Hey Deme. So, this circuit is fairly straight forward. Fuse F1, in the front fuse box feeds a number of things, In this case, power comes from F1, through a dedicated line, directly to the ignition switch. No relays are involved. When the ignition switch is turned to ON, a set of contacts closes and energizes the circuit feeding those four groups of lights. Those contacts are also dedicated to this circuit and don't feed anything else. Again, no relays involved at this point, either. Those four groups of lights are:
- the plate light
- the tail lights
- the fender tip lights
- and the Day Lights. Those are those little round LED lights that are in the upper corners of your headlight housing
If all four of those lights are out, then the common denominator is either Fuse F1, the ignition switch contacts, or a very smart rodent that chewed on just the right wire.
I know you said that you checked the fuses, but just to be conservative, replace Fuse F1 in the front fuse box with a brand new fuse. If there is still no joy, then it's either the wiring or the switch. I would start with a wiring inspection in the vicinity of the ignition switch area, since that is where the common wire would be.
If it comes to the point that you have to replace the ignition switch, that can be a real pita. You have the old version of DESS. Officially, a switch replacement also requires a DESS module replacement with the old version of DESS. Not required with the new version of DESS. However, there is a work-around that will avoid that. But, that's another 5 paragraphs so we'll cross that bridge when we come to it.
First, replace the fuse and see what happens.
Now might be a good time for you to invest in a repair manual for that machine. You can download one here:
