Ignition Issues - ‘74 Dart Sport
Check power in the "run" position at the key switch, and follow that out through the bulkhead.....standby............
Also check "the stupid" connector. This is a white rectangular connector which separates the wiring right at the engine from the firewall harness. These are prone to failure. Bypass it if it is at all damaged
Also look on the driver side fender apron for a small box with a (used to be red) reset button. This is the seat belt interlock. Permanently splice the two yellowish wires together, which break the starter relay connection when it trips
Below the ignition switch is not quite drawn correct. The starter circuit is isolated, all by itself.
S2-12Y activates the start relay through the forementioned seat belt reset/ interlock
J3 -12BR is the ballast resistor bypass circuit and is also hot in start, feeds full power to the coil+ for a hot starting spark
J10-12R is battery power feeding switch, hot at all times
J2A 12DBL (Dark BLue is the IGN1 "run" wire
Q2- 12BK (BlacK) is accessory
