txs,

Your description needs some more info. Are you capable of testing the wires for voltage. Do you know the power source(on/off switch or breaker) of the larger wires since they are coming out of the wall. The source voltage will be 120V and the smaller wires will be 24V after leaving the controllers transformer. I assume the controller was inside somewhere. If you are not familiar with electrical troubleshooting, I would recommend you have a landscaper/irrigation set your system up. You will probably get a warranty with effort as well. JMHO Aloha

Thanks for your response. I was hoping there was a "standard" color coding for the wires that would allow me to solve my problem more quickly.

I did not know where most of the valves were in the yard (1 acre) so that added to the complexity.

In the end, through a combination of an in-ground wire locator (the type used typically for locating buried pet fences) and a wire sensing unit (transmitter attached to the wire and a hand held unit that make a sound when the transmitted wire is found on the other end) I was able to label all wires, hook them up to a controller and get the system running.

The original installer did not use a consistent color coding system for their install. It took several hours to complete this project.

txs,

If you only took a couple hours you did very well. Aloha
