I've confirmed that the water level switch is working properly, But when I disconnect the two leads going to the valve, I don't measure any voltage across them when the valve should be ON. But I don't know what I'm supposed to get - AC or DC, and what voltage. I assume it's 110V AC, but don't know for sure.
Of course this is a totally mechanical device which is controlled by a massive timer/switch box which I assume has internal cams that cycle things on and off. The valve should be turned on at least three times during the total cycle, but doesn't turn on at all.
So, before I try to take the timer apart, I'd like to be sure it isn't the inlet valve. As a test, can I carefully power up the valve with 110V AC just to make sure it works? I measure about 600 ohms across the valve coil, so I assume it's good, but need to make sure.
Any suggestions would be appreciated.
