03 RK Classic Electrical Problem - Help!
I have a 2003 Road King Classic with about 40k miles. This spring when I started riding her again, the fuel gauge wasn't working. I'd ride a while then it would come on. This has been getting worse and worse. Had the bike out the other night and realized that the Fuel gauge, headlight and running lights are all not working (they will come on after riding about 20 miles or so). Touring lights, brake lights and turn signals all work fine.
I checked the fuses, no corrosion. Checked for volts at the headlight and no volts. (Did this to determine if my problem was related to a ground or power supply.)
I ordered the Electrical Diagnostic Manual for my bike today. Figured I'd also see if anyone else has had a similar problem.
This is my first post. Any assistance will be appreciated.
Thoughts?

I just got the Electrical Diagnostic Manual for my bike. I plan on spending some time on Friday working on it.
Hopefully the manual I just got has a schematic. If it does, I should be able to find the common thread easily enough.
I'll post what I learn. Maybe it can help someone else.

Unfortunately, I was too busy to get to my bike until recently. I did figure out what was wrong with it. The problem was the power relay (under the seat, behind the battery), it had burned contacts. I cleaned up the contacts and my problem is solved.
According to my wiring diagram, the passing lamps should not have worked either. But, a while back I changed out the passing lamp switch with a 3 way so I could have the high beam and passing lamps on at the same time. This provided an alternate power source for the passing lamps.
The other thing that doesn't make sense is that the fuel guage wasn't working. According to my wiring diagram, the fuel guage is fed off of a different circuit than the headlight and running lights. Not sure what changed here, but the fuel guage works fine since I cleaned up the contacts. Time to stop fixing and start riding...
