the wing nuts from backing off the post.
The WorkHorse Sentinel battery packs are
held in place by four sets of washers, lock washers, and

of washers and wing nut can become loose and
eventually fall onto the PIO board. This has caused the
PIO board to short out.

Tighten the bolts to the recommended
torque value of 5.6 Newton-meters (50
pound-inches).
