Re: Main Gauge Lighting - 67
Even though it is on the same circuit board, if the turn signals and gen light were on the same circuit, then they too would light when you pull the main light switch. At this point, all you can do is trace the circuits. A quick way is to pull the bulb and test one terminal for 12V and test the other terminal for continuity to ground. This will tell you if you are not getting voltage or if you have a ground issue.
