Guys, at the tail end of a frustrating summer, I thought I had beat this thing into submission. I’ve been through green pools, a new cell, and a new back board, and everything was looking ok. Now it’s giving me a 123 code again. Cell is clean. Ran the Jandy troubleshooting with my meter. The Troubleshooting PCB – Salinity came in at 3.2 instead of the acceptable range of 2.7 - 3.1, but the real trouble was cell voltage, which was only 12 instead of 30, and current, which was essentially 0 instead of 120mV. Any thoughts on where to go now? Is the back board bad? Front board? Thanks in advance.
