Question about 1998 Ford Mustang

2 Answers

I wrote in about the 1998 Ford Mustang GT and the issue I was having with the lights flickering. The volts go up when I stop at a stop sign and then the volts go back down when its idling. I pulled one of the wires off of the alternator and there's a clip that holds the wire on. One of the clips is broken and I am wondering if that could be adding to the problem of the headlights flickering!? The answer I received before, stated that it could be a ground wire. I just want some opinions, suggestions etc. Thank you.

Any wire problem on an alternator would cause a problem with the power to the charging circuit, high and low drops in power and on am frequency on a radio you will hear a humming with the engine running. good sign alternator damage. falty earths are another cause of flickering lights and power problems.

Try a jumper lead from battery to alternator body in case the fixing bolts are dirty caused by corrosion ,this depends on where you live of course ,failing which change the alternator as the builtm in regulator is faulty and its not a weekend mechanic repairable item ,their is nothing else that would cause the fault you describe.

SOURCE: 1998 Ford Mustang Headlight Adjustment

The adjustment screws/nuts should be located either on the top of the headlamp assembly, behind the headlamp assembly, or near the frame rail by the radiator support.

You will have vertical adjustment screws for each independent beam (separate highs and separate lows, but will be same screw if highs and lows are the same bulb). You may also have additional horizontal adjustment screws as well

Park your car on a level ground 30 feet from a wall and measure the height from the ground to the bulb and mark on a wall (do this for highs beams and low beams if the bulbs are separate, if highs and lows are the same bulb, only do it for the lows)

For Low Beams: If the headlights read VOR, then aim the brightest part or cutoff part just below the mark on the wall. If it says VOL or nothing, aim them 2 inches below the mark on the wall.

For High Beams (if separate from low beams): Aim the headlight directly at the line you marked on the wall.

Below is your wiring diagram. So does the battery run down or not? At 12 volts, the battery should run down. Here are a couple things to check. The grey 20 gage fusible link from the battery to the alternator runs the stator coil. You could try jumping that with a regular 14 gage wire to see if the voltage will jump up (should be at least 14 volts). The other thing is with dual batteries (which I think you have), if one battery is bad, it could pull down your voltage. Try unhooking the negative terminal on one battery at a time to see if the voltage increases. Let me know if you have any questions.

Brake lights stopped working 1998 mustang


Fuse panel is under the dash also as I have found with my own graceful daughter, there is a brake light switch that connects to the brake pedal itself. It is hard to get to and even harder to see but a lot of times these switches get bumped and they can not make connection when the brake pedal is depressed. Hope this helps

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.
