Periodic System Maintenance
Important
TT150 system maintenance should be done at least once a year. Preferably, each time
preventative maintenance is done, the following should also occur:
•
Inspect all mounts to ensure fasteners are in place
•
Inspect the trailer 7-way harness to ensure that the TT150 connection is solid and the
fuses are not burnt out
•
Inspect all cables for damage and/or deterioration
•
Inspect the 7-way
•
Clean the 7-way pins, especially the center Pin 7 (AUX) and the top Pin 1 (Ground)
