this should be simple for you guys, 78300d quit starting, from the #5 plug to #4 plug the resistor wire glows red, same for #4 to #3, the remaining resistor wires do not glow red, but they do get hot. i pulled plugs 1,2,&3 and they look ok, no broken loop, and resistance testing seems to indicate that they are ok. Bad resistor wire ? plugs bad anyway ?, any suggestions would be appreciated.
