Replaced battery, car starts and runs but no electronics work. - Infamous Nissan

Tetsuichi · 04-29-2022, 12:17 AM

Last night I left my headlights on and killed my battery. I tried jumping it a few times to no avail, and decided I would go out and buy a new battery since this one was several years old.

I replaced the battery, car starts and drives fine, but now none of the electronics work, other than the headlights and wipers.

Radio, dash, horn, brake lights, heat/fans, 4-ways, nothing works. I checked all the fuses and they seem fine, and i can't imagine they would all fry at once. Is there a main fuse or something that I might have blown while jumping the truck?

popped one of the fusible links at the battery.

agree on fusible link, get a test light and check for power on each side of each fusible link, do not replace with a regular fuse, it's not the same.

Solved: you guys were right it was just a fusible link, replaced both with an oem set off ebay. 🙏 Thanks a lot!
