Re: Wiring Question

For some reason the even numbered pages of the 38-39 shop manual do not seem to be visible when viewing on my browser so maybe the copy on site is corrupted. If you have a printed copy, on page 22 there is an illustration showing the two switches and how the same wires connect to each version.
That wire from the starter switch looks to be a feed from the incoming power at the ign switch and via a tie point on the starter sw and then on to the light switch as a possible feed for the switch and aux fuses. I am wondering if the jumper is needed on the 39 switch. Looking at a 38 diagram it is clearly shown but on a 39 diagram it is not present.
Do you have both switches? If so, can you ohm out the switches to see if the wire to the terminal gets power independently on both and if not, can you verify on the switch you have if it needs the jumper.
Since I believe sealed beams were known to be coming along maybe there is a provision in the 39 switch to make an easy transition for operation with either style bulb.
