That is the way it is supposed to work. The wire is hot and the sending unit (oil pressure switch) grounds it to complete the circuit. Either your sending unit is bad, or you do not have any oil pressure. Also, the light is supposed to come on when the switch is turned on, and go out when the engine builds oil pressure.

Thanks for your post...please read my post again......the wire is not hooked up to the oil switch......it is clear of all grounds...when the key turned on ...no light....now when i touch the wire to the case the light comes on...when i remove the wire from the ground the light stays on with the wire in the clear....my first thought would be that there is a short to ground in the wire but  if that were the case the light would come on when i first turn the key  on with the wire clear of the switch or ground ?

Light stays on? It could be shorting through one of the other idiot lights. They are all supplied voltage from a common power wire.

I had a similar problem on my 1982 CB750F. The wire was shorting out where it passed by the starter motor, which has some sharp edges. It is easy to check by removing the cover over the starter. I slipped a piece of plastic hose over the wire to protect it.

 Boy did I learn the hard way after tearing into the wiring harness looking for a short in the wire...I found a thread  on line ( Ohio Bikers Forum 2015.....Oil Lght problem ..HELP )....If your oil light stays on and it is not the oil switch...Check the Tail Light sensor located on the left side  under the  plastic side cover ...It could be bad or something as simple as your tail light bulb is burnt out................

Was that the problem? I know some bikes have a feature like that, but never heard of that on a CB750.
