Default Re: Motorola 251 8 Track Motor Resistor Burn Out!

The 1000mF must be a 1,000µF (micro Farad).

When you say live I guess you mean battery live as against mains live because I think this is a car unit.

Sounds like something is breaking down/shorting down, maybe after it has heated up. If you have a Megger suggest you check the motor circuit isolation resistance to earth, starting with the lowest voltage setting on the Megger, with 1,000uF disconnected.
