Thanks for having this great resource.
I have a Dig-220 that was installed in 2005. Last year and this year our SWG was constantly running at 100% using an SC-48 for 12 to 14 hours/day but this year my pool had like (.1) FC. And THEN we started to get the "low amps" message. I did everything recommend and then called AutoPilot tech support. Though it didn't look that bad, we all agreed that the cell was failing. I bought a new RC-52 to replace it. That did the trick except when I installed it, I forgot to bump down the % of output so after about a week we had too much chlorine. To get the levels down, I shut the SWG off. After a few days when things got normal, I turned it back on, exectp now it said "check cell - low amps". Testing showed 8v and .2 amps. Back on the phone with AutoPilot; after basic testing and checking, determined problem to be bad power board. I bought and installed new power board.
New power board now shows 0v and .2amps. Back on phone with Autopilot. Using DMM, we tested and verified everything we could including swapping sc-48 with RC-52 back and forth. Tech is pointing to bad power board but was going to consult with someone else. I have not heard back from him yet. After the new power board was installed, for the first time that I've ever seen, the control board display went blank (while on the phone w/ AutoPilot). I had to power off/on unit to get it to display again. (It has now happend a couple more times as well.)
Does the control board affect the voltages being put out by the power board? Is it "likely" that I got a new power board that was DOA? Does the blank display indicate a bad control board even though the flashing light continues to flash?
I've now put the old power board back in place and have the same readings in boost mode at all power levels: 8v, 0.2amps.
Should I buy a new Control board or wait to speak w/ Autopilot again.
Thanks for your help with this.
