someone moved those dip switches? oh boy :o/
code -01? code H?

ok first off...
- the code -01 is no kill switch (emergency cutoff aka:estop) input.
check the estop circuit
or it could be...
- the brakes not releasing or....
- open circuit between B+ and TB3 on control card.

But before you even check that lets get those dip switches in the right sequence, there are 2 dip switch components on the IC, one has 8 and the other has 3 switches in it.
We'll start with S1 (8 switches)
by factory default they are set as follows:
(note: if the switch is moved toward the indentation it is considered ON, away from indentation it is OFF.
1 (lift inhibit or lift cutout) = with inhibit option OFF, without ON
2 (2 or 3 stage mast) = 2 stage OFF, 3 stage ON
3 (full speed option @ 60") = with full speed ON, without OFF
4 (lowering deceleration) = with decel option ON, without OFF
5 (not used)
6 (throttle learn mode) = learn mode on ON, normal run mode OFF
7 (lift/lower learn mode) = learn mode on ON, normal run mode OFF
8 (2 speed lift) = 2 speed enabled ON, single speed OFF

Now for S2 (3 switches) these are for setting the steering mode for cable or electric steering.
1 (cable steering) ON , (electric steering) OFF
2 not used
3 not used

Now for the code H?
this indicates the throttle pot needs to be learned.

to check the lift/lower and throttle pots use this proceedure:
(do not move the dip switches, make sure S6 and S7 are in normal run mode)
verify lift/lower potentiometer
- turn truck off and unplug battery
- hook meter leads pos lead to TP3 and neg lead to TP4 on IC
- plug in battery and turn truck on and verify travel pot is set to 2.50v, if not then set it. Once set turn truck off and remove meter leads.
verify Throttle potentiometer
- hook meter pos to TP2 and neg to TP4
- turn on truck and verify 2.50v and adjust till 2.50v if not.
- once set turn off truck and remove meter leads.

NOW, that you have verified the potentiometers are set properly to center you can run learn mode on both to calibrate them.
Use this proceedure:
- keyswitch off
- move S6 (throttle) and S7 (lift/lower) to ON position
- turn keyswitch on
- an 'L' will appear on display on IC
- Return S6 to off position
- the horn will beep a single beep and a J will appear on display
- move throttle full speed to fork forks first direction, the horn will beep twice, release handle, a single beep will indicate neutral position.
- move handle in full speed to tractor first direction, horn will beep twice, release handle.
- an 'L' will appear on display
- return S7 to OFF position
- horn will give single beep and display will show 'J'
- move lift/lower control to full lift and hold till horn beeps twice
- release handle, a single beep will indicate neutral position
- move lift/lower control to full lower and hold, horn will beep twice
- release handle, horn will probably beep once to indicate neutral
if all calibrations are successful display will change to 'O' and truck is ready to run.

hopefully once you get the controls learned these other things will go away but if they do not please let us know what else is happening and we'll work on that also ;o)

good luck
