18. BATTERY DEAD AND WILL NOT HOLD A CHARGE.
Step 1. Check resistance of batteries.
If 13 milliohms are not measured, replace batteries (para 4-82).
If 13 milliohms are measured, go to step 2.
Step 2. Inspect battery cables for damage or looseness.
If cables are loose or damaged, tighten or replace cables (para 4-84).
If cables are not loose or damaged, fault not corrected. Notify supervisor.
19. ALTERNATOR DOES NOT CHARGE BATTERIES.

If drive belt is damaged or out of deflection limits, replace drive belt.
If drive belt is not damaged or within deflection limits, go to step 2.
Step 2. Inspect belt tensioner for looseness.
If belt tensioner is excessively loose, replace belt tensioner (para 4-62).
If belt tensioner is not excessively loose, go to step 3.
Step 3. Check alternator output voltage.
If 25 to 28 vdc is not measured, replace alternator (para 4-63).
If 25 to 28 vdc is measured, go to step 4.
Step 4. Check alternator negative cable at starter solenoid.
If a minimum 25 vdc is not present, repair or replace cable.
If a minimum 25 vdc is present, go to fault symptom #28.
