hi guys. on a 2010 roadking behind the forks under the headlight, there is a plug. The housing to this plus appears to be broken so when you plug the male part in, it doesn't make a good connection and when you touch it, all the lights go off. It's like it triggers a relay. There appears to be a loop wire at the end, a jumper for some reason. I dunno what that's for.

Also the extra driving lights, I can't get them to come on at all. Are they on a separate circuit?

There is a toggle switch on the back of the headlight, doesn't seem to do anything but I suspect this is there because it was a cop bike.

Anyone have this problem? How do you fix it?



this is up behind the headlight

 

Toggle switch is for accessories if you use them. It would run anything you wire to the accessory plug/circuit. To fix that plug, get a new plug receptacle from dealer

 

Dawg;

do you think it's because of this plug that the lights kick on and off?
- is this a matter of cutting that plug out and soldering on a new plug? or do I need a whole new wiring harness.
-- ok I found that they wired the driving lights into one of the "red cop switches" thats why they would not go on.

 

At the risk of feeling like I write this in way too many posts here goes.

Buy yourself a factory service manual. It will be invaluable.

As for the plug, no soldering required. All HD plugs disassemble, instructions in the FSM. Any tools for r & r of the plug can be found easily enough on Amazon or eBay for not much.

 

ORradtech, I think I recall now that you mention that. These are the plugs that you push the pin above the wire to release them right?

 

Yes, kind of. There are several different styles of plugs on your bike. Each style is a bit different. Again, the fsm will tell all.
