By the way, in case you weren't aware, to turn on a circuit breaker, you don't just push the handle to ON. You must first push the handle all the way to OFF, then back to ON. More than one person has been fooled by thinking they had turned on a breaker, when in fact they had not.
Onward. With shore power connected, the breaker confirmed ON, and the switch on the water heater turned on, measure the voltage on the element's terminals as Bob suggested. Expect to find around 110-120VAC.
If you find the correct voltage, but it still doesn't heat, then disconnect shore power from the TM, disconnect both wires from the heating element terminals, set your multimeter to Ohms X 1, put the multimeter probes into the multimeter sockets labelled "ohms" or "resistance", and touch the other ends of the probes to the heating element terminals. You should see a resistance of a very fews ohms. Something on the order of 10 ohms. If the reading is very high (or infinite), then the element is bad (open).
