Consider me a skeptic here on this one - this doesn't sound right to me.
What type of test led you to believe the regulator failed?

Not right in my book either.

Turning over my man card...

Autozone is the one i tested the battery and alternator. And their tester displayed Voltage Regulator failed.
(Ill be buying my own equipment again now)

Took it to the Chevy Dealership, who loved the car, and they did 45min of testing and all came out good.

15.5v is the max range and I’m within that.

Best part is they loved the car and charged me $0.

Interesting, but hopefully this will help someone out if they run into similar situation. All the helpful links provided and information

Normal generator output is between 11 and 15.5 volts depending on duty cycle requested.

Aware of that now. Thanks man.

Please forget Autozone exists.

@CB750 I remember you posting instructions on how to reset window limits after a battery change, but can't find it. Seems this would be a good thread to add that link to.

So batt light on dash didn’t illuminate or service charging system when over charging due to bad regulator? I would figure over charging ie bad regulator would have shown a error But guess 15.x was still considered in range.
in no way doubting just trying to understand incase this issues arises in my future.

With all the electric gremlins that I was experiencing and the DIC readout, I didnt trust the “idiot light”. Especially after the battery/alternator tester that displayed “Voltage Regulator Failed” on the readout that I witnessed twice. But yeah, youre right the dash illumination lights would have been a better tell-tell sign.

I had a memory of my old 1979 C20 where the alternator took a sh*t and the voltage would spike and drop 15-11v erratically with electric gremlins and brought me back. (Facepalm)

The face of the autozone guy when I went back to return my core battery after I explained what the Chevy Dealer found was priceless. Interesting enough, an older gentlemen (manager) saw my car and “is that an SS?! very nice.”
Half the staff is retired military and the other half...not. Ive never had any issues with the retired folks. And they’re the ones don’t ask me “auto or manual” for wiper blades. Lol

Turning over my man card...

Dude, it happens. With all the silly mistakes I've made trying to "fix" something, my man card should have been revoked long ago. I see I will have to keep an eye on the battery voltage display from now on. I normally peek at it here and there but the DIC normally stays on the tire pressure screen for me.

Tools needed:
Flat head
Body panel puller
10mm 1/4” rachet
13mm 3/8” rachet
6” extension 3/8”

Take your flat head and gently remove the vent tube.

Now you can lift your 50lb battery out and replace in reverse sequence.

*dont forget to hook your vent tube back up.

That is the HARD way !!!
<snip>

Replace battery disconnecting/reconnecting terminals in proper order. #### If you don't know the proper sequence you should not be doing it !!!
You will have to carefully work with plastic trim tool the trunk seal weatherstrip to go over the plastic trim panel you yanked off.

Thank you @768mph and @CB750, you both provided very helpful info and I drew from each of your posts to replace my battery tonight. I used CB's method as it looked easier and 768's pics and tool list were very helpful.

Here's what I can add, and I'm a total schlemiel** when it comes to using my hands for mechanical stuff:
1. The battery is 50lbs.
2. A 'scrivet' is the fastener that holds the trunk trim in place and you'd best have the tool for removing those scrivfasteners. I had the tool.
3. Used a flathead screwdriver and shop towels to help pull off the rear trunk cover that the cargo net hooks screw into, that thing has sharp edges. When it pops loose it sounds like something broke but it was just noise.
4. If you don't know the proper sequence for disconnecting the cables, you can look it up, you don't have to bail on this project.
5. Don't get too proud of yourself for how smoothly this is going.
6. Don't try to lift the battery after you remove the strap hold-down nut, it's still fastened to the tray. It makes the battery feel like the Excalibur Sword.
7. Lift the battery out. It weighs 50 lbs.
8. Place new battery in the tray, it also weights 50 lbs.
9. DON'T, no really just don't, I strongly suggest you don't drop the strap hold-down nut behind the tray where it stops dead center under the battery tray.
10. Remove the new battery so you can try to figure out how to get that doggone nut out from under the very securely fastened battery tray.
11. Be sure to remove the vent hose from the battery before you pull out the battery because you've now pulled the vent hose out from the vent hole that's also under the very securely fastened battery tray.
12. Remove four bolts that hold down the battery tray and then realize it's still not coming out.
13. Take a few deep breaths. Refrain from taking a Fukitol pill and pouring a drink to wash it down. Take solace in that you're not yet at the point of crying.
14. Push out some plastic from the already loosened tray, remember when you took Sally Mae to the drive-in movie theater in 11th grade and find a way to get your hand under the tray to find the piece you really need. You're not sure what's under there but will know it when you find it.
15. Score!! Place the hold down nut in a very secure place where you know you'll find it.
16. Reinstall the plastic piece you pushed out from the tray, you have to reach under. Reinstall the tray fastener bolts.
17. Realize you didn't put the vent hose back through what you hope is the vent hole. Remove the battery tray.
18. Push the vent hose through what you're hoping is the vent hole, reinstall the battery tray.
19. Put the battery back in the tray. Did I mention the battery weighs 50 lbs?
20. Have a good laugh when you can't find the hold-down nut that you carefully placed for retrieval when it's ready to go back on. It will be in the last place you look.
21. When putting the strap hold-down nut on just keep thinking of it as The One Ring and telling yourself, "My Precious, My Precious". Don't drop it again.
22. Notice how you forgot to fold down the battery carry handles under the strap. Loosen the Precious Nut, very, very carefully.
23. Button everything up, notice the shop rag that's stuck under the battery. Put on the face of a Marine storming the beach and yank that sucker out.
24. Read the instructions and see that you may need a trim tool to replace the weather stripping, tell yourself 'Semper Fi' and just use your fingers to roll the weather stripping back over the plastic trunk piece.

