Tried to take out the old switch today, what a PIG!
Can't get decent access to loosen the *!!-* thing. Any tips, folks?

Squirt some plus gas penetrating fluid on it overnight then if it is still tight try to tighten it a fraction as this will often break the seal and will then undo.

An angled open-ended spanner, either professionally made or heated and hammered to suit. Also the ever faithfuly molegrips will grip the round part of the switch

i always work by the old adage, "if at first you don't succeed use a bigger hammer!"

Hmmm.............
The molegrips route sounds tempting............

Careful with the molegrips though as the top of the switch can be destroyed easily. Best to use a good fitting open ended spanner on the nut.

My advice for removing the stop switch - which isn't what was being asked asked....Doh!

"I used a deep socket & both extension bars - then it's dead easy. The only thing you need to watch out for is the 3 way union twisting with the stop switch and kinking the brake pipes. I braced the union with a piece of wood against the wing".

A deep socket?
Do you mean to say that you put a large socket over the round part of the switch, and twisted it off?
The actual nut behind the round piece is very akward to gain access to.

Chris, Jojax is talking about the oil pressure switch ,not the brake switch

Yikes! How did I get that wrong? Sorry for the confusion.....

For the oil pressure switch I would agree with Cam's advice....

Thanks guys.
OK, where do I connect up the vacuum gauge?
I know the copper pipe comes from the carb to the vacuum advance. Do I have to cut into this?
Cheers.

Vacuum guage needs a separate take-off from the manifold. The guage should come with a threaded adapter. Remove the manifold, drill correct sized hole (in inlet, NOT exhaust!) and tap to suit the adapter.

That explains why I have a healthy oil guage reading but constant orange light - it must be easier fitting the gauge than replacing the switch
