properly at their solenoid terminals (Figure right).
E) ENSURE the solenoids and their terminals show no signs of rust or
corrosion!
F) Set your CALIBRATED volt meter to read RESISTANCE (Ω).
G) To avoid error, one valve at a time, unplug both wires from its solenoid
terminals and, Figure right, measure resistance (Ω) BETWEEN the
terminals. Between 40 and 100 Ω?
Between 40 and 100 Ω! Plug the wires back into the solenoid
