(1) Unscrew and remove all battery filler caps (2) and check electrolyte
level. If electrolyte level is below the ledge in the battery filler opening, add

improperly adjusted charging system. Notify unit maintenance if the problem
continues.

replace caps (2) if damaged.

battery cables (3), battery holddowns (8), and shunt (4) for corrosion, damage, or
