A while
back you mentioned
the need for three batteries
to test these old thruster motors. Even though these are
designed for 36 VDC
nominal, it would be a perfectly good test and safer to
connect to a single 12 VDC
car battery. It would run at less RPM and determine if the
motor is still good. The DC motor on my boat is designed
for 120 VDC
nominal. When I got the motor, I tested it with one of my
12 VDC batteries to
confirm that is was working and the rotation direction as a
function of polarity.
