Thread: series 3 hand brake light switch

didnt know that the series III had a handbrake switch...........

choke warning, alt warning, hi beam indicator and low oil pressure light was all I remember them having.

YEP.
And mine also has a pair of what look like extention speaker plug holes, coloured white and light blue, in the dash binacle as well, and I'm buggered if I can work out what they are for.

wow how advanced tell me more about your series 3

Just looked at the Series 3 parts book - no mention of a hand brake switch. There is a brake failure warning system on dual braking installations, which may have switches on the Pedal assembly (pedal movement), booster (vacuum failure) and on the distribution block, which has a switch to detect differential pressure between front and rear. I think the last was the only one fitted in this country, and, of course, early Series 3 had a single circuit braking system with no warning lights at all.

They should be for suppling a power source

I have a centre dash cluster that has a brake failure light and a hand brake light it was removed from a 1981 series 3

It's on the handbrake mounting system under the seatbox. The light itself is in the triangular section in the dash center.

I think there is a fluid level switch on the master cylinder of the dual circuit S3's, that lights a warning lamp on the dash. There is another rectangular lamp with the Parking Brake light, in the center dash. That might be it, John.

Okay. The other end doesn't go anywhere anyway.
A white and blue wiring set, that doesn't connect to any thing at either end. Bewdy.
It's all being changed anyway, so I've got a spare power run now.

the hand brake light in those is mounted under the arm on a bracket on the seat box and is only there to let you know that the handbrake is not fully down. its an after market setup so almost any normaly closed push to open switch will be up to the task.
