My 90 4runner has the brake and battery light on. The power is going in and out and sucking the battery dry.whats the hell is wrong?

I have the emercany brake and the battery light on in truck. I have had the alternator and the battery tested and they both pass. When I'm driving the lights will be bright one minute then the next will be so dim that I can barely see the road. The brakes work great and I don't need any brake fluid. Now the battery gauge is jumping all over and being drained within 2-4 hours. Someone told me it was a short between the battery and alternator so I checked that and I seemed fine.

There is a problem in the charge circuit and it indicates a short in the system
could be in the alternator or voltage regulator or if the voltage regulator is in the ECM , the ECM itself
If the alternator was not removed and bench tested , any wire problems would be revealed and the unit not properly tested
check for bad ground wire from the battery to the engine

SOURCE: Right tail light not working when pressing brake w/ lights on.

There should be at least 2 bulbs in the light assembly. One light is the light that is on when you turn on your headlights with out the brake pressed, the other light only lights up while you press on the brake. Make sure you are replacing the correct bulb. You may have been replacing the bulb that stays on. Your lights may be set up to turn off the light that stays on when the headlights are on while pressing the brakes.

SOURCE: 2005 Corolla LE brake lights not working

to ss1957, i have exactly the same problem as yours. At first i thought the bulbs of both side are okay because the filaments (there's two on each) are intact. It turned out that they're not. The brake lights came back as soon as I replaced the bulbs.

SOURCE: Toyota 02 is stalling, won't idle

Check the voltage of battery with voltmeter.. It is sometimes possible that if voltage of battery drops and jump start is needed, your computer will only charge to the last voltage that was recognized which would be when jumped...Try and charge the battery if possible I would actually suggest that you have your battery tested at local auto parts store and if it is presumed in good condition ,let them charge for you to max capacity . If battery has been tested and labeled as no good replace if necessary... Oh, and first thing you should do is make sure your positive and negative battery connections are clean and tight...if this didnt fix problem please give more info on what was found when advice above was followed...Good Luck!!!!

SOURCE: 2003 Toyota Camry - Both Brake lights not working

Lok in the trunk on the left side, behind the carpet for a small plastic box with a bunch of wires going to it. Look to see if there is brake light powe coming in with the pedal depressed. If so, and no power is coming out, you need to order and replace the "taillamp failure sensor".

SOURCE: when push brakes you have to push really hard to

Sounds like you will have to bleed your brakes again, but thats not the problem og hard brake peddle, need to check your power brake booster, sit right in back of master cylinder, check make sure it has vacum going to it, also to test it with engine off, press on brake peddle three time, then state engine with foot on peddle, peddle should go down a few inches, also with engine of peddle should feel soft for three pumps, if you have none of this , power brake booster is bad.

No start or no crank. no radio no radio ,power locks ,headlights or brakes light.

Have you checked the battery? Are you sure everything is connected/? If you can't get it to start because you have no juice but have a new battery, then that's a problem. Or something is draining the hell out of your battery. Check the fuses.

My brake and battery lights are both on my 2008 nissan maxima will go faster than 40 mph, what is wrong?

Battery light on may mean alternator is not charging, thus engine is running off only battery power = weak spark and bad curent to ECM. Fix battery issues and should run better. Brake light separate issue I think.

Tail lights not working

All of the marker and tail lights are powered from a 15amp fuse going thru the headlight switch on a brown wire. Do you have power from that circuit coming out of the headlight switch ?

The marker lights, brake lights,dash lights,power windows,power locks,radio and heater dont work

When you release the brake pedal, there is a switch underneath the brake pedal that disconnects the circuit to your brake lights causing your brake lights to switch off. Sometimes this brake light switch will go bad and need replacement. If your brake light stays on after you turn your car or truck off and you don't want to run your battery down, you may be able to get down underneath the brake pedal and manually pull up on the brake light switch to deactivate it until you can get it repaired.
and i think you can make a diagnostic by yourself and the Autel MaxiDAS DS708 can help you

I replaced the battery and now my Brake, ABS, VSC trac and VSC off lights are on with a warning sound constantly emitting and the brake pedal does not work. I push it all the way to the floor and nothing...

No, your brakes should have a stiff pedal regardless of anything going wrong electrically in the car. You better look for brake fluid leaking out. Try not to let the reservoir run dry while you're looking for the leak, as that will introduce more air into the lines. Let us know what you find and if we can help any further.

There was a light that came on on the dash that looks like a battery and the brake light came on also and now my battery keeps going dead

A likely factor is that an issue with your brake system is drawing power from the battery, I would suggest going into your local dealer to have them find out exactly whats wrong instead of wasting time and money on random fixes.
