Here is what I have found so far. The meter has 5 LEDs ( 4 out of 5 lit ) around a small LCD display. When it is first powered up the LCD reads EP100 and then goes to the hour meter. None of the LEDs flash. I think that Edward T might be on to something with the traction brushes, I put the breaks in bypass and rolled the lift back and forth a few feet (started out very hard to move) took it out of bypass and the lift fired up and functioned perfectly, that is until I moved it over to the charge station to do an equalized charge on the battery. We needed to move it out of the way of a battery going out to the battery shop and when it was plugged back in it was back to no operation. The LED that I referred to as ON (in the other post)was the LED at the bottom of the handle to signal that it had been pulled down for operation.
