1987 JCB Syncro Shuttle trans Low Oil Pressure Light Stays On?

Cleaned screen; new filter and new fluids. Still the light will not go out. Removed pressure switch an checked continuity; seems "OK". Tractor works well in forward and reverse.

1)The pressure switch is an earth switch, the harness may be rubbed through does the light go out when the pressure switch is unplugged.
2) Transmission mainline pressure should be at least 90 PSI idle - 150 PSI max rpm when measured at test point above filter.
