I have a 1973 Norton Commando 850. I'm using this wiring diagram for reference.
I'm trying to understand the general information about the electrical testing and what features are in these states.
Some general assumptions:
1) When the left/right indicators are on, the yellow "flasher warning" light turns on and off.
2) When the main beam is on, the green "main beam warning" is always on.
3) When the key is in 3rd or 4th position, the red "ignition warning" is on until the motorcycle starts and running then it turns off.
For the US Market, the following handlebar switches are as following:
1) Right Handlebar
1a) Top Button: No connect (black)
1b) Bottom Button: Kill switch (red)
1c) Up Rocker Position: Left indicator
1d) Middle Rocker Position: Nothing
1e) Down Rocker Position: Right indicator
2) Left Handlebar
2a) Top Button: Head Lamp Flasher (black)
2b) Bottom Button: Horn (black)
2c) Up Rocker Position: High Beam
2d) Middle Rocker Position: Standard Beam
I understand there's 4 positions:
1) Parking (one click to the left)
2) Off Position (neutral position or "noon" position)
3) Start without Pilot Lights (one click to the right)
4) Start with Pilot Lights (two clicks to the right)
The functionality for the positions as follows (to my understanding):
1) Key can be taken out and the bike can't be started. The pilot lights (front and back), tachometer, and speedo lights on. The two position light switch does nothing. Left/Right turning indicators don't work. Horn doesn't work.
2) Key can be taken out and the bike can't be started. Nothing happens. System is completely off.
3) Key can't be taken out and the bike can be started. The pilot lights (front and back), tachometer, and speedo lights are off. The two positions light switch turns on the main beam. The head lamp flasher button works. Horn works. Left/Right turning indicators work. Kill switch works.
4) Same as Position 3 with the pilot lights (front and back), tachometer, and speedo lights are always on.
Let me know if I have anything wrong or if I'm missing something.
Thanks
