Single terminal oil pressure switch for Rover SD1 V8?

Post by alc59 » Tue Apr 02, 2019 5:33 pm

In my Grinnall Triumph TR7 which has a Rover SD1v8 engine the 3 terminal oil pressure switch has failed - it's weeping lots of oil.

It only has two wires going to it, so I have in mind to replace it with a one terminal switch, because the 3 terminal switches are difficult to get and expensive. Can anyone let me have the part number for a one terminal switch that will fit?

Thanking you in anticipation for your help
Al

The three terminal switch controls the fuel pump on the SD1. Later carb cars did this with a single terminal one and a relay. The injection versions also used a single terminal one.
