We Have a Daewoo BC30S 36V Electric Forklift Serial # CM00443, It Was Running Ok Before Lunch Come Back From Lunch, Hydraulics Work, But No Forward Or Reverse, No Attempt To Move, No Backup Beeper, Nonthing. When You First Turn The Key On It Shows A 6 (Battery ~37.8 Volts) For a Few Seconds Then Shows a "E", I Checked The Ebrake Switch, The Brake Switch & Seat Switch All Seem To Be Functioning. We Got It To Start Flashing a Code Which Was Either a 1, 2, 12 or 21 We Arent Sure Since The Display is Slightly Damaged. Any Help Would Be Great Thanks Or Documentation On Trouble shooting
