TROUBLESHOOTING / 93
The RED wire should read battery voltage (+12V) and the BRN wire
should read a voltage equal to a percentage of +12V determined by PWM
SAT value entered under LIQUID CONFIGURATION (F5) (i.e. If PWM
SAT is 90, then a reading of +10.8V –12 x .9 = 10.8 should be present).
Check voltage readings at the pump or solenoid coil on the valve. The
RED wire supplies the PWM voltage signal to the pump or solenoid coil,
while the BLK wire is signal ground. Voltage reading should be equal to
those above.
2. If voltages are present but sprayer does not spray, the pump, solenoid
coil, hydraulic valve, or hydraulic flow may be faulty.If voltages are not
present, check wiring harnesses for cuts or shorts, then replace the
liquid valve driver. If this does not solve problem, replace the console.
