Gene - What relay system did you use?
I am working on two trucks (55 and 58) that have blinking/flashing high beams. Have already went down the path of re-grounding the head light buckets, both trucks have new wiring harness (M&H) and relatively new switches and floor switches.
Both have halogen head lamps.
Had to get the alternator - charging systems setup for 3 wire and have good voltage going to the battery, amp meter in dash shows charging now. Both had one wire systems that did not charge; installed new alternators on each one.
Amps out the back of the alternator 17.5 on low beam, 26.4 on high beam. (relative measurements on both trucks)
Plan on checking the current draw on the lamps and checking out the headlamp switches today.
Thinking that I need relay systems and/or new switches since I am unsure where at least one the truck's headlight switches came from....
