Scuba Frog,
Thank you for the reply. I pulled the 31.5V off the sticker on the transformer. My fault for thinking it was DC. I may have other issues that led to the transformer failing. I had issue with the timer years ago and eliminated it from the circuit. This past season the power supply started to blow fuses after the Aquabot would run for some time. After replacing the fuse several times it started to blow fuses even if the Aquabot was not plugged in to it. I eliminated the power supply wires and ran fused AC directly to the transformer...it blew the fuse right away. So I will dig deeper with that power supply when I get a chance, but I sure thought that this told me that the transformer was bad.
I just picked up a used Aquabot power supply that I was told was in good working order. I tested it on DC (silly me) and thought it was bad. Well I just tested it and it measures 34 V AC when on. I put the unit in water, turned on the power supply and no dice.
I will start to work on the unit testing for voltage along the wire path, checking for corrosion and report back.
Are there any other common points of failure?
Thank you in advance!
Robert
