Yes, I plugged the two wires by the gas tank back in before testing the single blue wire by the pull start. I don't have a battery in the ATV but have been using a jump box to power it. When I turn the key on the red light comes on for a couple seconds and then turns off. When I first started to ground the back wire, the red light would come on and I could hear static like noise coming from the area where the two plugs are by the gas tank. Now i cannot get it to make that sound again? Could that have been the fan control unit? Let me know what I need to try now. P.S. - the single bullet connector behind by the pull start is a pain in the a$$ to get to and put back together.
