I have an Intermatic ML 200RT transformer. I have power through the transformer to the terminals. However, when I connect the wires, the terminals are no longer hot. I'm checking the current with a meter. Not sure why I'm loosing power?
Are you sure that bare ends or other parts of the wires don't touch one another where they should not further downstream causing a short circuit?
The good conscientious technician or serviceperson will carry extra oils and lubricants in case the new pump did not come with oil or the oil was accidentally spilled, so the service call can be completed without an extra visit.
