Hey guys. I just got (another) LN-7 wire feeder but it seems there is something amiss with the control board. When pulling the trigger on the gun, you can hear the relay and the solenoid open, but there is no power going to the motor. I verified this with a multi-meter, and checked ohms with a multi-meter on the motor. The motor is good. Verified it with a 9v battery. I'm thinking since this is a 1980's wire feeder that lincoln doesn't support it anymore, so I'm trying to troubleshoot and hopefully find the faulty component/components on the board that are causing this. Does anyone on the forum do repairs to these?The board number is G1706-1Thanks!AndyESAB 350 MPI ESAB 330I CVCCLincoln Idealarc 250Eastwood TIG 200Hobart Ironman 240Hobart Plasma CutterLincoln 110v MIGCH 110v MIGMK Industries Cobramatic with Prince XLMiller XR Wire Feeder
