0 There is a breaker where the negative battery cable connects. There is also a thermal switch in the top of the transformer. Follow the black wire that connects from the timer to the upper corner of the transformer. In the hole is a Klixon thermal switch. Check the continuity of the two wires going into the hole. If there is no continuity, the thermal switch has opened. You can slide it out with a pair of needlenose. If there is continuity, it means that your transformer is most likely bad.
