If the problem is not resolved, proceed to Test Step 4.
4. Check for Slow Cranking Speed
A. Connect Cat ET.
B. Use Cat ET to monitor the following while cranking the engine:
- Engine speed
Note: If the engine cranks too slowly, the engine will not start.
C. Check for the following problems:
- Low voltage for an electric starting system
- Low air pressure for an air start system
- Excess parasitic load
- Engagement all starters on a multiple starting motor system
- Hydraulic starters and the supply pump
- Starting signal being sent from controller
Cranking Speed
Result: The engine speed is greater than 100 rpm for a duration of four revolutions.
Proceed to Test Step 5.
Result: The engine speed is not greater than 100 rpm for a duration of four revolutions.
Repair: Repair or replace the damaged components.
If the problem is not resolved, proceed to Test Step 5.
5. Check the Starting Aids (if Equipped)
