Was running unit on blocks and ran down to last bar of BDI and battery light flashes and will not travel F or R. Still had hydraulics. Pushed unit over to charger. After 2 hours still no travel and no codes. Traction fuse is good. Getting voltage to the accel POT and out. Switch works as well when accellerator is pressed. The small toggle switch by the 2 fuses under the floor is in the centered position. Not sure what to look at next.
