Random dash warning lights are staying on

[2mAn]

I was driving home last night and after hitting a few bumps, the following warning lights stayed on the cluster:



e-brake

brake fluid

battery



Wanting to make sure a belt did somehow come off I checked and everything looked fine. Drove to work today, they were on, but no issues.



Same thing just now as I drove to the car wash.



Any ideas? Is my cluster about to die or did something get knocked loose?

Check your battery voltage static and charging for a start. Weird, but otherwise unconnected lights being on typically means alternator problems.

Usually means charging system is going out. Although in my case on the m42 my woodruff key on the crankshaft sheered off causing the ignition timing to be way off and i was getting combustion in my headers instead of the chamber. I fixed that and all was well.

My car had this problem when I got it. Changing the blower motor fixed it...

it's wonky ground somewhere

Car died last night, clear alternator symptoms. It died while driving, and when I tried to restart it just clicked conforming my suspicions. However once I got home it fired up immediately. Luckily I’m off work today so I’ll get under it and see if a ground wiggled loose otherwise I’m yanking the alternator and swapping it

Likely your issue. And if i was you unless the bearings are shot in the alt just buy a voltage regulator.

I bought an alternator from o'reillys. It is a reman'd bosch. Lifetime warranty and the car is back up and running, with no random dash lights on.

Hey, was it just the alternator? I’m having the same 3 dash lights come on, but only about half brightness and they go out when I rev the engine. My engine hasn’t died but my headlights and dash lights go dimmer at idle.

Yup, after the alternator was replaced I was good to go

hey I'm trying to replace my alternator too but the bottom nut holding it back on is just spinning and there is no space for me to get a tool onto it. any advice?

[2mAn]

pretty sure thats one of those blind ones that you have to feel for it.
