Electrical problem with RF light and RR lic plate light...

[Sean]

So my CAV (#27) is having this problem with the lights. I don't have the RF lower white marker light and the RR license plate light. Did the obvious. Checked the bulbs etc. They have good grounds. Checked the plugs on the front body and no power to the harness for the lights... at the plug (body side). Checked the fuses. They are all good. Any ideas? What is that symbol with the 1A next to it? I pointed to it with my pen. The red and white wire is not powered up...that is the root of the problem. :huh:

Not the way we draw them in the US but I'm pretty sure 1A, 2A, etc are all fuses. If fuse 1A were blown you would have your symptoms. Or if it is OK but not making good contact with it's socket. If this is correct then your right rear light should be out as well. If the RR light is working, then you have a very different problem that will take more investigation to diagnose.

In normal circuit diagrams the symbol you are referring to is a fuse.
The 1a or 2a denotes current rating eg; 1 amp, 2amp etc.
The easiest way to check is with a multimeter or a test lamp.
Is the left side ok?, as both sides feed from the same source according to your diagram.
If so ground one side of the test lamp or meter and check for power at both sides of the fuse.
If you get power at the supply side of the fuse and not at the other side of the fuse then that is your problem.

I wonder if that is a fuseable link vs an in line conventional fuse. If so it may not be as obvious to see.

It turns out the 1A 2A are the locations in the fuse block. My problem was caused by a wire working it's way out of the back of the fuse block. Got her all fixed and back on the road.
