When I turn on the head lights on my '78 US the high beam dash light comes on and does not go out when I pull the dimmer switch to low beam position. Also there is no power to the low beam fuses. Also no power to 87 socket for dimmer relay with dimmer switch in low beam position. Does this sound like a faulty dimmer headlight switch?

Thanks, which pin outs should I jump?

Greg,
This sounds more like a bad high/low beam relay XIV. It's normal closed for high beam then switches for low beam.

Disconnect gnd, pull the relay, and jump pins 30 & 87. Then reconnect gnd, and turn ign to acc. and headlamp switch on.

Ok so jump 30 & 87 then jump relay ground pin to ground?

Per your suggestion 30-87 jump confirmed relay is the culprit. Thanks.
