Unit was running great, battery was low so we charged it, charger (enersys impaq) gives green light and the forklift diag. screen says the battery is at 37.2V (it's a 36V lift) but the forklift LCD says it's low with 2 bars remaining. Unit runs in all directions with bright lights, the forks move in all direction except it won't lift, so we enter diagnostic mode and it shows this one error " Logic Failure #1, 12705h #1, 33* degrees. Did some research and it seems everything is pointing to the Nissan Controller and PCM Module Assembly (#Hel-23710-4K40A) not sure if that's the part number of ours, no other real problem because we've never had an issue before except we did have to bring all the battery cells back to normal level with about 16 to 22 oz of distill water because our AZ heat wreaks havoc on the batteries during summer, this summer we were shutdown for a month. Stand-up model unit - Any help or advice is most appreciated in advance - Thank you, Phil
