Some basics on Williams engines; one they use DC can motors, so AC getting to them will make them get hot quickly. The circuit boards transform AC into usable(or pulsating DC) DC by means of electronic parts, and if one of those parts fails and lets some AC pass through then the DC can motors will heat up.
There is more chance that a circuit board goes bad then the can motor.
