Two Valves - One Zone - Power Short

[duke69111]

Hi All,

I am having some problems with a sprinkler system. My system is a

Nelson 8300 Jr. - Control Box with 6 Zones

I have two valves for zone 1 in my system. One valve controls half of my heads and the other valve controls the other half of zone 1. I have the ground wire spliced/connected with the power wire from both valves, and the On/Off wire spliced/connected to the remaining wire from each valve. When they are connected this way the zone shuts off after about 2-3 minutes and the power short icon on the control box is on.

If I seperate the two valves from the brown wire, and hook the brown wire to either one of the two valves by themselves, it works fine and runs the full time.

I have attached a simple sketch of what I have.

Any help would be appreciated and thanks in advance.
