396-3815Y1 SureFire PumpRight for Raven RCM 51 Revised 01/16/2018
Hydraulic Pump Will Not Turn
Turn hydraulics off, go to the SureFire PWM valve and use the manual override (red knob) on top of
the electric coil to manually open the valve (Manual Override UP = valve fully open). There may be
dirt in here that needs to be cleaned out before you can turn and raise the override. Turn hydraulics
on at a low flow only as the valve is 100% open. If pump does not turn, try hydraulic lever in
opposite direction. Does the pump turn? If it turns, your problem is electric / electronic. If the pump
still does not turn, you have a hydraulic problem.
Electric / Electronic Problem
1. Close manual override (lock down)
2. Go to Diagnostics, Calibrate PWM Limits Test to in-
vestigate this issue (this is a place where you can turn
the pump on).
3. Verify hydraulics are on.
4. Start test. Hold down “+” button for a few seconds. A
single tap of this button produces a very small change in
signal to the valve, so you must hold it.
5. Take a metal object and hold it next to the coil. If the coil
is working, you will feel the magnetic pull.
6. If no magnetic force is felt, disconnect the PWM valve
connector and check voltage. You will need 6-12 volts to
get hydraulic valve to open.
7. If 6-12 volts is not present, check harnesses and review
control valve type setup.
8. Go back to the 12-pin connector that plugs into the Pump
harness. Check voltage between pins 5 & 6.
9. At 35-pin connector on ECU, PR 1 PWM—pins 23 & 35;
PR 2 PWM—pins 13 & 24). Contact SureFire for further
assistance.
10. You can remove the electromagnetic solenoid with pro-
portional valve to see if the valve moves when a PWM
signal is sent to it.

Hydraulics Problem
1. Leave the manual override open on the
SureFire valve.
2. Check the hose routings. The “P” port on the
SureFire valve should hook to pressure. The
“T” port is the return that should flow back to
the tractor.
3. Try hoses in a different hydraulic remote.
Inspect hydraulic connectors for damage or
restrictions.
Hydraulic Manual Override
Down - Normal Operation
Up - Override, valve 100% open
The Section Test is another place to run the system. Or,
enter a Test Speed and run the system in Manual Mode
from the Run Screen.
Tests > Nozzle Flow Check is a good screen to try a
Speed and Target Rate to see if it will lock on to a rate.
When testing with water, the pressure will be a lot less
than it will be when using a fertilizer product.
You can also enter a Test Speed and run the system in
Auto Mode from the Run Screen.
