I recently purchased a used 2007 RS Outback. The electric water heater does not work. The 12v relay works perfectly. When the circuit breaker (115 V AC) is on there is no voltage at the hot water heater. I used my ohm meter and there is no continuity between the circuit breaker and the water heater. It is as if there is a cutoff or on/off switch between the breaker and the hot water heater. I have looked everywhere for some kind of switch. Any help or suggestions would be greatly appreciated.
