glow plugs ???

how you test one

[potif]

just disconnect the common + strap from the top of all plugs then use a test lamp conncted to the + terminal of the battery and the top of each plug - one at a time. If the lamp lights up, the plug is good. you could also use a multi-meter to check for continuity between the + terminal of the plug and the cylinder head - once again continuity means that the plug is good

take it out and connect it to a battery ........... If you suspect them change them , make sure that you put them back together correctly with the insulator in the correct position , or you will blow the 80 amp fuse


also make sure you can hear the relay clicking when you turn the ignition on

Now here's the proper way to test. Remove them all and test continuity with a multimeter. Resistance should be less than 1 ohm.
