Blowing Glows

[Hink]

Hey all,
I'm getting ready to put in another set of AC Delco 60G's. This will be the third set in under 2300 miles.

What conditions would burn them out?
Head gasket had blown and flooded a chamber? Too much anti seize and not grounding well?

I'm just throwing crap out there now cause I've always known 60G's to last.

Any ideas?

 

[MrMarty51]

Condition of low voltage ?

Condition of low voltage ?

Hmmm...
So that would have to be confined to the glow system itself since it's turning over fine, yeah?

And what voltage, exactly would I be expecting to see when testing?

Are you buying your glows from the same place every time? Any chance they’re counterfeit ACs?

Did they blow with a rust like texture on the tips? If so timing is too advanced somewhere in your tune.

Amazon, so could be I guess.
They are stamped AC Delco and other normal things so I don't know how I could tell.

No sir, they look brand new.

I guess I should clarify that they didn't blow as in the tips are gone but just not working and test bad.

Try a set from NAPA. Amazon is where most the fakes are at.
Good to see you around- been a minute.

Should be near battery voltage with all the GPs disconnected.
Also, how snug does the terminal plugs fit the GPz ?
I think the Amazon GPz might be the culprit but You still want to check the condition of the GP harness.
Also mentioned that the GPz quit working but look like new, is that tested with jumper wires from a 12 volt source, as in a wehicle battery thats full charged ?

Thanks Will!
Hit a real rough patch but I hope to get back on top of things.

I'll try a NAPA set, hopefully they aren't a million dollars yet.

I've got a PT Wiring Solutions plug harness that's in good shape but I'll check the ends.

I just tested for continuity, didn't figure anything else needed to be tested if it was zero.

That should be good to go.
Still should check voltage on a couple of the terminals to be sure that the GP relay is not goofing off on You.

Copy that, I'll git 'er dun.

Report:
NAPA has 60G's for about $11 so I got a set. Warranted for 7 years and unlimited miles which makes the extra cost more than worth it. Especially if this is a manufacturing issues and not a counterfeiting issue.

After install, she absolutely jumps to life. And after recently installing a Powermaster Starter, Verlin Martin 120CC pump, and Harland Sharp 1.5 rockers (I gotta update my sig), she just purrs.

Well, she purrs like a drunken loudmouthed sailor anyway.

Now we'll see how long they last.
