Course: Diesel Equipment Technology I (20107-I) > Section: Preventive Maintenance and Inspection: Servicing the Drive Train

Checking should include a visual inspection to look for

- proper routing
- proper connections
- secure harnesses
- chafed harnesses
- sensors and switches
- electrical components (e.g., motors, solenoids, and switches).

- When inspecting the area around a transmission, what should be done when a wiring connector wire is tied?
- When inspecting the wire harness routing, what should be done when a harness is not secured properly?
- How should an electrical wire damaged during a transmission installation be repaired?
- What should be done when a hole is drilled through a firewall to connect a power wire that was damaged during a recent installation and no grommet was used to protect the wire rubbing against the metal?
