a. If batteries are defective, replace (page 2-838).
b. If batteries are not defective, go to step 2.
Step 2.Using multimeter, set to 20 vdc scale, connect red test lead to battery positive
(+) cable (4) and black test lead to ground. Have assistant start engine (TM 5-
3805-254-10). Check for 13 to 15.5 vdc on multimeter. Have assistant shut
down engine (TM 5-3805-254-10). Disconnect test leads.
