In my old diesel westy (Wallace) I am having a problem that is strange
to me, but may be common to others.

When I turned on my right TS, only the rear worked. A quick look at the
front showed rot and corrosion among the terminals that made it look
like an iron civil war artifact. I have dremeled down to steel until
another one arrives.

But the left TS is more problematical. When I put on the left TS, I get
no voltage reading at the front, correct at the rear (but no light,
some terminal cleaning is in order back there) but the the dash area I
can hear a sound just like the seat belt warning buzzer and in fact may
be the seat belt warning buzzer.

Is it simply time for a new TS switch assembly?

Thanks,

Jim
