Curt came down to Fresno yesterday and we spent the day installing his Vader headlight kit. Before buttoning up everything, we tested the new Hella H4 units and I saw two low and two high beams.
Once we had everything locked down and had relocated the headlight motor relay - NOTE: 35 year old micro nuts and bolts rust together just like large nuts and bolts - the headlights came up and the passenger low beam is just ever so dimly glowing. That is about when we found the cracked switch, pulled it out and did a Rube Goldberg tie wrap, fiberglass packing tape rebuild and he made a dash for home before it got totally dark on 99.
So everything worked fine - then it didn't. I suspect ground or wiring, but had no time to troubleshoot.
