So I have an injector I pulled out of my Cummins, it ran ok but had a bit of a fuel knock, so I checked the resistance after I got it out , ohms was 0.000, I wonder if just the solenoid is bad?...truck threw no codes either
@anthonypieracci3253, Hi, 0 ohms, would mean no resistance, which would mean most likely a weak circuit. A bad selanoid... It would not control the voltage coming in.... A short would create a big number, like 1.5K ohms, or even higher. Ohms, is the measurement of how much resistance has from Point A to Point B.
0 ohms is a short, high resistance or OL is an open circuit. Like when the test leads are not connected it reads OL and if you connect the test leads together it reads 0.
@chrisvasquezsr6867, I would say, that is not a good number. Not enough resistance is a problem as well.. Just make sure your Voltmeter is in the right setting, as there are some that check resistance at different settings... And always remember, just because Ohm test comes out good, does not mean Injector is not having an internal mechanical problem. If needed, send your Injectors to a capable & reputable Injection shop, to have them bench tested. They shoild have tge "Million Dollar" Bosch machine..

What a great video thks man

0 ohms would mean the solenoid is shorted

000.3 any good? Or bad injector?
