CAT 246B Starting Issue: Power Loss and Recovery - MikePhua - 07-04-2025
The user is experiencing a situation where the CAT 246B loses all power when trying to start, but the power somehow restores itself after a period of time, and the cab receives power again.
Possible Causes and Solutions:
- Battery and Cables Check:
This issue could be related to loose battery connections or aging cables. It is recommended to check whether the battery terminals are securely tightened and to inspect the cables for any wear or corrosion. If there is any damage, replace or repair the cables as necessary.
- Starter Relay:
A faulty starter relay could cause the power loss during starting. Check if the relay is functioning properly and replace it if needed.
- Fuses and Relays:
Inspect the fuses and relays, especially those related to the starting and electrical control systems. Replace any blown fuses or faulty relays.
- Loose Connections in the Starting Circuit:
Sometimes, loose connections in the starting circuit can lead to power loss. Ensure that all connections related to the starting system are secure.
- Electrical Control Module Issue:
If none of the above steps resolve the issue, the problem may lie with the electrical control module. Further diagnosis with specialized equipment may be required.
If your CAT 246B loses power during starting but power is restored afterward, the most likely culprits are battery, wiring, or electrical components failure. By systematically checking and ruling out potential issues, you can efficiently pinpoint and resolve the problem.
