docc Posted May 27, 2017 Share Posted May 27, 2017 The "Running Light" circuit on the V11 is a curious animal. In my view, if the relays fail (say it ain't so! ), the Running Lights still get their fire through the Ignition Switch and Fuse#6. No relay. So, even if the headlight (and brake light, warning lights, charging, and tach) go out from relay failure (Relays #1 NC or #2 NO), you still have a tail light, tag light, instrument illumination, and a 4 watt "city" light in the headlamp bucket. A "limp home" mode, if you will. Even better, it seems the Running Lights stay on if Fuse#6 is pulled (or blown). Unless either Relay#2 or Relay#1 is also pulled (or fail), then they go out. It's an excellent redundant system to ensure the Running Lights stay lit. :thumbsup: But, I can't find how the Running Lights are *also* fed from the Relay circuit unless it is inside the left handlebar switch set. Is it? Or how? Or is my Funky-Old-Sport shorted out? curious minds and idle hands . . . Link to comment Share on other sites More sharing options...
docc Posted May 27, 2017 Author Share Posted May 27, 2017 Are the circuits crossed here, in the left hand switch between the dimmer and the Running Lights? Link to comment Share on other sites More sharing options...
docc Posted May 28, 2017 Author Share Posted May 28, 2017 Well, I can't find the Running Light (park) wires in the left handlebar switchset (took it apart and gave it a clean/lube), or any kind of *junction block* inside the switchset (or whatever that thing is in the diagram). Not sure where the Running Lights get their redundant feed from the Relays, but it's good to know it is there. Perhaps the representation on the Manual's wiring screamatic is for the "Euro" switchset that allows the headlamps to be shut off? Link to comment Share on other sites More sharing options...
Kiwi_Roy Posted May 30, 2017 Share Posted May 30, 2017 Unplug the switch that would eliminate it as the redundant source. It must come through the ignition and I don't see it going through the start relay Sent from my shoe phone! Link to comment Share on other sites More sharing options...

[i also need to test the voltage drop in the black reference wire to the regulator.] Link to comment Share on other sites More sharing options...
Kiwi_Roy Posted May 30, 2017 Share Posted May 30, 2017 I have seen mine as high as 1.0 Volts it's normally ~0.6 Sent from my shoe phone! Link to comment Share on other sites More sharing options...
