turn it over
When I connect it to a 25 amp P.S. It puts the P.S. into
protection How
do you know which is pos. or neg. on the dynamotor? I
wanted to run a
274n transmitter with out building a P.S. thanks 73

I am not an expert on dynamotors but this doesn't sound
right. A dynamotor is a motor connected to a generator. The
load on the motor should reflect the load on the generator
so that when the generator is running open circuit the motor
should not draw much current. Make sure the bearings are not
seized, that is that the shaft turns easily (if you can get
to it). Its possible either the motor or generator windings
are shorted.
