The problem is that the resistor limited current low enough not to blow the fuse, but got so hot that it started a fire.
I've already decided I'm designing a circuit board to fit in place of both relays, and use PWM to do low speed without a resistor. I'll probably have a couple extra to sell, should be cheap.
