Tools Needed:
7-6. Overload Protection
A. Time Delay Relay CB7 And Fusible Link (Optional With Glow Plug)
Internal time delay relay CB7 and the fusible link protect the optional glow plug system from overheating. If glow plugs
overheat, CB7 automatically stops the heating process. Wait one minute for CB7 to automatically reset before using
glow plugs.
If the engine is hard to start in cold weather, check the fusible link and replace if open.
When a circuit breaker or fuse opens, it usually indicates a more serious problem
exists. Contact a Factory Authorized Service Agent.
