Error 4:180

Bt Industries RRE200CC

Error code 4:180. Service Manual Troubleshooting - Step 1) Is to verify valve Q2 opens. In service mode pulling back on the reach lever should extend the main lift but does not! Pump runs but no main lift.
CID diagnostic (4) pos. 7&8 inputs change when B19 is rotated by hand.
Do I pursue the Q2 no lift issue, or go after the height indicator, which seems to be working.

Also upon start-up CID display shows a box with a question mark ? and 2 arrows pointing up. Turns out that's a big clue!
Apparently the 2 magnetic sensors on the same bracket as B19 at the top of the mast were faulty and "confused" the lift from having any idea where the mast was in height.
It was doing all sorts of "funky" things but after changing the whole B19 and mag sensor assembly it's happy as ****!!
As usual - "You find success on the far side of failure!!"
