I have a one year old APUREM and PLC1400. The Power On light is on, but no display or any other indicator lights. I wanted to test the chlorine generator Power Interface Board. I have an old aquapure manual that shows how to test front and back boards from older models, but need to know how to use the "test points" on this PCB. It is part number R0467600. FYI, I recently had a lightning strike and think it may have zapped something. thanks in advance for any help troubleshooting this.
