Battery being drained

Komatsu FG15ST-17

I'm having trouble with the forklift maintaining a charge. put a meter to it and can see the voltage drop slowly. I've searched online for a wiring diagram and I cant find one. Does anyone know where I can get one? or if someone can help me troubleshoot the problem, I would greatly appreciate it, thank you.

The Unit is off and we have a meter on the battery, shows that its slowly draining. when we removed the main power from the starter, the voltage shoots back up again. we started unplugging one connector at a time to see if one of them has a short, but no luck yet.

The voltage is dropping while the unit is running or off ?
