IGN2- not sure what this is, is it the same as IGN1?


no, it sends fire directly to the coil positive primary terminal when starting, bypassing the ballast that the current has to go thru in ign1 (run). This terminal is energized at the same time as the "ST" start ign switch terminal which feeds the yellow wire to the "ign" terminal on the starter relay. These have to be seperate (not connected to each other) terminals on the ign switch otherwise current would feedback from the coil to the ign switch to the starter relay yellow wire "ign" terminal which might keep the starter solenoid partly or wholly engaged at all times as opposed to just when starting & one of our left coast members just had a problem with that cuz the "awesome wiring diagram" in the archives improperly shows the yellow starter relay wire being connected to the ballast/coil. The seperate ign2 "full voltage" and ST "start" terminals on the ign sw are either both hot (when cranking) or both dead (in ign1 run)





That is right. Ign-1 is key on power like to the ballast and alt field. Ign-2 and ST both get the power in the start position as was said and as was also said they cannot be hooked together as when the key would be turned to the on (ign-1) the ign-1 power would go through the ballast and then backfeed to the starter relay and if enough volts get through the ballast to work the starter relay it would crank in the run posistion. I know as years ago I had an old ign switch and tried it as it was a Ford switch and had no ign-2 on it since Ford bypasses its primary resistor wire with the starter solenoid. Ron




I'm rewiring the Ford 302 in my 37 pickup, are you saying that Fords don't need Ign-2, only Ign-1? Do Fords even need a ballast resistor with a points distributor ?
