Iâm putting together a commando cafe racer and now need to sort out the electrics.
I have a complete blank canvas but already possess a boyer micro digital ignition system and power box which Iâd like to use.
I've produced a wiring diagram which I think will be sufficient for my needs but would very much welcome any comments anybody may have.
Advice on cable sizes would be appriciated
Please see attachment.
Thanks in advance.
Mike

My local MoT man allowed my bike to pass with just one of the two brake switches functioning. I was a bit surprised at this and querried his decision. However he is very experienced and said that as long as either one worked that was fine for him.
The wiring diagram looks correct but having never used a Power Box I need to ask if it actually does have a separate source for the lights? My A1 Box just has two wires out going straight to the battery.

Checking the mot requiremnets the section regarding stop lamps states that:
Machines first used before 1 April 1986 must have a stop lamp that operates from at least one brake control.Machines first used on or after 1 April 1986 must have a stop lamp that operates from both brake controls.
On checking the power box wiring I have moved the ignition switch so that it isolates the power box from the ignition system and cuts the power from the battery to the lights etc.

Hi Mike, the diagram looks fine to me. One issue may be the need for the brake light to be operated from both the front and rear brake levers. This is always a contentious issue and seems to be machine-age related and the rules seem difficult to decipher. Some MoT testers can be a bit strict on this. I found this when I changed some wiring on my 1971 BSA Rocket 3.
