brake lights not working on 81 gld

**lawny** · 19-10-2009, 04:34 PM

the scenario: brake lights are not working, globes are fine, fuse is fine so my guess is it is the brake light switch. there is no switch behind the pedal, i have been told this is located on the master cylinder???? not sure which plug it is or even if i am looking at the right thing. there is a plug on top, the side and something that is not even connected to anything. i have attached photos so u can see what i am looking at. please help!

photo shows one on side and one on top

photo shows one going nowhere

hey mate,

its definately the switch, and a common problem at that. i would suggest getting hold of a manula with wiring diagrams and use the colour codes to figure which switch is which. however, replace both, as its not much money to do so.

i have seen setups with 3 connectors and setups with 2 connectos, and i am only familiar with the 2 connector setup - however you will be able to find out what you need simply by using a jumper wire to short both connectors one at a time and see which one turns the brake lights on

HTH!

PS - ring HSY autoparts for those sensors, thats where i got them last time. in sydney, 8339 8339

if you mean that connector doing nothing under the washer bottle, its there on just about every mk1.... i think some car's had some other connector on the gb for something or other, but most didnt.

nothing to worry about.

Would you have been happier if he had pointed out that there is a specific Mk 1 section ?

Hi Lawny,
just replaced these switches on my '77.
Brake lights had stopped working.

I got them from Unique Imported Parts in Dandedong-$16 ea.
