Need Help SW Missouri - Glowplugs

[papakb]

A good glow plug will only read a few ohms on the meter so you'll want to be on the lowest resistance range.

No clicking / cycling on later solid state controllers. Look for the dash voltmeter to dip while cycling... That's if everything is working correctly.

When using the meter touch the "bullet tip" and the hex. I don't rember what ohm's to expect. But you can compare the readings to the new plugs you have. All 8 should be close to each other. I wouldn't be surprised to see one or more open line. That would be the burn't ones. Also remove the engine cover. And from the drivers seat. Remove the rear drivers side glow plug connector. Using you multi meter connect to that glow plug wire and the ground. Then turn the ignition switch to run. See if you are getting 24 volts there to the plugs. Is the wait light working? Are you hearing the clicking of the glow plug solenoid?
