HELP-Headlight Wire to Cut During Starting '96 FLH
I'm looking to disconnect the mystery wire that keeps the headlight powered while engaging the starter switch. I have the headlight assembly out. Can anyone give me direction where this jumper wire is that can be disconnected? There's 3 wires to the headlight connector, yellow, black and white. From there in goes into a larger loom. Hoping I can find this without pulling the fairing completely off. TIA.

There is no wire that keeps the headlight on while starting and nothing else. Just the power wire from the switch. You would need to disconnect the low beam wire and put a relay in the circuit, or you could probably disconnect the ground wire (black) and put a relay in the circuit there. The relay should use the normally closed contacts and be energized by either the oil pressure light or starter relay or solenoid when powered for starting.
Depending on your bike, there may be a wire at the ignition switch that jumpers the Ignition On and Lights positions of the switch, if you have that kind of switch.

In 1980 federal law mandated that motorcycles had to have a headlight that is always on...Harley's answer was to put a "jumper wire" on the ignition switch so they didn't have to change the wiring...this is the only jumper wire I have ever heard being associated with the headlight...and I don't believe a 96 would even have that.

---The Evo era bikes have a jumper wire that connects the light circuit to both "Ign" and "Lights" positions on the key switch, to be in compliance with federal regs that say all bikes have to have the headlight on when the engine is running. This was a poorly thought out, but very simple and cost effective way to bring the bikes into compliance.
On modern bikes, I noticed that the lights all go out when the starter is engaged, which means to me that they finally worked in the circuitry.
On my 90 Tour Glide, I just cut the jumper wire and remind myself to turn the switch to lights after the engine is running. Works like a charm for me.----
Yes the referenced jumper wire on the key switch. How best can I access this? Is it just a simple loop jumper??

you can find a wiring diagram (.pdf) at the crane cams website.
hit the starter, & relay kills the light.
this gives full power to the starter and ignition.
My fxrp has the old style, off-ign-ign & lights

unfortunately i do not know where the jumper is, but it was removed on my bike. Just make sure you remember to turn the lights on after starting up during the day, otherwise one of the ladies and gentlemen of your local law enforcement agency will kindly remind you.

Its going to be the only wire that jumps from one circuit breaker to the one next to it.I've done this to mine. You didn't mention your model and I'm not familar with wiring on other than my flhtp, on mine the batwing had to come off and all the circuit breaker are positioned under the stereo, it was the orange wire I think my manual is in the shop and its -20C but if you really need to know I can take a look see. Best thing is give your year and model or better yet look it up in your manual.
