If the system USED to work, nothing has happened that likely damaged the controller or wiring, and the rain sensor is wireless, the most likely point for the breakdown would be the communications between the sensor and the unit that connects to the controller. If so, then re-wiring the system won't solve the problem.

The simplest and cheapest way to attempt a quick fix would be try replacing all batteries (are there batteries in the base unit?).

After that, double checking the bypass setting as others have mentioned.

Finally, you might want to attempt to reprogram the transmitter address. The instructions say you shouldn't have to unless one of the parts was replaced. Here's some instructions I found with a Google search.,2005.pdf

RE: check the batteriea

If they are going bad or are dead, the sensor will not work right.
call me dumb but they have factory batteries that are 12 years.

There are open circuit and closed circuit rain sensors. Follow the wiring advice of Lush 96 and add a small jumper wire between the two rain sensor terms as aquatech wrote. The rainsensor does nothing more then cut the electrical loop from the timer to the valves. When the sensor is activated, the light will still come on. The timer will continue to run as it would, but no power is sent to the valves. Most rain sensors have a battery life of 5 years, so consider changing the batteries also. You can simulate the rain sensor activation by using a ladder to access the sensor and gently click and hold down on the top of it. Watch a nearby zone go up and down. The timer will also have to run in the bypass mode from here out.

If the rain sensor doesnt use the sensor terminals you have to make sure that there is a jumper from 1 terminal to the other.

funny this is up here i have the same problem...i have a icc controler and a wireless rain click also and it came on last night after it got done raining and the light was red but the controller still let the zones come on and the switch was not in the by-pass position so i haven't had time to look at it yet.. i will try what you suggest lush tks

if its a pro-c controller or icc, install it WITHOUT using the snsor terminals. i know this from experience. my company went crazy trying to figure this out. so we had a hunter rep come out and basically tell us that they pretty much screwed up with the rain sensor terminals. wire it this way...........both yellows to the 2 ac into the common terminal on the timer......then twist your common wire with the white together and wire nut it. orange is still nothing. remember you need to go where the actuall rain sensor is installed and push the little pin down behind the cup and hold it for 5 seconds to reset the sensor anytime you cut power off to the timer. wire it the way i have explained. it will work.

Have you made sure the WRC control box is not in bypass mode?? If you push the button on the receiver, it will turn the light red and bypass the sensor.

When you say the system still comes on, are you referring to it as automatically, or manually. The controller will bypass any sensor information if you are running it in the manual mode. If you are running in the auto the sensor should interrupt any watering at that point.
