TC10284 109 #1 Posted April 7, 2019 Just got a 73501 520H running today. None of the gauges work on it. Fuses are new and are not burnt out. Have checked the main molex connector and fixed any pins that were messed up. The only gauge that works is the vacuum gauge since I don't think that relies on power?