You're done! Easy-peasy! Just a couple of dozen extra steps but hey, I saved $50 from having the dealer do it. If some monkey with a wrench is going to touch my car that monkey may as well be me! I don't need the Fukitol but went ahead and opened a nice Australian Shiraz, the vinyard is only 300km from Adelaide.

**Schlemiel. Some may remember the telecom "Laverne and Shirley" where the opening scene they said 'schlemiel, schlemazel'. Cute but most don't know the meaning. It's very simple:
The Schlemiel is the waiter who spills the soup and the Schlemazel is the schmuck customer that the soup lands upon. I was a total schlemiel in replacing my battery but it's in and I'm laughing at myself. Good times!

New Dorman part 924-253, I ordered at Autozone will be here Tuesday.

The brass fitting just needs to hold me over for two days.

I replaced my battery last week & I too snapped off the vent tube elbow 😦
The above Dorman # was the wrong part (at least for my car) the correct one is GM 92267241 it’s cheaper too.
GMPartsStore.com had the cheapest shipping charge, between the virus & the holidays it took forever to get here.

Added a pic for that part number:

Also, it appears Rock Auto has them listed for just $9 (**But shipping is another $9 though, so $18 or so. Looks like GMPartsStore nets out better)

Thanks to GXPaycheck, good2go & BillGsa’s recent comments refreshing me with Ira’s post #29. Last night, with temps getting into mid 30’s, the SS struggled to crank with the original battery. Ira’s post convinced me to take the easy route this time. I called MacHaik Chevrolet first thing this morning. Battery in stock and installed one hour later. Relieved and ready for winter. Thanks guys!!

 

[wilkin4]

Just replaced my battery with the 48AGM Delco, which was getting weak.

Took me 30 mins, and half that time was finding my tools, very simple with the directions and help provided in the thread.

Thanks guys for the tips.

I wish I had a million dollars for every time I had to replace a battery.

After making several stops today shopping with the wife, returned to the SS for our return drive home. We were able to enter the car, depressed the clutch, pushed the start button, and nothing. No lights, no trunk release, no hazard lights, nothing. Completely dead. Used the safety pull to open the trunk. I went back into lowes to buy some jumper cables and none to be found. By that time a Good Samaritan was already engaged with my wife outside. Put the cables on and, pushed the start button, and she came to life and got us home. Since getting home she has started several times. Perhaps my one year old battery on my daily driver just spoke up? What do y’all think? All I can gather is the auto door lock did not happen and I was able to enter the vehicle anyway.

Seems awfully suspect to be out driving around shopping and come back to a completely dead car. Slow crank or crank and click perhaps, but no lights, no entry no nothing seems to have happened pretty abruptly. I would pull the cover and check the connections(and perhaps the date code) on the battery to make sure all is secure. From there I'd have the battery load tested. As a daily, try to get a charge on it tonight unless you need a good excuse for a day off tomorrow.

Should the plug be flush? The dealership didn’t install one apparently on the second battery so I have nothing to go off of. If so, gentle hammer?

edit: never mind. Yes, should been flush, dummy. Pushed in with a hammer head. Not hammered.🤓
