So I'm working on a Gottlieb Jet Spin and the voltage at the score motor is only about 20v voltage at the fuse it is 25v. The score motor will try to run but just sits there and buzzes if I help it along it will spin but slower than it normally would. It looks as though the voltage travels through about 12 relays before getting to the score motor jack if I'm reading the schematics correctly maybe im reading it backwards. My plan was to check voltage along the path to see where I'm loosing the 4-5 volts. Not sure if anone has a easier method. The score motor ohms out correctly so i dont think that is the issue.
Thanks,
Joe
