"Checked my wiring from beginning to end for continuity issues etc."

Fairlane, I hear members of the local Model A club and occasionally others make the same comment. You might already know this, but just in case you or someone else doesn't:

Continuity is checked with an ohm meter. The ohm meter passes milliamps through the portion of a circuit bounded by the positions of the two test probes. Using an ohm meter, the circuit may test good when it is not capable of passing a legitimate load test. Milliamps are .000s (thousandths of one amp) In operation, the ignition on the Model A will draw ~ 4 amps, or ~ 4000 milliamps.

"Voltage drop" test methods are used to determine the quality of a circuit. You can find a series of voltage drop test procedures that will verify that your car's wiring is in good shape, marginal, or poor condition in Les Andrew's blue book, "Troubleshooting and Diagnosis", Chapter II.
