thanks to some help I got from Pabear determined I have a bad ballast resistor on my 1970 mustang (would not start). Try tracing coil wire but not clear where ballast resistor is. In reading other posts sounds like it is a thick pink wire but don't see anything like that under the my dash. Also putting in flamethower and Pertronix igntion - read I should by pass resistor - thought if I can find it I can splice into wire before it. Appreciate any help. thanks
