A few weeks ago I had the opportunity to purchase a Yale 30 reach truck.

It had a dead battery so as a temporary workaround to move it we wired 3 12v deep cycle batteries in series (I know not a great idea) so we could get it on our trailer and back to our facility. Worked fine, the mast even raised when we tried. Got that job done.

Well a few days later after it was at our facility parked waiting for a new battery I decided I wanted to move it further out of the way, recharged the 3 batteries in it before moving it and it moved about 20' and decided it was done. Everything shut off. I didn't see it but a bystander says they saw sparks come from the battery compartment when it happened, not sure if the batteries moved and arced or what. Unplugged it and tried again, main hydraulic pump for steering, reach, side shift and tilt comes on but the display screen doesn't light up or go through its usual startup sequence.

Took the panel covering the electronics off and found a blown 1A AGC fuse, replaced it, charged the batteries up and the same thing, only the main hydraulic pump comes on. No lights on the screen and the 1A fuse blows immediately when I step on the dead man pedal and the main pump comes on.

That was about a week ago, fast forward to today we just got in a new battery for it and were hoping that would resolve the issue, but unfortunately its still continually blowing that 1A fuse and the display is not turning on.

It does move though a little bit. If I hold the joystick for 2-3 seconds it starts to creep forward/backwards. The mast will not raise at all.


Anyone have any ideas or have seen similar before? I'm hoping its not the display that's blown because its pretty spendy. There's no burnt or loose connections and the fluid power module is not displaying any error codes.

I don't have the model number right now but will check in the morning.
