Hello I have a 1993 FD620D117993 john deere 6x4 gator. The lift bed suddenly quit working. What happened was the battery was dead, i tried to charge it up, it wouldnt take much of a charge, so i did get enough of a charge to raise up the lift bed, so it was working fine. Went and purchased a new battery, put the battery in and now the lift gate wont do anything, so is this coincidence, or did i knock something loose when i changed the battery? I dont have a schematic but sure could use some help finding one. This is all new to me for my husband used to do all this. Any help would be appreciate.
