Running lights fuse

[george starkweather]

Is there a fuse for the running lights? I had to replace the running lights on our '05 Monterey. The light comes on in the dash to indicate that the lights are on, but they do not light up. Could there be another problem? If there is a fuse, where is it?

George,
If your coach has the multiplex system, fuses F66 & F70 are for the parking/running lights. If it is a non-multiplex system, CB7 is the thermal circuit brealer for the running lights. It feeds relay R1. All are in the front electrical bay below the driver. Check the layout diagram to be sure of the relay and CB#s as I don't have an 05 diagram.

By “running lights” I assume you mean the parking lights.

On my 06 Monterey, only a year newer and in most regards little different from yours, the top left relay in the bay, K1, is parking lights as Steve remarked, as is circuit breaker CB7.  Of the 2 vertical buss’ directly above the solenoid, CB7 is the 7th breaker down on the left one.  Thermal breakers usually reset and rarely fail, but connections can loosen or corrode causing resistance.

Also check the vertical common terminal buss, TB1, for the connection integrity of the top wire(s) and nut.  That should be the one for the parking lights;  of the two far right buss’ in the bay, TB1 is the left one.

Thank you for the information. Mysteriously the lights started working. Maybe the breaker reset itself.

George,
Suggest you remove and reinsert the relay and insure that the nut on TB1-1 is tight. Either can cause an intermittent connection.

A bad connection or loose connection of the pigtail either at coach or car can cause a short in the system. It can cause the self reset fuse to get hot enough to no longer reset. If your lights mysteriously come back on wiggle the pigtail connections at your toad or at the coach and see if it effects the lights.
