I have a rainbird ESP-6TM system.

There are 6 zones and the system will work fine where it will cycle through zones 1, 2, 3 but then it wont continue to zone 4,5,6.

There is no mechanical issue as I can manually turn on the valves for the zones 4,5,6 and they will work fine.

There seems to be some electrical issue in the valve box for zone 3 where sometimes if I jiggle the wires a bit, the zone 4 will start and the system will cycle through fine.

But the problem returns the next time.

The problem seems to have started after the valve box for zone 3 started leaking.

I would really appreciate some help in trying to DIY and fix this issue.

I had one guy take a look and he was asking for $600 for the problem.
