[quote=Teds58Panel]I will be adding a jumper wire (I just replaced my ballast however.) But I am sure that would be good for a number of test scenarios.

Rich, what is that stuff called? JB Weld?
Grigg, I will add some of that - especially the feeler gauges. [/quote]
The stuff I have now is called Everbuild stick 2 but I am in England, sure you have something similar in Home Depot.
Probably your most useful tool if you break down is a cellphone, it's the one thing I feel very exposed leaving home without, in an old vehicle.
