spray switch once, measure voltage between water
spray timer switch terminal 2, 5 inlet wires GL and
chassis ground.
Standard voltage : 12 V
(2) when starter switch is ON and depress F-R lever water
spray switch once, measure voltage between water
spray timer switch terminal 1 outlet wire GB and chassis
ground.
