Half failed glow plug?

Well, since the starter burned up in my truck, I decided to actually change the glow plugs. Eight nice new Berus put a good dent in the budget, but they are better than the Autolites that came out. I tested the old ones on my jump start pack, and it was pretty sad. Two glowed nice and quick, two started glowing after three or four seconds, two were flat dead but two were odd- They would get warm at the tip, but still cool enough to handle.
Has anyone seen a partial failure like this?

A couple of glow plugs I took out of the camper few years ago were like that.

Testing them with a meter, they tested ok, but once pulled out, and tested directly on a battery, they would only get warm, not glow.


Some were Autolites, some were champions, some were bosh.


Hate to say it, but the camper and 7.3 both have mixed matched plugs, of all kinds, never had a problem with any of 'em.

Are you sure the jump box wasn't just run down? It would be interesting to see how they test with an ohm meter and the test light method.

Nope, these were a couple of the first ones I tested, others glowed afterwards.
The battery in my meter died so I can't properly test them but they haven't hit the scrap pile yet, so as soon as I get another battery I'll test them.
It was just going straight to rapid cycling so I new at least a few were dead. I have no info on how old they are, but this thing has always started a bit hard.
