the resister will get warm. It takes that 6 volts and turns it into heat. If you calculate the power it has to dissappate, lets say the coil pulls 2 amps peak, the resistor is disippating (SP!?!?!?) 12 watts of heat to reduce the voltage. It should get warm.

As for the coil, I've never paid attention to mine, I'd imagine it could get a little warm. I'd say put a meter on the coils power wires, but unless your meter has a peak hold and can rsolve the frequency, it wont be accurate because its pulsating DC.
