Pfenning said:Doc, I did just like you asked and the reading was 2.3?? mega ohms. My meter is autoranging. I assume this means the OT is fine and I have another issue.
2.3 megohms is essentially open. Not good. Should be in the hundreds of ohms. Since you have disconnected from the circuit you know the open is not at the terminal strip where the red and blue leads connect. So the open must be at the end of the leads where they connect to the coil inside the transformer, or in the coil itself. Perhaps a lead was pulled on and that damaged the connection? Has this transformer ever been used before?
