We (the other techs and myself) had gone over Static as a possible cause of the encoder failure. This truck does us Non-Marking tires, and pulls pallets off an automated shrink-wrapper....So you can imagine the possible static buildup. So we've since then made sure the static strap is clean, on top of adding a chain dragging behind, and also running grounding wires between the battery compartment, seat, hood, power unit, and main frame of truck. We even went through and did Ohm testing, and had good continuity to the grounding chain.

Currently, the truck is down, and they're using a loaner of the exact same model, with no issues and no static problems. So I think that kind of eliminates the environment as a possible cause of failure.

But at this point, I'm open to any ideas. Lol
