I’m hoping to get some help from those with some experience with the 1968 400’s electrical. My 1968 has been running great all summer after a few gremlins were taken care of. The latest one is a bit perplexing. When I put the driving lights or head lights on, the gas gauge goes to empty and the red indicator light in the center of the dash comes on which is the high/ low beam I presume. When I work the switch it doesn’t go out nor does the gas gauge come back. I’m assuming it might be the switch but thought I’d do a shout out here as well before tearing into things.

Thanks in advance,
