Re: [diesel_mercedes] Re: GLOW PLUGS??

 

I usually pull the plug in the relay box and check each contact  to ground.  If it's grounded it's good.  Just be sure that you're testing the right ones, there are 6 contacts and obviously only 5 plugs. Also look at the fuse in the  box.

Ten great Nate answers,
Nine kinds of fungus growing,
Eight cylinders firing,
Seven Dash Cracks running,
Six Climas cooling,
Fiiiiive compressssssion rings...
Four oil drips growing
Three half shafts clanking
Two mono valves sticking
And a vacuum leak in my one twenty three...
