Passing Lamp fuse issues
03 Road King Classic.
I continue to blow the Passing Lamps/Aux fuse. I installed a 15 amp (10 amp is recommended OEM), my local indepentent even moved up to a 20 amp and it is still blowing.
What have I done....
1.) modified passing lamp to remain "ON" when High Beams are selected, no problems for over 6K miles
2.) installed new dual element Halogen headlight and Halogen passing lamps, have been blowing fuses ever since.
Help!!!

Not sure what your problem is but you need to understand some basic wiring. The sole purpose of a fuse is to protect the wiring, not the component. If you're runnung a 20 amp fuse in a 10 amp circuit, you're asking for an electrical fire. It's just a matter of time. If you're popping fuses, for what ever reason, more current is trying to get through the wire than the wire can handle.

you're running too much thru the fuse and the switch.
Pickup an aux lighting harness from Kuryakyn (#2328 - $29.99)
you wire the hot leg of the relay to the positive terminal of the battery
the halogen passing lamps go on the leg of the relay
you then wire the relay into the Aux switch.
the only current going thru the Aux fuse will be the minute amount it will take to engage the relay when you turn the Aux switch on.
the main feed for the lights will flow thru the relay (which has it's own fuse) from the battery directly to the passing lights.
I added a pair of 50 watt Kuryakyn silver bullets to my Ultra... along with the relay harness.. have not had a bit of problems

"installed new dual element Halogen headlight and Halogen passing lamps, have been blowing fuses ever since."
Yes too much draw unless you have an intermittant short in the wiring also. I have halogens on my '97 FLSTC and I can tell the draw when I'm at idle cuz charger barely keeps up and the lights dim. Could try resetting the switch (and the 15a fuse) to shut off in the high mode since the high beam circuit has the most current draw.
