Perkins M30 (Volvo 2030) wiring

[shep65]

Hi, I have a Perkins M30 (Perama). Can anyone share a wiring diagram that includes the control panel and the harness from the engine please? There are two - what appear to be - diodes connected into a 'chocolate block' connector. Can anybody advise what these are for please?
Also, the oil pressure light won't go off, though engine runs fine. Should the light go off if the wire from the oil pressure switch is disconnected? Thanks

A Google search will bring up a wiring diagram. Have you looked if the oil pressure sender wire is connected? It's under the heat exchanger on the top left hand side of the engine as you look forward. The light will stay on if it's disconnected

Surely the light will not come on at all if it is disconnected from the sensor.

Good point, I'll check on mine tomorrow
