Accidental ground in fuel guage and park brake light

[pantah]

First my parking brake light wouldn't go off when the brake was released. Then the fuel gauge read half way up when engine was first started. Now it is always pegged. I have the wiring diagram but it doesn't tell me physically where I should look first on the wiring harness. It looks like I have a ground fault somewhere. Any ideas.

there are ground jumpers on the insterment panel, I would look there. But there is no easy way to get to it without removing the gaug panel. You might try unplugging the fuel gauge wire and ground it at the tank, that will verify it is in the panel and not the sender (it is easy to get to under the rear carprt, and access hatch).

Check the fluid level in the master cylinder. If its low, the brake light won't go out. If its low, theres a good chance that you need new brake pads on the front.

These problems may be unrelated.
keith's suggestion should eliminate the brake question, as it occurred first - my light stayed on with full fluid and it turned out to need pads (although front and rear).
I don't recall anyone here having a fuel gauge problem originating with the panel gizzies -usually the gauge problems occur with the various sender bits. Petros' suggestion is a good start.
Did you perform a Search for gauge/sender problems? There are a number of threads on the subject.
