Wave 50 will not lower - Technical Troubleshooting discussion in Forkliftaction's forums

Crown WAV50-118:
Wave 50 will not lower

Hello
I have big problem. Wave 50-118 will not lower sometimes. The platform locks at different heights.
I have already exchanged:
-solenoid valve
-velocity fuse

I checked connections and buttons. Everything is ok :(

The only hint is that it always happens at low battery voltage.
Does anyone know what is the lowest coil voltage on the solenoid which the solenoid valve will open ?

If you can still manually lower the platform after it stops, then the cylinder is ok. Check resistance through the lowering switch. If there is 1 ohm or more, that will give you lower-than-battery volts causing the coil not to work. Pretty sure under 20v....it will not always work

No Codes :( I'm thinking maybe there is a problem with piston and spring inside the lift cylinder ??
