Brain Trust Help needed on Parking Brake Light, Parking Brake Light Always on...... Options

[Gatornapper]

Once again need the help of the great 914 Brain Trust here........

My Parking Brake Light stays on all the time.

The switch is fairly new and it is functioning properly.

Disconnecting the brown (ground) wire to the switch, it has no continuity or resistance to ground. So it is not "grounded out" somewhere.

I see in my great 914 electrical schematic of the ground circuit for the switch and light that there are two diodes in the circuit.

I am guessing that one of them failed.

Can anyone tell me where these two diodes are located?

Or where else the problem might be?

As always,

TIA,

GN

.. They all have some type of a square plastic “tower” where the spade(s) are … is that somehow the reset “button”? I lightly tried prying the plastic block off on one and that didn’t seem to be the case (IMG:style_emoticons/default/confused24.gif)

In the pic below, the separate warning switch does actually have a button (under a little cover that's meant to be temporarily removed). I switched it out..

-I tried to be clear here ^^ that I knew the separate new single pole (that I removed) does indeed have a reset under that tiny black cover - it's obvious on that one.

Also, you're last post answered the first part of my question/statement above (plastic tower) ^^ , thanks as always.

-OK, that's good to know, thanks. Were there EARLY two-pole switches with manual buttons? Anyone got a picture of one? So probably lots of 914s with two wires to the MC would not have a button to push, by default. Which jives with my statement to the original poster, not to be surprised if there is NO button to push.

-Well Duh! ( (IMG:style_emoticons/default/biggrin.gif) ), I mean this is THE REASON I switched "back" to a two pole switch (because it matched the original wiring).

Push the button!"

-But see what I mean? - I'm hearing it again while there is actually NO button to push! (see three random examples above). I assume you mean manually of course. Since my original wiring included two wires (+/-) I would have had a two pole switch... which probably didn't have a manual button to push, if I'm understanding correctly.

-Of course I understand..me too, certainly not intended.. this is all very informative.
