Re: generator hook up
That would be a Chrysler, electric start, battery ignition with two coils correct?
On most Chryslers as delivered from the factory, there are no wires in the dash related to charging the battery. The whole battery charging circuit is contained within the engine.
Two wires will come from the alternating current alternator to the rectifier/regulator. Rectifier/regulator converts A/C to D/C at about 14 volts. The red wire from the rectifier goes down into the wire loom, and connects to the terminal board and then to the circuit breaker. This will be the one with two wires crimped onto one connector. The other terminal on the circuit breaker has a red wire connecting to the battery side of the starter solenoid. SO; voltage goes down through the circuit breaker to the battery wire, charging the battery.
When the alternator is not working, voltage flows directly from the battery through the red wire and the circuit breaker to supply power to the terminal board. The red wire in the cable that goes to the dash supplies power to the ignition switch and engine accessories. Any wires you have free under the dash are probably power sources or unused. For example: purple wire is not used.
If you have replaced the voltage regulator/rectifier and the battery is still not charging, since you had "wicked sparking" check the circuit breaker and check all red wires to see whether they have burned though, especially the one from the rectifier to the terminal board. It is not inconceivable that you may have also damaged the alternator windings and the alternator is not producing power. So. using a voltmeter, with the wires disconnected from the rectifier, check for resistance on the alternator windings. There should be some--not a lot though--I forget the spec though. Infinite resistance indicates an open circuit and melted or broken wires in the stator.
"wicked" is usually a regional term. Are you from Mass.?
