Battery light and "Brake" on dashboard problem

Dec 03, 2006 5 Replies

Hey guys! I have a 2000 Mitsubishi Eclipse GT. My car was running fine until yesterday (no warnings, etc) that I gave it to a person to do a paint job on it. When I got the car I noticed that the Battery light was on as well as the Brake warning light in the panel. Also I noticed that my radio was reset to default (which gave me a hint that the battery got discharged at some point). I read in the manual that the brake warning light might mean that the brake fluid needs to be refilled, however I checked and everything is fine. The light is on still. Also when I took the car to check for the brake fluid and shut it down, and then tried to start the engine, the car wouldn't start (the battery died). I got some assistance to start the car and both lights stay iluminated. If I accelerate the car to high RPMs then the lights turn off but as soon as the RPM is back to idle or normal RPM for driving around the lights stay on. I had the alternator checked about 5 months ago and some parts were fixed. I am thinking that the battery will need to be changed for the lights to be off completely. Am I on the right track? I don't understand why the brake light is on if the fluid is ok and brakes seem to be fine as well. Any suggestions are welcome. As always thank you very much for your help.

Absolutely correct.

The alternator is not working or possibly just bad battery connections.

Probably not, Check battery connections and alternator.

This is 100% normal. Stop worrying about the brakes. Even without a fault, the brake warning light -- and on some cars other warning lights as well -- is on with key on and engine off so the bulb can be checked. The bulb check is turned off when the alternator kicks in after starting the vehicle. If the alternator does not kick in the brake warning light stays on.

Beware of cheap rebuilt alternators that are frequently defective out of the box. Best bet for reliability is probably going to be pay the price and go with Mitsubishi's rebuilt. If you can find a "Denso" brand rebuilt you can take that to the bank also.

You might want to try checking to make sure the e-brake is completely off. Sometimes body shops use the e-brakes to hold the car in place, and may not have completely released it. It also sounds like you need a new battery.

Not really because if that were the case the light would not turn off when the engine was revved as he reported.

Battery warning lights usually refer to the charging system, NOT to the battery.
