http://www.vn750.com/forum/19-electrical/87625-guide-bypassing-reserve-lighting-unit-2.htmlAhhhhh, so maybe I didn't need to do the mod in the first place. This LED light was "supposed" to be plug and play. Comes with an inline driver that is supposed to stop error messages due to lower wattage.
Does anyone know if the OPT7 LED bulb needs either of these mods?
Pretty sure its the LAW to run a headlight on your Motorcycle here in sunny Florida.So......my Stator pooped out so tried the "Battery tender" thing,was OK but really tough to figure when that battery would die...then leave you sitting/walking.Not a enjoyable way to ride!! :frown2:Hey that is a good idea if a stator goes out, pull the headlight fuse and just ride in the daytime. You can do the switch mod later if you decide to replace the stator. I would guess pulling the fuse would cut the power to everything related to the head light circuit. Will have to look at a good wiring diagram, the ones I've found so far for the vulcan are terrible, small, black and white, plus blurred out.
Can you explain this with wire colors and step by step instructions I did the blue wire mod and would like to install a switch?For the Blue wire mod cons - Headlight stays on when key is turned on, which obviously takes power away from starting.
What I did was splice in a good quality mini toggle switch between the ground headlight wire inside the headlight cover, drilled a small hole in the lower head light cover to run the mini toggle switch through. The switch can then be off for starting, then easily turned on when warmed up and ready to ride. Very inexpensive easy fix to get full power for starting, after doing the Mod.
The reserve lighting unit will automatically switch from low beam to high beam if it detects a filament failure. Without you having to toggle the headlight switch. If there is any intention on going to an LED headlight, it could cause flickering because the LED bulbs do not consume as much power as the stock incandescent bulbs. It can be bypassed very simply by using a jumper across 2 pins on the connector. That mod can be easily found on here (with pics) by running a search on “RLU bypass”What is the “reserve” lighting unit for?
And how do I check it’s working please?
As still baffled as to why I have power going to the blue wire from the headlight fuse, but no power at the light... 🤔
