In most cases, the 10 amp fuse installed by the factory is sufficient. However, some coaches equipped with a ShurFlo water pump (Newmar part # 127488) blow the 10 amp water pump fuse.

modules to fail to automatically acquire their network ID when installed. When operating a compartment door push button, this scenario could potentially cause two different doors to open instead of just one. The ID issue should have only occurred when the module was installed for the first time during production. Coaches configured correctly during production (and operational when shipped) will continue to operate correctly and do not need updated. Coaches built after production unit #530451 have had the software update completed and should not have any ID configuration issues during the installation process.

coach in the event of a sensor or door switch failure. In the event of a step failure, the person(s) inside the coach would have a large gap between the door threshold and the ground. The person(s) may have to exit via the large gap or the emergency exit door to get out of the coach.

If affected, the USB ports may not be active as the USB input to the Xite Infotainment center. The affected USB input is normally located on the driver side console

After testing, Riverpark believes that some of the Kingston SD cards were defective from the factory. In response to their findings, Newmar Corporation is issuing TSB 487 to inform dealers and service personnel of the defective parts. Issue: When the SD card plays in the Xite Infotainment Center, it loses communication after a period of time (typically 7-10 minutes). The system becomes sluggish and tries to re-boot continuously. This is partly due to the inability to read the cards information quickly enough, causing the radio?s CPU to ?max out,? resulting in the previously described freezing and rebooting symptoms.

G3 system.

This will only apply to coaches equipped with an HDMI/ CAT6 splitter AND the customer has installed a Geni-type satellite receiver. In this scenario, the customer may have issues trying to select satellite stations that toggle between high definition (HD) and standard definition.

Torque the mounting bolts (if needed) to 30 ft. pounds. A ground cable may also be installed to improve the overall grounding of the HWH pump assembly.

The switch has been added to the front overhead cabinet during production on later 2018 models. If the HWH system fails to operate the pump assembly when using the leveling system touchpad, slideout switches, or the entrance step, this reset switch will provide the coach owner with a more convenient location for resetting the HWH system. This will eliminate the need to pull the F-11 fuse or exit the coach to turn off the chassis disconnect in the event of a system lockout. Issue: In the event of a step failure, the person(s) inside the coach would have a large gap between the door threshold and the ground. The person(s) may have to exit via the large gap or the emergency exit door to get out of the coach.
