I have a Yale ERC050VGN showing code 12812 and 12820. We parked it for a week and now it has a code - maybe caused by recent high humidity? The machine will not lift or drive. The machine turns on and codes within about 5 seconds. We connected a battery showing a full charge on another machine - the display on the machine with the code is not reading the full charge. Any insights are appreciated!
