handbrake indicator not working
jumped in the car today and noticed that the indicator light for the use of the handbrake did not appear to be working. As the same indicator is used
as brake fliud warning lamp, whipped of the top of the brake fluid and the light came on , so it is not the bulb.
then I took the top of the transmission tunnel to get access to the handbrake, and I can see a single spade connector attached to a micro swtich on
the handbrake, which is depressed when the handbrake is not on, and is released when you pull on the handbrake.
This single spade connector is then wired into the main loom in the tranny tunnel.
my thinking so far is now, either the micro switch itself is fubard, or the wire is fubarred somewhere in the loom..
As I know more about quantum mechanics that I do automotive electrics (and I know very little about quantum mechanics) and I have no idea as to how
the switch/wiring works, any good tips for finding the fault here?
cheers

connect the spade connector to an earth on the car if it lights up its a faulty switch if not its a wiring loom fault

thanks Ian, I have just run out to the car. put a earth on the spade connetor and the bulb lights up, so looks like it is a swtich fault. can they
simply be replaced, looks like it is part of the handbrake mechanism?
cheers

You should be able to buy a new microswitch and replace it, even it it needs a new bracket making up to mount it. Try to take the old one out,and
either post a picture on here, or search on ebay for a replacement.... There are a few different types, so you need to buy one that works in the same
way.

I nipped out this morning, on the way to work, and it looks like the switch is revited into position. Will try and take some photo's tonight to
see what the collective think.

The switch is only to test if the low fluid light is working. If you can't change the switch, just put a momentary push button on the dash for
MOT time.

thanks for all the posts gents.
I took out the handbrake last night and removed the switch, gave all the contacts a good clean and assembled it all back together. It looks initially
like the switch still works, but there is a bad earth between handbrake and chassis.
So some more investigation, breakdown, cleaning and re-assembly ahead, to see if it I can get it working again without having to purchase a new
switch.
will let you know how I get on.
cheers

on investigation last night, the switch continued to have a bad earth, so broke the switch down into is components, taking out all the metal bits,
springs, connectors, etc gave all the metals a clean and sprayed with protective fluid, assembled the switch and put it all back together again, -
bingo the handbrake switch works -  in the true cost of locost - saved myself £20 in buying a new micro switch
Cheers
