Are you sure the switches are good?  Are they correct?  Have you measurd the
oil pressure?  Are the wores connected properly?  Switching the wires to the
sensors will cause erractic operation.  Except for wiring and switch
problems, I have not actually seen this circuit fail.  I have seen legitimate
resons for the light  and buzzer to come on.  Especially after the engine
warms up.
