I had the same issue. Having a 0 on the gauge prevents the forks from lifting but driving is ok. No codes. The battery is fully charged. for some reason, the circuit board stops reading the battery voltage. I replaced the circuit board in the arm and this fixed the problem. The part number is: TO 00590-47051-71
