Hi Caleb
Bad news. 13G plugs are not spec for over 10 seconds max at 12v. After
15-20 seconds they will be toast. Normal design behavior for them. I would
say your claim at NAPA is in the circular file. It was the controller that
was never set to allow them to run into the danger time zone. When the
controller was not correct, poof goes the plugs. That is why they came out
with temp compensated current limited plugs aka AC60G and others. You never
should have put 13G plugs in. They have been obsolete for years. But then
you knew that since it is the moral of your story :) Fun isnt it to work on
these things.
Regards
Glenn

Subject: Re: [MV] CUCV Glow Plugs
Hey,
Well I was rather ticked a couple months when all 8 of my new 13G's swelled
in my CUCV. Two weeks after I bought them, the truck wouldn't start. All 8
plugs had swelled and failed. Yesterday just for the heck of it, I bought a
13G out of the same batch from the auto parts store, and hooked it to a 12v
battery. Within 20 seconds the head had swelled. I shut it down, hooked it
up again, and next time within 15 seconds the plug had failed. Needless to
say, I wasn't impressed. I bought a batch of 60G's that came directly from
the Seattle Napa DC, and those have been in for 2 months no problems. I am
filing a claim this week with napa for the cost of the plugs, and the labor
of extracting all of the wrecked 13G's.
Moral of the story, put something besides 13G's in, 60G's seem to be ok, but
I do notice the extra power draw.
Caleb
