Hi all, first post, great site! I have an Aquabot turbo remote control robotic pool vacuum that has performed flawlessly for 6 years. When I try to run it now, with the black button on the power supply it will start momentarily. As soon as I let go of the button ( which should start a 7 hour timer cycle ) , the unit stops working. Do you think I need a new power supply? The fuse is good, and the outlet is good. Any one have any ideas?
