sherlock holmes and the water heater mystery

[made2care]

I believe the mystery might be solved. looked under the trailer right below the water heater and the flooring has been replaced, this explains why the 110 wires were not reconnected. the owner just went with the lp. Quite a few of you suggested this was the case!
two brown wires that went to the rocker switch are hanging, a black wire goes to the heating element.
here is my question? i connect the 110 white to the white on the water heater and the brown wire from the rocker switch to the black 110??

That sounds normal. Check for shorts on the heat element first, that may be why he unhooked it.

Use your VOM and do a resistance check of the heating element. It should show some resistance maybe 3 ohms or so I'm not sure. It certainly should not be 0 which indicates a direct short and it shouldn't be open indicating a burned out element. Now check the switch to be sure it works too. use yopur ohms scale just as a continuity check on switch. Now set the VOM to volts AC and check that you have ~120 volts at the romex when plugged into shore power. If yes hook up your element through the switch. If no 120 find out why.
