Was hoping someone might have seen this, or can help troubleshoot. I have an old dolphin diagnostic, I think its around 10 years old. Replaced the power supply, and tracks a couple years ago. Tonight I pulled it out of the pool, clean the bag and put it back in the pool, pressed the power switch and the light came on, but after maybe 3-5 seconds it flipped the switch to off. I waited about 10 minutes, tried again the same thing happened...light comes on when pressing the power button but after 3-5 seconds flips the switch back to the off position. Any help would be greatly appreciated.
