Serious Advice Needed

[BEE STINGER]

I'm having some electrical issues. I currently have a 2020 Kia Stinger GT1, 67k miles. We thought it was battery issues. So I had to remove everything from trunk to get new battery replaced. The battery was replaced and isolator was installed to help with drainage. Got the car back.. Took it for a drive and it showed no issues over the weekend. Now driving to work, the panels on the dash started to flicker on/off. I arrived to work and not the battery is completely dead. We were able to jump start it, drove it like three blocks. Now battery is completely dead again. Any suggestions??? I pray its not the alternator .....

Just noting that this topic has been moved out of the community lounge and into the main Stinger talk forum.

I would say initially it was a battery issue and replacing the battery would have resolved the issue. But if some damage was done installing an isolator then it could well have damaged the alternator. Your symptoms seem to indicate that the battery is not charging at all.

So best to say, install new alternator

check alternator and battery fuses first before you commit to a new alternator. given all you've installed there, something could have shorted.

Do you know where all the fuses are?

search through my old posts, i've posted this a couple of times already. there's one in the main fuse panel under the hood and i think there's another in the battery area. they are huge, screwed down fuses, not the little ones you pull off with the little tool. there's also one for the alternator in the main fuse panel as well. since your accessories are running and draining the battery, I would check the alternator fuse first.

uhm no........

It requires the whole engine dropped out to access the alternator.

You do not want to have to change the alternator if you can avoid it

The simple test is to check battery voltage with a multimeter with the car off. Is it 12.x? Then run the car and check the leads, does it jump to 14.x? We have an ECU controlled alternator, maybe see what OBD says as well.
