Valve Doesn't Open--Possible Break/Nick in Wire

I had someone install a new valve and it is getting only about 17 ohms to the valve from the control box--not enough electrical current to open the valve. The gentleman said there is probably a nick or previous break in the wire that was repaired. I did have some landscaping work around where the wire passes thru. The question is: is there a way I can personally detect the break in the wire and hopefully repair it without hiring a professional...some Radio Shack item?



Thanks

There's something fishy here. Ohms and current are not the same thing. A bad splice would give you a high reading not a low reading. Ohms is resistance. A bad splice would give you more resistance.

Double check your readings. Ohms, Amps, Volts.

Also test the solenoid itself. Could be a defect.

Before you spend all that time looking for a bad splice I'd confirm there is a bad wire.

If you have a valve right next to the new one switch the wires around and see what happens.
