Hello, I’m new here and have been scouring the forums for an answer. I recently purchased a wash and I’m doing an update on it.
I’ve updated all the meter boxes and ran new wire to the pump stands, my problem is the voltage coming out of the transformers is like 10v on one leg and like 10 on the neutral. It’s a 120v/220v 100va transformer and I’m pulling a 110 leg off the contactor for the primary side and a common ground, voltage from contactor is 120v. Now these are old parts and this is the first pump/bay I am working on.. sooo..
I suspected it was just the transformer but what I have done is, check the other transformers on other bays and they will put out 24v. I then remove the transformer, put it on the pump im updating and it seems fine at first, then soon after I check my voltages, I double check and it’s got wonky voltages on both legs again. These are simple transformers, old as can be, but 2 wires coming in, 2 going out, I am putting grounds on both a sides.. any ideas as to what could cause these seemingly good transformers to crap out when I swap.. I believe I am hooking up correctly. Primary to 1 leg of the 3 phase and a ground… thanks in advance
