Subject: Re: Odd Signal and Light Symptoms. by dstaley on 2009/7/30 20:20:57 Seems like a relatively straight forward thing to check. With the bulb/socket out of the lens, measure the voltage on the ground pin with respect to the engine block. If the voltage on the ground wire/pin varies by more than about 1/2 volt, you have a grounding problem. If possible, check the base of the bulb (the cylindrical part, I'm not referring to the contacts) for this measurement. If ground voltage is stable (less than a half volt of fluctuation) while in operation, check the voltage on each of the supply wires at the light socket. Note any anomalies... |
