ok so no mode selection.
lets clarify something then, which controller does it have in it?
THE ev100LX or the sem sx controller?
both can be checked and set using ge sentry or a handset.
and does it have a premium display panel on it?
the difference between standard and premium is the premium is interactive with more options displayed along with performance modes, and the standard has just basic display functions. One will have 5 buttons on it, the standard will not, it will be just a basic display.
also the hydraulic, is that contactor controlled? or is there a 2nd controller for that mounted beside the traction controller? also another tell tell sign if it's premium or not.
Sounds like you have just a standard display.

now if you want to test that PCB control board on the hyd valve here is the test point layout:
TP1 battery neg P1-1 (P1 terminal)
TP2 battery pos P1-5
TP3 first function optical switch (lift) P1-6
TP4 first function optical switch (fast lift, not used with single speed lift pump) P1-7
TP5 second function optical switch (tilt) P1-8
TP6 third function optical switch (auxiliary#1) P1-9
TP7 fourth function optical switch (auxiliary #2) P1-10

Best i can tell from the table on testing the board your readings should be either greater than 3v when the switch is closed or less than 3v when it is opened.
