14. Remain at full throttle and max out the lift valve.
There should be a PEAK pressure of 1100-1200
PSI. See figure 6.
NOTE: Only hold the lift valve for a short amount
of time. Record the reading and release the lift
valve lever as quick as possible.
IMPORTANT: System pressure will increase with the
actuation of the power steering and/or deck lift.
If the pressure readings are not meeting the specifica-
tions, the charge pump is faulty.
If the pressure readings are meeting specifications,
the charge pump is not faulty and the mechanical
system must be checked.
