Recently I noticed glow plug light not on anymore. still starts, but with dropping temps here in GA, it DEFINITELY stumbles until warm.

I have the 3 pdf's from MB that say how to test all the electrical stuff.

Rather than go through all that (cuz I suspect its a faulty GB - its got 248k on em!) is there a quick and dirty way to see if the plugs are getting hot?

Can I just touch the threaded end to see if they are warm, or will they get to a billion C at the exposed end ? Dont wana burn!

I guess I could pull all 6 plugs out and go key on to see if they all glow. Replace one that doesnt. Except getting the plugs out looks like a pain, intake prob has to come out.

Any help here would be much appreciated!
