1. Check if the “B” solenoid valve coil (FIGS.

78-1 and 78-2) (located in the pump

box) is getting power. Connect voltmeter

to terminal-1 and terminal-2 of the coil.

Activate the DOWN toggle switch.

Correct indication is +11 to +12.6 volts

dc. If the voltmeter does not indicate +11

to +12.6 volts dc, check control switch

and wiring to “B” solenoid valve (refer

to ELECTRICAL SYSTEM DIAGRAMS

section). Replace faulty wiring or control

switch as required. If the voltmeter

indicates +11 to +12.6 volts dc and valve

still does not operate, replace the valve.

NOTE: For dual pump system, check secondary pump and motor ﬁ rst.

NOTE: Numbers for the electrical terminals shown in the illustration are not

stamped on valve coil. Numbers shown are for reference only.
