Hi Mark
It might pay to check with someone using the same regulator. Might not make much difference. If the regulator controls field current in theory only about 1.5amps at 12v instead of 3 amps need be supplied to the field so at present the field can presumably be fully magnetised when the output is only about 5 volts as from the original 3rd brush.
Hi Jon E
Nope. Just inexpensive voltage monitors if 12v supply available. I use one calibrated to monitor my battery charger. Can be observed at a glance. (many chargers have built in) Seem to recall about L4 equiv here.
Particulalrly without a regulator, max output is most efficently limited by the 3rd brush. There is seldom cause to alter the summer rate but the fixed resistor can be substituted or augmented by an external one to suit. For traffic driving use Winter.
