Reverse Lights On 2007 Tiffin Zephyr QSZ On Spartan K2 Chassis

[swmiller]

Our coach failed the latest State Inspection because the backup lights aren't working. Rear turn signal lights, brake lights, and 4 way flashers all work. In testing for current to the backup lights, we found that there is none. My problem is one of being unable to find the fuse panel for these lights. Tiffin claims the panel is under the dashboard between the steering column and the driver's side. Three people have crawled under the dash looking for the panel without any luck. The panel simply isn't there.

If any FMCA bloggers are familiar with 2007 Zephyrs, could you shed some light on the location of the panel and/or whether of not the signal to the backup lights originates from a switch on the Allison 4000 trans or the fuse panel.

Thanks.

Hi Stan, Your coach is new enough to have a sub.fuse box that some of the chassis manufactures are now installing.

The real problem is its not often mentioned in the information supplied with the owners packet.

These fuse box / relay panels are OEM specific and can be located anywhere. The most common location is in one of the rear cargo pods.

This is one style: http://www.cooperind...31000-32000.pdf

This is a different version: http://www1.cooperbu...870f1f2519d.pdf

You might give Spartan a call to ask about this type of panel. Think they would have installed it as this is a chassis wiring item. They may not have a clue as to where the coach builder attached it, but at least it might help you get an idea of what to look for and they might say its in the rear or front of the chassis wiring.

There is a tool called a circuit tracer that you could use if you could find one. It puts a tone on the circuits ( like the center connection of the backup light) then using the receiver one can fallow the tone to its relay point or the fuse location. Internet service and installers use them to fined lost circuits in among all those wires.

Not sure where the Reverse light switch circuit connection is for your model Transmission.

Hope this helps. Rich.

Turn on your flashers and follow the noise. This may help locate the fuse.

Thanks for your input. I talked to Spartan Chassis and have been able to locate the fuse. I appreciate your replies. Rich, it turns the fuse box is located in the compartment 2nd from the rear on the passenger side just as you suggested. Thank you.
