CONDITION/INDICATION
Are water distributor batteries at 70% or more of full charge?
DECISION
No - Service (WP 0082), or replace batteries. (WP 0086) Verify problem is solved. (Step 9 - Is engine crank time
normal during engine starts?)
Yes - Go to step 4. (Step 4 - Does air filter restriction indicator indicate restriction?)
STEP 4
Does air filter restriction indicator indicate restriction?
NOTE
Sight glass on air restriction gauge will be red in color if restriction is present.
Visually inspect air filter restriction indicator.
