Eric,
You don't have an "open" you have a "closed". The switching on these is low
side to ground. The 12 volts goes through the bulb and then to what ever
switch is appropriate. In this case I suspect you'll find that the cutoff
valve contacts are stuck closed turning on the light.

Subject: Oil Pressure Idiot light on '76 TR6
Strange question follows:
I pulled my '76 TR6 out of the garage for a much needed run to my local
Triumph Club Board meeting last night. When I connected the battery (I
leave it disconnected during prolonged storage), and before I put the key in
the ignition, the oil pressure idiot light was illuminated. I put the key
in the ignition, the IGN light turned on. Once the engine was started, both
lights went out. I had oil pressure on the gauge, so all was well and I
wasn't concerned.
Upon pulling into the parking space at the meeting, I turned the '6 off, and
the oil pressure light turned on again. I obviously have an open circuit.
Now, I check the oil pressure switch on the block and pull the white /
purple wire that goes to the electric cutoff valve that resides under the
carbon canister. The oil light goes off, and no longer comes on.
Question is: I'm guessing that my cutoff valve was stuck, or was / is
faulty. Perhaps a winter layover caused the problem. Anyone want to chime
in with other thoughts on the problem?
Thanks,
Eric Conrad
