So I've done a bit of reading and here is what I have. Red light comes on for a few seconds with key on then goes off. If I ground the sensor wire, the red light comes on but no fan. I've tested the fan independently and it works. I have 12V pos at the fan plug but no ground. I have continuity from the fan plug back to the plug at the ICM (CDI). So... it appears to me I have an issue in the ICM. I currently have a toggle switch providing ground when I want to kick it on but I'd prefer to put it back original (bike is new to me). Is there anything else I need to check for before I decide "IF" i want to replace the ICM?
