problem with gauge cluster. vid. help.

[Diamond Star Werks]

Okay so lately my car has devoleped a weird problem with the cluster. The brake light battery light and low coolant light are coming on sometimes dim and sometimes strong.

When I rev the engine the lights go away. When it drops down the lights come back on sometimes and other times they will stay off. Any help would be great. Also the gauge lights will dim when i turn my signal on and my fuel pump will go up and down as well. It has been rewired though so i don't really understand why it does that. But the gauge lights won't flicker when I turn my hazards on or press the brakes. uploading a vid in a minute.

I've had a few cars with the battery/charging system light on that turned out to be alternator/relay/fuse related. Check the alternator fuse, and have the alternator and battery tested. As far as the low coolant light, have you checked the fluid level in the reservoir?

I forgot to say I have checked the alternator and it was working just fine. Its all three lights at the same time. I posted a vid that will explain.

sounds like a voltage output problem at idle. Did you have the Alt. load tested?

 

[Albrecht09]

Its your alt. It may be, and probably is, still working fine right now, but it is on the last stretch of its lifespan. How long will it last? Depends, do you have a bunch of electronic stuff running in your car? Like aftermarket radio, speakers, amps, subs, lights, whatever?

 

[Diamond Star Werks]

No I just have four 6x9 speakers a radio and small LED strip above the pedals which is off 99% of the time.
Like with brights of it charges13.5 ±.3 brights on12.55 if I rev it just alil it goes back to13.5v. My car is starting to idle lower than usually too. Like instead of 950 its close to 700

As others have stated the alternator is on it's way out.

 

[Diamond Star Werks]

if it was the alternator going out and not charging correctly wouldn't it just flash the battery light? That is the purpose of the battery light. Any have a ground diagrahm? I no longer have access to alldata

 

[bryanwheat]

This is super common on these cars. As i said, your alternator is going out.

 

[donniekak]

Get a new alternator.

Correct it was the alternator. Thanks for the help.
