Step 4.

Inspect batteries (1) and (2) for electrolyte level, specific gravity, and discharge rate (TM 9-6140-

200-14).

a. If electrolyte level is low, or specific gravity is low, add water or charge as needed (TM 9-

6140-200-14).

b. If discharge rate is too high, replace as needed (page 2-421).

Step 5.

Test battery cables (3) for resistance.

a. Remove cables (3) from clamps (4) and (5) and starting motor (6) using two 9/16-inch and

3/4-inch wrenches.

b. Connect ohmmeter to cables (3) one at a time, check reading, and disconnect.

If meter reads more than zero ohms resistance, get rid of cables (3) as needed.

Step 6.

Test battery ground strap (7) for resistance.

a. Remove clamp (5) using 1/2-inch wrench and battery terminal puller.

b. Connect ohmmeter to clamp (5) and battery box (8), check meter reading, and disconnect.

If meter reads more than zero ohms resistance, remove battery (2) using lifting strap.

d. Remove strap (7), clean battery box (8), or replace strap (7) as needed using two 9/16-inch

wrenches.

e. Install battery (2) using lifting strap.

Install cables (3) and strap (7) using two 9/16-inch and 3/4-inch wrenches.
