Found a wire pulled out from the return solonoid. Coincidental it happened same time as a pipe burst, why I never took any time to investigate the wiring.Are you short of oil in the resevoir. I've seen that happen on a different system after a burst, on that particular one the bottom of the sight glas wasnt enough.
I'm not familiar witj the storth system, but a lot of systems has one solenoid valve on each ram that prevents them going forward and an automatic reversing valve on the hudraulic unit that reverses the oil flow when a certain pressure is reached. If you have enough oil in there and other passages work I'd be looking at the solenoid valve.
