Single ballast has the run and start wires on one side for points. Electronic has the dual ballast one wire on each side. Should have stated that earlier. Just FYI on the single ballast it should be .5-.6 ohms.
Doubt it it runs if it was blown out no start. Easy check should be .5-.6ohms across it. if it is the right one. Bad switch can send the vdc to the ballast in start and the circuit is good. Yes dual ballast can do that one side gone. Just FYI
69 has a single ballast if it is running it is good. Try to troubleshoot the wiring into and out of the switch before changing it 69 is a one year only $$$ switch
If it is a new parts store points and condenser.........Start there the points have terrible spring tension and the cond are hit or miss, usually act up in a heat cycle.
This is the last call after Jun 1 till The end of July they will be all packed up If something is needed and you will be at Carlisle I will try to put it on the side. Thanks all.
