Cliff:
I suspect that your oil pressure switch is mis-wired. The
correct operation is that the brake light is on brightly, and
the oil pressure is on dimly with the ignition switch in the
"run" position, but with the engine not running.
When the engine is running, oil pressure will cause these
lights to turn off if everything is fine.
There are three terminals on the oil pressure switch,
and three wires going to it. It is possible to get the wires
swapped around and have the lights stay on even if the ignition
switch is off because there is a lead on the oil pressure switch
that is live.

Subject: PDWA Oil switch
Troubleshooting my brakes I was visiting the PDWA
switch. I found that the brake light is on
brightly and the oil light dimly, the problem is these
lights are on when the key is in the off position. In
the on position the lights go out. I have a ' 73. I
have Dan Masters book and the diagrams confirm this. I
am pretty sure the PDWA scuttle is tripped but that
doesn't explain the why the lights would do this. I may
have a couple of things going on here. I thought the
ignition could have a wire mis-placed ?? but the entire
electrics are fine except this?
Any ideas?
Thanks
Cliff
