Ok where to start...... If the power head was truely shorted, the current would have exceeded the rating of the over current device, usually being the circuit breaker, therefore the breaker would trip and there could be no current.
Current can not flow or exist unless it has a path to flow on, therefore current cannot be waiting in the tank. Current is the result of voltage on electric circuit.
