Usually caused by failed alternator. Remove the alternator and have it tested at your local parts store.

1996ford mustang v-6 5speed if headlight switch pull out is bad will it cause battery to discharge?


As long as the lights do not stay on, a broken switch should not drain the battery. Why don't you pull the fuse on the headlights and taillights?

see this steps and fix it use the VOM or DVOM. God bless you
The Cause: Most likely no voltage to the headlights because of a bad headlight relay, fuse, module, headlight switch, dimmer switch or wiring fault.
To figure out what's causing your problem, start by inspecting the main fuse for the headlight circuit. See your Owners Manual for the location of this fuse. It is often located in the power center in the engine compartment, but may also be in the fuse panel under the dash.
fuse1b.jpg If the fuse has blown, replace it with a new fuse (same amp rating) and try again. If the fuse blows immediately, there is a short in the headlight circuit that will have to be found and repaired before the headlights will work. If the fuse does not blow and the headlights work, problem solved (for now). There may be in intermittent short or overload that caused the fuse to fail.
If the fuse if okay, use a volt meter or 12-volt test light to check for power at the fuse. Most headlight circuits are on (powered) all the time, so there should be voltage to the power side of the fuse. No power at the fuse would indicate a wiring fault possibly in the fuse block or in the wiring between the fuse block and the battery. You'll need a wiring diagram to trace the wiring circuit and find the fault.
relay_1a.jpgIf the fuse is okay and there is power, the next check would be to find the headlight relay or control module. If the system uses a relay, pull it out and shake it. If anything inside rattles, replace the relay. Or buy another relay and plug that in to see if that restores power to the headlights.
On systems that use a module control module or daytime running lamps, about all you can do is eliminate other possibilities such as wiring faults, a bad relay or headlight switch first. If the module is getting power when the headlight switch is turned on, but the headlights fail to come on, the problem is likely a bad module. The module may be located in the front area of the engine compartment (common on Fords), under the dash or elsewhere in the front of the vehicle. You will probably need to refer to the vehicle service literature to find the module's location.
If the headlight relay or module do not receive voltage when the headlight switch is turned on, a bad switch is your problem. Switches get a lot of wear and tear, so it's not unusual for a switch to wear out after many years of service. Replacing a headlight switch can be difficult depending on whether is it located in the instrument panel or on the steering column.
If your headlights work on low beam, but you have no high beam, or they work on high beam but there is no low beam, the most likely cause is a bad dimmer switch. The dimmer switch is integrated into the steering column mounted headlight switch on most vehicles, so if the dimmer is not working, you will have to replace the entire switch.
DO NOT attempt to replace a steering column mounted headlight switch without first disconnecting the battery and waiting at least 20 minutes for the capacitors in the airbag circuit to discharge. The steering wheel will have to come off to replace the switch. Crossing up the wrong wires in the steering column could set off the air bag and cause personal injury.
If a headlight switch looks like it will be difficult to replace, don't try to do it yourself. Take your car to a dealer or repair shop and have them replace the switch for you.

I change the day running light module in my 1998 mustang and the headlights still flicker


The headlamp switch or the multi function switch(turn signal,wiper switch) is causing your problem. Find out what switch is cheaper and replace it. I've seen the headlamp switch go bad more than the multi switch.

Dash lights, tail lights, brake lights, not working 1965 mustang


Probably either a bad ground (broken wire, rust) or a bad headlight switch. The brake light circuit goes from the stop switch (Located up above the brake pedal) through the headlight switch, through the light bulbs to ground. The tail light circuit goes through the headlight switch, through the bulbs and to ground. The only things that are in common are the headlight switch (Is this the switch you replaced?) and ground.
Not much, but hope this helps.
Have a super day!
