So I seem to be having some chronic issues with the last two aftermarket headlight switches I have bought. The first one smoked it's dimmer reotstat. The second one worked for a while and now the instruments don't light up. I checked to see if there is voltage at the switch where the grey instrument light wire hooks up to and there is none. It's a brand new wiring harness. Bad run of aftermarket switches??
