49 8n 12v system, with new 6v coil, points, condenser, plugs, wires and Napa/sparex ballast resistor. Tractor started and ran great, then over a period of a couple days became harder to start until it wouldn?t start. Found no voltage on the downstream side of ballast resistor; looks like some arcing went on and the element is broken. I don?t want to put another new ballast resistor in until I know what caused failure of this one. Any thoughts?
Thanks in advance.
