RT-3 suddenly stops

[ubxf]

Hello,
My RT3 was working well and after 1.5 hours the generator stopped . When i tried to restart the Start motor was ok but when i went to run it stopped. I waited a couple of hours and it started fine but after 15 min it stopped again (record stop style pitch bend down)
The shaft spins freely and when the generator is running there aren't any squeaks. Do you guys think that the run motor is dying or is it oil related or ?
Many thanks

Typically Run Motors either work or they don't. If the organ is properly oiled...I'd put my money on a failing Run Switch.
