While this may not be the typical failure mode for HID modules (been mentioned already that they tend to short internal to the voltage coil), I've seen enough power supplies short back to the input via regulating components, feedback loops, and even shorted windings to know that what I stated is quite possible. Knowing this, I cannot consciously give advice to anyone to  preclude their own safety.
