The ozone doesn't plug into the pack per say , I believe it's connected to the circ pump by a splitter , here is the pack - socket one is pump 1 , socket 2 is pump 2 and then 3 was the circ pump but gecko is saying it should be 4 , regardless it doesn't work on either , audio was plugged into di port. Moved circ pump to di port and still nothing . No lights , radio , ozone or circ.
I do have multimeter and know how to use it . We are getting power to the circ pump
However I can't seem to have enough room to actually test to port itself I even took the sleeves of the meter but they still aren't long enough .
I have that power supply right in the front I will test the wires as you stated
