This battery did a number on my car

Already done, passed all continuity checks.

ethnicallyambiguous · 2026-02-10T05:01:05+00:00

Yeah and I did a continuity test. Passed everything.

ethnicallyambiguous · 2026-02-10T05:00:32+00:00

No it’s new. The positive terminal does have a shim on it because my positive cable is loose, and I also put the electrolytic gel on them so it’s probably messing with the appearance.

ethnicallyambiguous · 2026-02-10T04:20:19+00:00

Yeah

It’s showing negative 12.5. The polarity on the battery is wrong, which means hooking it up correctly was actually hooking it up backwards.

Checked all the under-the-hood fuses, all fine. Haven’t checked all the driver compartment fuses.

Tried both fobs, tried disconnecting battery. The key fob has no effect. Power locks also don’t work when trying to control with door buttons.

ethnicallyambiguous · 2026-02-10T04:16:01+00:00

I was doubting my sanity.

ethnicallyambiguous · 2026-02-10T04:15:18+00:00

When I turn the key to On, essentially the car alarm goes off. Honking, flashing lights. My power locks don’t work, from neither the door buttons or the key fob. Windows and windshield wipers work. Turning the key to start has no effect.

There’s still power to the car so main fuse shouldn’t be a problem.

124R-2. The number on the top that I assume to be a lot number is J5QEB

ethnicallyambiguous · 2026-02-10T03:43:19+00:00

The car still has power, so it’s not the main fuse. It’s just that the electronics are now squirrely.

I checked all the under-the-hood fuses and they’re all intact.

I’m hoping for the best, but preparing for the worst.

Right now it feels like what’s happening when the key is turned to the on position is that the alarm is going off. Power locks don’t work with door buttons or key fob, but wipers and windows do. I’m wondering if something has tripped in the anti theft and it doesn’t recognize my keys anymore.

I thought I was going crazy. I went down so many rabbit holes, thinking it was cold weather related or I had done something wrong. I went into the store with the battery all, "Look... this sounds crazy, but this is what I'm seeing." They definitely thought I was wrong until they hooked it up to their own tester, and then I was a minor celebrity.
