Elec woes, crank, no start after running then parked.

Thanks J, yep, I foolishly didn't bring "supplies" this time as I was staying in town.
For a quick spark check(on any wires) I usually use a timing light. I position it so I can see the flash(or no flash lol) from inside car. Frustrating/embarrassing as f**k. Lots of compliments while I have hood up looking like a fool.
Just stopped at parts store and bought a SMP/Blue Streak coil UC12(no specs of course), SMP Ballast resistor RU4 ordered, no specs lol. I'll chk SMP site for specs(not holding breath)
Travel kit includes
Spare br
Spare coil
Timing light
Spare ECU(coin flip?)
Voltage reg
Voltmeter
CAA lol
Bring a alligator clip jumper wire with you to jump the terminals on the ballast.
I believe you have an intermittent short or break in voltage to those wires or via the ballast itself.
A spark checker you use between the cap and one of the plug wires is a good one too.. or just pull a wire and, slide the boot back some and look for spark during crank while holding it an 1/4 from the plug.
