Strange Harley Road King Plugs
« on: July 20, 2025, 12:36:20 PM »
I've finally gotten around to working on a 2002 HD Road King a friend of mine gave me; it hasn't run in about six years and I've been trying to get it running but so far no luck, although I think I've found a clue in a blown fuse, but that's not why I'm writing. Does anybody have one of these bikes and can tell me what these plugs are for? I removed the rubber plug on the one on the right so you can get a better view of it, but what do they go to? They live in the battery compartment, but I can't find a similar matching plug on the bike, and they don't fit together; the bike also won't go into Neutral/I can't get the Neutral light indicator to illuminate either. There's also a fresh battery in the fob, too (Man, those things are a PITA!!) Any ideas??

they're to recharge your 'BRO' levels, especially needed if you find yourself looking covetously at a honda

and you really don't want to know where they plug into

I have a 2001 Softail service manual but no longer the bike. Might have similarities? Also a 2002 accessory and parts book and a bunch of take offs from my 2003 Fat Boy, most new or almost. Can you zoom out a little on your pictures? Carburetor or fuel injection? I'd almost bet one of those is for the computer hook up OBD port. And maybe a security system, etc?
As of today 3/13/2012 my original owner 75 CB750F has made it through 3 wives, er EX-wives. Free at last.  ;-)

Okay, so they're nothing 'important' they plug into...full disclosure I'm trying to get this bike started, it's been sitting since '19, and I think I have it narrowed down to the fuel check valve - all the fuses are good, but I have Zero fuel pressure (as indicated by the 'official' and pretty dang pricy 'Fuel Tool'). It's fuel injected and I have replaced everything in the tank - new pump, pressure valve, injectors etc - but I still can't get fuel to flow. It'll run on starting fluid, and with the Reinhart pipes on it I can tell my neighbors are gonna hate me - but I live in the country, sooo...

Beyond all that I know nothing about this bike or how it operates - I'm more of a carburetor guy - although the bike seems to be more like a CAR than a bike! And I accidentally discovered it has an alarm system on it - yah, THAT was fun...fwiw, I do have the operators manual and the other two really expensive electrical and repair manuals, purchased in happier times...
