I have a hyster e65xn-40 serial a268n07933k at one of our customers. I recently displayed code 12332. could not get a straight answer from dealer on meaning and definition of code. found that pump motor is twitching when code is being displayed. From past experience went to the motor speed sensor (encoder). swapped with another truck and it fixed the problem. Roughly 13 working hours later unit shut down again. Could not find the source of the problem. Next day truck worked like it never broke down. Roughly 35 working hours later unit goes down again. Was recommended to change out pump motor. Well i did that and 25 minutes later went down again. Can anyone out there please help. We now have a book coming on the unit but who knows when that will get here.
