I've been over the wiring. I'm fairly certain wiring is good. Bought all the wiring from Year One back in 06, and made a ground harness that runs back to the battery. Car spends most of it's time in a climate controlled garage.
I messed up my description a little there. Sorry. I've checked both ign1 (run) and ign2 (start) without cranking (starter relay trigger unplugged) and everything is normal. The last check I did, the 13v is run and the 9v is ign2/start while cranking. I also pulled the ignition switch and hooked it directly to the battery to check both circuits and no voltage drop.
Battery is almost new, spends most of it's time on a tender and had no trouble starting my 64 C10.
