should be continuity. With engine  running, oil pressure 
should open switch  and there should be  no continuity. Re- 
place a  faulty switch. 
CAUTION- 
Keep in mind  that low oil pressure  may be preventing  the 
switch from turning the  light out 
If the light  remains  on while 
the  engine  is running,  check the oil pressure  as described 
earlier. Do not  drive...
