, turning things on and off. Occasionally take the bike out for a spin and bring it back hot. Gotta get a Ghost Ryder alarm system for protection.
