After I origionaly purchased I discoered blown fuse under seat;
. Replaced and all was well except as the engine warmed up the fan would come on for only 10 seconds or so and cycle back on in about 10 more seconds. My brogher has a 2004 eiger and the fan does not cycle like that.

Now fan is dead. fuse is good. if I apply 12v to fan it works well. When I jump out the thermal switch at bottom of cylender. Nothing.

There must be some othe gizmo in that system like a relay that I am missing, any help would be just great. thatnks.
