Thank you for the explanation. The field coil has resistance of 3.2k Ohm according to the parts list. That's a lot of wire at 32awg about 20,000 feet, so I am assuming back in the day wire was not as good as today's standards so probably had higher resistance? That's why I thought I'd go by weight instead of resistance, I can always add a 5w or even 10w (just to be safe) resistor in series to compensate for the resistance drop, or is it a bad idea? Thanks,
