testing needle lift valve in injector

Madmark · 25-01-2016, 08:03

Can some one explain how to test ohms on the injector sensor to see if mine has failed. But treat me like numpty as I know very basic electrics but not when it comes to testing ohmage I have a good circuit tester to hand so what setting and what wire do I test from injector and engine running or not. Give me an engine ill rebuild it but electrics are witch craft to me

Engine needs to be off your meter wont be impressed if you are testing ohm's through a circuit that is carrying a voltage.
