Battery issue with my 97 Seville

Recommended Posts

Hi all. Happy Independence Day.

Unfortunately my Seville left me hanging today. 

I had not had any issues at all before last week. Last week I decided to change the battery and the negative battery cable. 

The next day car was completely dead. Weird. I recharged it and within a hour it was nearly dead. 

So I said the heck with it and put the old battery back in. Monday I left and drove 250 miles. Trouble free.

Yesterday I drove it a short distance. Was fine. 

This morning it was completely dead. Very bummed. 

Where the car is parked I do not have any of my tools, no power, etc... I managed to get the battery out of the car and have it on the charger at the moment.

I have checked the battery terminals multiple times (Still hate GM side terminals) I loosened and resnugged them. Nothing.

I think each night until I drive home I am going to have to disconnect the battery in hopes I dont strip the bolt.

Whatever is killing the battery must be a pretty heavy draw. Only thing I changed recently was  I removed the phone from the center console. Should not cause this.

Last Caddy I had that caused this issue was the blower motor went bad and killed it.  I hope that is not the case here. 

First time this car has ever left me stuck. I hope I can get home with it so I can figure it out. I still have the brand new battery although the one I have installed should be fine. 

Hope everyone Has enjoyed this fine Holiday. I will post my findings when I find some time

This should be easy to find.  Is this the car you changed the interior and console on?

I have a YT video that will make diagnosing this easy.  I used to just pull fuses while watching current draw but I have found a better way.

Good morning. I did not change the console, just plugged it back in. Verified wires not pinched under it. 

I reinstalled the battery this morning and looked for anything obvious. Saw nothing yet. I closely inspected the terminals and the lead spacer. 

It looks like I could use a new lead spacer as it has a number of pits in it from battery removals and installs over the years.

I don't want to pull too much apart until I can get the car back home. If  I can make it that far I will diag it.

I have none of my tools with me. I have everything home. I bought just enough to remove, and recharge the battery

Did you replace the seats with heated units?, maybe unplug them till you figure it out.  You mentioned the rear AC fan, what do you think?, you did say it was loud, but could it not be shutting off?

Seats were a direct swap. All heated.

fan for rear I usually leave off, it is off, but does work fine now.

I bought new terminal bolts and spacer today so that when I swap the battery again I will replace them.

I pray tomorrow it will start. I really do not want to pull the battery again til I get home. Drove it pretty good today. Voltage was always good while driving. Lowest it got was 13.3 at idle with loads

Well rest of my trip was flawless. Problem did not reoccur.

I will still be replacing the bolts and spacer.

I might add that when I replaced the negative cable (AC Delco part) the bolt had stripped before even being tight. Guess this is a telling of the quality of the product. So even though that bolt is already new it will be getting replaced anyway

Well a year later and I have to bite my tongue. This year is a test I swear.

I am done with GMs side terminal crap. I have had so many issues over the years with them.

Car left me stranded again today... 2 days before a long trip. So pissed. Been starting great.

Ripped the battery out only to find the negative battery terminal is leaking acid, rusted the new bolt and lower half on the new terminal end.

So pissed. All this was brand new last year at this time. Been starting great until recently. I snugged up the terminal bolts. I know they were tight before. 

The acid followed the threads into the terminal and ate the bolt. I am going to try to get the battery warrantied tomorrow.

I am going to bring a spare battery with me on my trip, and the tools to change it. I don't want to get stranded again. 

Alternator is working fine. 14.5 cold. 14.0 hot. only drops to 13.2 hot under full load. Cool when sitting overnight. Draw was no different than my Deville.

GM cursed us since the 80s with the side terminals. If I was not so extremely picky I would convert to different posts.

You might consider converting to a top terminal battery and use these adapters

Well battery got warrantied today. Said would not hold a load, and the leak on the negative side. Car starts quick again.

If I am not satisfied I am going to go to a DT battery and use the side terminals but add a extra ground to the top post to the engine. More ground is always good
