Misadjusted or defective kill switch.
Brakes not being released.
Check switch to insure proper closure.
Open circuit between battery positive TB3.
Check for loose connections or broken wire between
switch and TB3, between key switch and positive
side of the kill switch and between kill switch and

Check for loose connections or broken wire from
TB4 and to TB3.

footswitch (deadman) and related wiring ok?
If unit has safety arms on either side of platform and IF it does and has enable switches in the arms, are they working ok?

got this fixed, but forks wont go up or down unless i engage solinoid by hand

Code -15 is battery volts low,check your battery state of charge and the charger to make sure they are good,sounds like a low/weak battery.
Code 8 for controller box is as follows:

If lower is not requested and the voltage at the
Load Holding Solenoid is less than 1 volt for at
least 1/2 second.
Or
If lower is requested and the Load Holding
Solenoid voltage is greater than 1 volt for 1/2
second.

Corrective Action:

Corrective Actions and Checks:
1. Check the wiring between the Load Holding Solenoid and the
Interface Card (JPS5-2/JPS5-1). Check for both continuity and
positive connections.
With the key switch On, there should always be B+ on pin 2 of
the Load Holding Solenoid.
2. Connect a volt meter between JPS5-1 and TP4 on the contactor
panel. Turn the key switch On. If the voltage is less than 1 volt
without a code on the Interface Card, replace the Interface Card.
3. Check the Load Holding Solenoid for proper resistance.
Remember to run Learn if the firmware or Interface Card is
replaced
