We have an Intellicenter with the SCG power supply built-in. The Pentair IC60 died so I bought a Splash IRCF60 and it was working fine until recently. I won't come on for 30 min - 1hr after pump starts. No LEDs flashing at all. There may be some correlation with colder temps and longer delay, not sure. It has occasionally also gone dead mid-day, temporarily then comes on again. I cleaned it, changed the flow switch, no difference. It is wired on the load side, same relay as VST pump. My surge board (521593) green LED D2 is on.
I took a variety of voltage readings and am totally baffled by some of what I found!
The 240Vac going to the transformer is fine and the J8-J9 reading is 30.7Vac, with or without the SCG connected (but not working). Not sure if that's large enough output.
Between JP1 RED-BLK on the surge board: 40.9Vdc (SCG working ok) and 27.1Vdc (SCG disconnected). Seems backwards and it's not a record keeping error.
Just for kicks I measured the AC voltage between RED-BLK: 89.2Vac (SCG working ok) and 58.8Vac (SCG disconnected)! Not mVac.
Also some big AC readings on the DT+/- com lines, which are not used in this knock-off cell.
Now I'm second guessing whether the original Pentair cell is truly dead or if there's something wrong with my surge PCB. Can't recall if the Pentair was dead or just had a red LED on.
The two transformers are very hot to the touch. A failing bridge rectifier could account for some of the symptoms but maybe not all. The bridge's 4 solder pads are discolored, so either re-worked or overheating.
Maybe some of the filter caps have aged in the brutal heat here in southern NV.
I'd like to do something more intelligent than replace a bunch of part$. I'm comfortable replacing the bridge if the pads can hold up.
Any insight is much appreciated, thanks!
