Clearance Lights & Inside Steps Problems

[Gaetan Lavoie]

I ran into a peculiar problem the other day. I rarely drive at night. However, that day I decided to leave early in the morning before the sun was up. So I was ready to go at least I thought that I was until I pull the switch for the lights and nothing light up. I scrambled to the electrical compartment that houses the relay for the lights. I wiggled the relay from the fuse/relay board and I heard a click and the clearance lights and all lights came on. However, the inside steps would no longer work. I checked the fuse and it was burned, so I replace it. Everything is working until the following day when I needed the lights again. Guess what no light. I wiggled the Clearance Light Relay and the lights came back on. But the inside steps would no longer operate - the fuse had blown. There seems to be a relation between the clearance lights and the inside steps.

I am somewhat at lost as to the cause of the problem. I have been thinking about a bad relay. Any ideas as to the nature of the problem would be welcome.

Hi Gaetan Lavoie,
Gut feel says there is a "back circuit" feeding too much voltage to the step circuit when the are turned on. For me, I leave these problems to a certified service tech. Has there been any after market devices added to the coach?

There should not be a connection between the steps or your clearance lights.
Some of the relays are the same so you can interchange them to see if the cross will be removed.
If its behind the panel may have to pull it and take a look behind it but the trouble may clear if its a wire clipping or if a wiring pin behind maybe shorting to what its mounted to.

You might check and see if you steps have lights that are conncected to the light circuit you are having trouble with.
