Hyster N45ZR-16.5:
Fuse Board Blew N45ZR c264

Original problem was a blown fuse board. Replaced it and the line contactor would once again pull in and travel and lift were OK. Then found bad aux motor. (diagnosed by: 36 volts at motor with no CAN bus problem) I'm replacing the motor Friday but I was wondering -- Is there any way the Aux motor could have smoked the fuse board? I have the book on this one but it doesn't seem to include a wiring diagram. All I see to the motor are the power cables and 2 CAN wires.

Well, I replaced the Aux motor and fuse board and all operations seem to be ok. An autopsy on the motor showed burned up mosfets. Which caused an intermittent ground on the neg side. I'm guessing the ground either caused the fuse board failure or it was just a complete coincidence that they both burned up at the same time.

Usually the regulator fails in the circuit board and cause the problem. Low battery voltage and high current draw is the most common cause. Good Luck

In the end, John's 'granny glasses' became one of his most iconic trademarks. His last pair, worn on that tragic day in 1980, are kept at 'The Beatles Story' exhibit in Liverpool, insured for over £1 million.
