Bob,
You will have to probe the connector in the Aquarium. Find it, and put a DVM on the Black and White (I think) anyway the signal wires. Watch the voltage, it should flutter around the .5V mark .2-.9V. If it doesn't check your splice.
I believe you have a 3 wire unit, check the heater wire to make certain that it is giving 12V to the element at startup. I think the ECU drops the voltage once operating temp is reached.
Hope this helps, let us know.
