I have a Nichiyu FBRF20-75-950MFCSSF and it has the following issue.
after the key is turned on the lift function will operate for approx 3 seconds and then stop. All other hydraulic functions work no problems. After this occurs the lowering will still operate as normal.
This is the only issue this unit has all fwd rev functions etc are working correctly.
All boards have been checked in another unit and they have no issues.

Can anyone help?? and also does anyone have a wiring diagram for this unit.
