I spend a lot of time seeing everything ; Cables Fuses Conentors Everything , line contactor Etc, Etc, I really don't know wht to see or to do. It's strange. This trucks shut's down and we can't see a logical explanation, it shut'sdown in good floor or bad floor, it hapens sometimes with the machine stopped...I Think that have a problem in the alimentation circuit but Were???
Hi pedro
bruce is right change the line contactor we had alot of probs with line contactors dropping out or becoming weak causing this fault.
i would be curious if this happens when hitting a rough spot in the floor or maybe a dock plate. if so i would check to see if the line contactor is making properly and see if the tips are burnt which may be causing it to be weak and dropping out.
Check the crimps or solder connections on the contact tips for the battery connector on the machine side (the heavy cable connections where the battery plugs in on the machine). Check your B+ wires for loose connections. Do the same for the negative side.
When the whole machine shuts down like that, it's usually either a battery running down real low or a bad/loose connection in the machine itself. I don't know your machine offhand but these are the things I would check initially if I got a call for something similar. Check relays and contactors too. It could be in a controller too.
I had a Yale pallet jack (MPE060LEN/A896) a few months ago that would code out with "the tiller arm is in the down position when the key was switched on" even though the guy was just driving it. I think it was a code 32, can't remember the code offhand. Found the solder connections in the SB plug were bad. I always prefer crimping them myself.
the machine turn off like you turn of the key..
It happens with any batery , batery that still work in another machines..

Does the dash panel go blank or does the machine just stop?
Watch the battery voltage when it is driving. If it drops below a certain point under load, contactors may drop out due to low holding current and reset the machine. Also check for loose wires over bumps.
