oil pressure light

[Guest]

Hi , has anyone had problems with the oil light not coming on after a run. I turn the ignition on and the oil light shows, after a run of say ten minutes turn the motor off and on again the oil does not work ! remove oil pressure switch refit and the light works. I have fitted a new switch, same problem. The oil pressure switch seat in the crank case looks fine. I have checked the oil pressure at the gallery plug and no problems there, the pressure is as per the book.

thanks Lionel

it might help us if we knew what bike you are referring to.

If you have tried a new switch, then problem is likely in wiring or gauge cluster itself- oil light might not be getting 12 volt positive at times- bad bulb contact,etc.

Hi Agemax,
sorry the bike is a 1980 GS850G.

tom203,
one thing I have not checked is the continuity through the switch when the light fails.

Clean the inside of the engine case where the switch grounds out.
