A way back problem

Vinny Kreyling · 12/03/2020, 09:33 AM

Have my original Aquacontroller II running everything.

For some time now it flashes between the normal screen & Battery Low.
Even does this with a new battery installed. Is there something I can do to remedy it? The battery connection receptacle has split if it means anything.

I still use an AquaController 2 as well. It has been more reliable than my Apex. Glad I hung on to my AC3 as well. First try another batter. Check the voltage to make sure it is good. If that doesn’t fix it, I would unplug it, remove the battery and cut the wires close to the connector and wire in a new connector. If you good with a solder iron you could remove the wires at the PC board and solder on a new connector. They do seem to run those batteries down fast. Good luck!

Had to wait for the battery connector to finally arrive after a big delay.
Opened the controller but a little too much for me to get to the wires on the board.
Soldered connector wires & am back in business.
Never would have thought.
Thanks laverda.
