Hi, I recently tried to replaced my mothers timer on her underground
sprinkler system. For some reason its not working. The zones don't recognize
the new clock. The new clock is 24volt. I think that is where the problem
is. Her system is about 30 years old. Did they use a different voltage in
the past? Steven

Sort've doubt the voltage has changed much. The solenoids on the valves might
require more current than your present timer / wall wart is capable of
supplying. I'd try simplifying the problem, and just try jumpering the wall
wart directly to one of the valves to see if it actuates. Oh, and to cover the
obvious -- make sure that the water is actually turned on to the system -- if
the system had been winterized, the water is probably still shut off.

Check if you get 24V at the solenoid. If its good, then the solenoid
valves might be stuck. If you don't get 24V at the solenoid, but you
get it at the timer, you have a break in the wire someplace.

Steven-

I just recently went through the same thing at my mom's house.

I replaced an older sprinkler timer with a Toro 8 station timer.
The sprinkler valves & solinoids are ~30 years old .
(I installed them personally when I was a kid)

They work fine with the new controller. When you say they "don't
work", do you mean in manual mode or in sutomatic mode?

The Toro unit requires that you press the manual start button twice to
operate.

Solinoids are pretty much unchanged for the past 30 years or so.

All the systems (5 total) I have installed or repaired in the last 30
years work fine with the currently avavilable Toro timer.

cheers
Bob

The old clock works in the manual mode, The mechanical timer stopped
working, With the new clock, The system won't go on manually or in
automatic. Steven
