I guess you know but.... if you got dwell, you then had to switch to timing, using a mode switch on the unit. You also needed to be in 4 cycle mode. You also can't have solid copper plug wire on no. 1. Don't look too long, most people just hook a 12V car, truck, lawn mower, battery charger..... to the light for the few times they check timing. Not a big deal and if a 6V light can't be used on 12V, that's no good.
