Troubleshooting for an open ciruit

[electricpete]

Troubleshooting for an open ciruit do continuity checks on the primary and secondary circuits (as much of the circuit as possible). Try banging the equipment a little to see if you can cause an open circuit.

Is there perhaps two different secondary windings on the same PT? Maybe that explains why one motor tripped and not the other?

I'm not sure why it showed up as a standalone post (most likely operator error!). Does anyone know how to delete it?
