It’s been a while, I’ll need to pop the top off of mine. Have a swim meet to go too. Can it wait until later today?
First, confirm your wiring configuration.I remember the 220v version had 4 positions on the input side of the transformer. Going left to right I designate them wire position 1,2,3,4
If I recall there is a wire from the plug going to position 1 and 4. A jumper wire bridges positions 2 and 3
Correct?
