Title: More C15 Woes
Post by: TIGERJ on 03 March, 2017, 12:12:24
High people
Included a picture of my stoplight switch.
Any idea where and how it works.
Number on switch is 31827B1174
The switch is normally closed ???

Tim.

This type of stop light switch is normally operated by a small bracket attached to the backend of the brake lever which pushes against the moving arm on the switch. The switch must therefore be mounted just above the brake lever pivot point as on an A65. Didn't think this type of switch was fitted to a C15 but will go away and check.

Just checked. The switch is mounted under the LH swinging arm pivot bolt and is activated by a small pin that projects inwards at the backend of the brake lever.

Does this mean I need to remove the swinging arm bolt to fit the switch ?

Yes - you need to remove the bolt that screws into the swinging arm spindle which also holds the lower member of the sub-frame in place.
