Introduction.
While
there is considerable printed information covering the early model
Braves the main omission for later model S2s fitted with the Lucas RM 13
alternator is the lack of a wiring diagram. In a recent telephone
conversation with another Brave owner he informed me that all major
electrical components were the same as those used on Royal Enfields of
similar vintage.
Objective.
To
produce an accurate wiring diagram for the late model S2 and a diagram
for harness manufacture.
Execution.
With
care I detached a very dirty and tatty wiring harness from my bike and
found that with the exception of the actual harness tape all the wires
were in remarkably good condition with all terminals in position and
appeared to be original. This was then checked against the R.E. wiring
diagram. All equipment was cleaned , reassembled and checked for correct
operation.

Light/Medium/Dark Green, the Medium Green joins to Green/Yellow on the
