Switches have been unavailable for 20+ years

 

Not sure how a pressure switch could be used as an option for a mechanical one in this situation

If its working ... leave it alone

Most people would have never even seen the light come on in their lives

Thanks Datto for your reply, I don't think you have read my post above, where i continuity tested my switch that is Not working.
So nope, my light would not have come on at all based on that.
I have tested the wiring circuit to earth which does turn my dash light on. So no probs there.

Switch availability... is my sole reason to come up with a workable solution. When they are all gone, or the last 1 in existance costs $1,000,000.00 then someone can make something work (surely).

Sharing Idea's and experiences to the forum is what this forum is all about. The good, the bad, the ugly.

The internals of the oil pressure switch will be mechanical having a spring inside to close the contacts (single wire earthing circuit) to turn on the light, the energy source will be fluid pressure.

So Instead of using fluid pressure, as there wont be any in this case, and Insert a detent pin into the oriface of the replacement switch (just like the original switch has) efectively has to work the same way.

Admittedly there will be trial and error as to the size of the switch oriface, and detent pin. Possibly have to drill the oriface larger in the switch to accommodate a suitable detent pin, which need not necessarily be steel.

Anyway the theory seams Plauseable to this Mythbusting concept.

Jaso.

Might work

I stay away from electrics... they confuse me

Brakes are easier

Ok, my M/C and Booster are back from BHSS.

They advised the M/C was not compensating correctly, the secondary piston spring didn't have enough pressure to return the piston, its now been replaced.
So I am wondering "IF" when attempting to Vaccuum bleed it, the vaccuum may have drawn the piston forward, causing the cup to cover the compensating port?
And pedal bleeding, the piston just not returning enough.
Either way, its been re-zinced, honed, rekitted and tested, ready to refit. $237.45-inc gst.

They also had to rekit my booster as it failed its testing. $385.73-inc gst.

They have also adjusted the booster pushrod to suit the M/C too (30mm). So I should not have to touch that either...

Weekend will see this bolted back on and bled up.
