Need some advice - here's the background. A friend bought an 08 D7 with about 3000 miles on it. Everything worked but the headlight. Rather than tracing down the problem he bought a used wiring harness and we replaced the harness on the sled. We fired it up and the headlight worked. He took it out last weekend and when you hit the high beam button, the grip warmers shut off. Also, if you wiggle the switchblock, the gauge readout flickered and the headlight went off. Would these problems be related to the wiring harness or the switchblock or both? Could it be a stator problem? He wants to sell the sled to my son at a heck of a deal but we need to get everything working for the rest of the season. Any help would be greatly appreciated!
