Greetings
‘I’m sorry to say but that motor is 40+ years old.
you can try to replace the resistors. I would recommend upgrading to a new motor. Get into the Oracle website and view all their upgrades, or call them. Great people to deal with.
Besides the motor the only other thing to replace would be the truss pad. As you know Oracle makes rebuild kits for the suspension system.
I had a MK 2 for 40 years and the motor (pancake motor DC) finally passed away in 2022. I decided my best option was to trade in my MK 2 for a new MK 6. Wonderful TT.
Sorry I can’t help you more.
