back to numbers.. if the original resistor is giving a 7.8 volt drop measured across it…. then the rest of the cct can’t be 0 ohms in the selenoid
if the selenoid was 0 ohms …… the ballast resistor (in series) then becomes THE major resistance point and would absorb the drop of a full 12 volts when measured across. (ohms law)
As FR pointed out “or just resistance in the rest of the wiring, or whatever.”
you need to find out where that resistance is hiding … (possibly poor -oxydized connections)
glad my suggestion worked just measure the resistance of both resistance in parallel and get one single resistor t. of the eqv. value .o save space …. 🙂
or find the problem …measure the solid 12v (to a solid ground) incoming to the choke button….. measure same voltage AFTER & holding the choke button (should be 12v also) measure pre-ballast should be 12v (if no resistance encountered yet)
if not 12v to ground….. entering the ballast resistance…. you have a resistive path back to the choke button
