RAM 1500 Van V8-5.9L VIN Z (1998)
Thermal Limiting Fuse: Testing and Inspection
The thermal limiter switch is calibrated to open and close as follows:
_
Open circuit (no continuity) at 125° C ± 3° C (255° F ± 5° F)
_
Closed circuit (continuity) at 110° C ± 6° C (230° F ± 10° F).
1. Unplug the wire harness connectors from the thermal limiter switch.
2. Use an ohmmeter to check for correct continuity, as indicated above, between the two thermal limiter switch terminals. if the continuity is
incorrect, replace the faulty switch.
