The installation of a bulb in that circuit makes the light glow when the power is trying to go backwards, but the current after that bulb isn't enough to fire the ignition coil. Another fix can be a relay, as you saw in Summit catalog. Either one, if wired corectly will fix your problem.
so then i need to put in this "idiot light"? if you have any specifics i would really appreciate it. i.e. which wire to tap into or what kind of light

would the problem stop if i temporarily unplugged the second charging wire? im gonna try that right now. thanx for the help.
