Hello,
Since you guys are offering free advice, how do you test an obsolete DC motor?

I've got an old motor with brushes and no name tag. I know the motor runs off of 240 volts DC. It's not making any attempt to move. Looking for a methodical troubleshooting procedure for a motor with unknown specs. I know this sounds like a strange question, but I'm looking for advice on the best method of testing since I'm fairly certain this is a vintage obsolete DC motor and I may be looking at upgrading the motor and control if I can't get this going.
