Any diesel mechanics in here? I have a Cat 246 Skid steer. And when I plug in the block heater....it trips the circuit breaker. At first I thought the cord was bad - so I replaced the cord. (the cord that plugs TO THE ELEMENT, not the extension cord) With the new cord, it still tripped the circuit, so I got a new element. (It is the element that goes in a freeze plug hole) And with the new element....it still trips the circuit. I have a heavy duty extension cord, and it is not long at all. Why is the circuit breaker tripping? Could it be that part of the element is making contact with the head and is grounding out? (the element has a rubber seal, to keep coolant from seeping, and I would assume to ground the element) Any idea what's goin on here?
