Coil/ballast resistor draw drop a whole volt?

You will need to operate the electric choke via a relay triggered from ignition run circuit. I use the 12v side of ballast resistor for trigger #85-86 terminals, and fuse the power feed to choke with 10 amp fuse.

Also in addition to cleaning and correction of all connections and conductors if needed in ignition circuit outlined by 273, don’t forget to clean battery terminal connections, as well as engine block grounding conductor, and head to fire wall grounding conductor.

Install a ground loop from negative battery terminal picking up orange box, voltage regulator, alternator case attached by one each of their mounting screws. This will put all these devices at the same potential, eliminating any voltage drop in the ground side of the circuit.
