Hi all.

This for an '81 Westy.

Bentley shows a transistor symbol ("solid state circuitry") in the
brake warning light assembly. It appears to work with the brake light
switches on the master cylinder to warn of a failure of a brake
hydrualic circuit.

This transistor has 2 grounds. A ground goes to one side from the oil
pressure light (when pressure switch closed), the other side has a
constant ground from the body.

Why is there a ground from the oil pressure switch wire?

I appreciate any insights. It will help me trouble shoot my Jetta
engine install.

Thanks,

Neil.
