neutral light

Postby dnesbitt69 » Mon Sep 10, 2012 5:15 pm



on my 83 the neutral light stays on when the gear indicator doesn't register what gear you are in. the gear indicator also shows "N" no matter what gear your in.
any additional thoughts with the two issues side by side.

Has the water pump been changed?The selector switch is under that cover.It may be broken.Here's the schematic.It shows all the color codes,Each wire should go to ground as you change gears.Your switch may be stopped in the neutral mode.The only other problem could be in the wiring.Pinched and shorted???

I believe there is also a diode between the neutral wire and the switch on the clutch lever (To allow you to start the bike when not in neutral, by pulling the clutch lever in). If that diode goes short circuit I believe it could also cause the symptoms you describe.

Just guessing as I don't own an 1100 and am not familiar with the electrics on one..

I'll review the Schematic and look into that possibility.

As far as I can determine...If the neutral diode should short out,it would allow the neutral light to come on if the bike is in gear AND you pulled in the clutch lever.Otherwise there is no ground path for the neutral circuit.
The easiest is to unplug the display input and determine if the fault lies from it to the switch or to the display.
When unplugged,you should measure a short to ground on each wire one at a time as you shift gears.
If this works,you should be able to short each wire going to the display one at a time and it should show the changes.
You'll know which direction to start looking as soon as you unplug it.The neutral lamp and indicator should go off.
