I traced the wiring from the small relays to a larger relay. The larger clicks and has voltage coming out so I'm calling it good.
I hit all 17 of the smaller relays with, my special electrical, hammer and knocked the cap off of one. Watching the operation of the now bald relay, it seems that a warm relay is a good relay.
I've two sizes of relays with the larger being 2"X2" all with the same part number and the smaller relays are smaller than an inch square and again they all have the same part number. _
The smaller ones have 5 pins roughly in this pattern
The || pins are dark and the others are lighter in color.
BK, I managed not to hurt myself while jumping on the dimmer switch which is activated by the blinker stalk. The bright light signal illuminates on the dash properly. If I activate the switch fully the dash high beam indicator stays lit and if I move it marginally the indicator light flashes as expected. The actual head lights don't light.
I did this in the dark to give me better conditions to see if there was a quick flicker or a dim glow but there was nothing.
I'm going to the auto parts store to buy relays. I'll let you know if that helps.
You do understand that you need to use a special electrical hammer on those things, right? Regular hammers just won't work.
Oh and Len, my truck driver cousin gave me not only a special electrical hammer but also an official Detroit spark plug tool and told me to keep my eye out for a left handed monkey wrench when I bought the bus.
I thought he was pulling my leg particularly when he mentioned the monkey wrench. My grandfather used to send me to find his all the time. However Steve, the cousin, took the time to explain that I would need it on a Detroit and it is indeed a joke when mentioned in conjunction with a gas motor. I was glad he cleared that up. He also warned me to be careful as each tool is very powerful.
