Yesterday I opened the Phoenix motor and tested the armature, probing the commutator directly. I was surprised to see it ohmed out at 0.7 ohms! That means, at least in theory, the startup draw of the motor on 12 volts would be a bit more than 17 amps! No wonder the 5 amp fuses popped so quickly!

I am falling back to using the JK Product M20 Hawk DD motor, at least for now. Tested without disassembly it ohms out at about 6 ohms. That would give it a startup draw of 2 amps -- possibly more, but hopefully less than 5 amps.

To be continued...
