Default Re: Generator output

3rd brush is not set-and-forget. Adjust low for high-speed driving, high for low-speed start/stop or night driving. After starting. the ammeter should drop to 1-2 amps after the battery recovers from the starting discharge

If the coil is wired according to the electrical drawing, its current is added to the battery charge reading. Ford issued a service bulletin to move the coil connection to the generator side of the junction box, excluding it from the ammeter. Best I can tell, the drawing did not reflect the change until 1932, after the model A run.
