These charts are intended to be used as an aid in diagnosing problems on the V-68 Meyer Hydraulic Power Units. They are not a
substitute for factory training and experience. Be certain to read the General Information and Testing Tips sections before attempting
any troubleshooting.
TESTING TIPS
Many tests
do not require removing the Power Unit from the vehicle. However, more thorough testing can be done by using the Meyer
Test Stand which allows direct pressure and Amperage readings.
1. Use a screwdriver or other small tool to check for magnetism of solenoid coils (“S1,” “S2,” “S3,” “S5,” “S6” & “S7”). Place the tool
on the coil and have an assistant operate the switch. You should feel strong magnetic attraction.
2. Use a test light or volt meter to determine whether there is power at harness or Super-V controller.
3. When determining Amp draw of motor, always obtain the highest value possible, i.e., at maximum raise or angle with motor running.
4. The pump shaft of a good pump can be turned smoothly using two fingers. If it can’t be turned easily, the pump must be replaced.
6. Pump pressure can be measured at an angle hose (note pressure at full angle).
7.If hydraulic system is contaminated it is recommended that the hydraulic unit, power angling rams and hoses be drained and flushed
with M-2 flush fluid. The system should then be refilled with Meyer M-1 oil. See page 9.
