Battery not charging, headlight load kills engine. Test alternator output and battery state of charge.

92 ACCORD what causes the gauges to quit working when the brake pedal is depressed, another problem is turning on the headlights and the engine dies any answer's ?

Hi Christopher:
I'd be checking to make sure that the grounds are nice and clean and working properly. When you step on the brake pedal you are activating a switch that sends power to the brake lights. The brake lights share bulbs with the signals and emergency flashers, so it is also possible that a dead short in any of those components could "steal" the power from the ignition.
At this point, it's a trouble shoot game for you to figure out what is working, and what is not.
That's part of the fun. Enjoy.

Engine wants to stall when headlights are turned on ebford

Head lights draw a large quantity of power and if the alternator is not up to it then the battery has to do the job . In that case with the lights on there is not enough current left to feed the ignition system and so the motor stalls out. So have the battery load tested for a bad cell and have the alternator tested for correct out put. Check the condition and tension of the drive belt.

Car turns all the way off while driving, including headlights, starts right back up, but drives like it has bad gas, (surges), but that's not the problem

Your right, bad gas may not be the problem, but have you checked and changed the fuel filter and possibly the fuel pump? Typically if your fuel filter is going out, the cars' computer will default out and tell the engine to shut down.

When i turn headlights on engine dies on 95 lexus sc400

Is the battery fully charged?

The alternator may be bad. If the headlights reduce the voltage to the computer and ignition system, the car will stall.

I would check this first.

Good luck on this one.

I have a 2004 Ford Escape and just recently it started to stall out when I turn on my windshield wipers.

Does it do it only when you turn on the wipers, or will it also stall if you turn on the headlights or heater fan? I am asking because it is possible that the alternator is failing to produce enough electrical current so when you turn on additional high demand electrical devices in the vehicle there is not enough battery power available to operate the fuel pump or engine computer properly causing the engine to stall out.

200 Dodge Intrepid randomly stalls

Hey Brad!
So you're saying that there seems to be a relation between the headlights and the engine issue... Seems strange, but I've seen similar symptoms on a car where one of the clamps on the battery poles weren't secured tight enough (even though they did look/feel ok). Could also be that the ground wire (running from the negative pole on the battery) has a bad connection. Check and clean those first, it's both easy and cheap.
If it's not related to the battery you might have a faulty sensor somewhere. If so you should check your onboard diagnostic sensor for any codes.
Good luck mate!

Engine quits when headlights on

the headlights put a load on the engine and can cqause this, do the following and it should cure the problem.

Here are the most common causes of surges, stalls at stops, low erratic idle speed, rough idle and engine hesitation, it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
