Was not uncommon to read this way on some GM products. Its ok. Now if the head lights pulsing while engine is running Alternator is going bad. Should have alt replaced and Battery checked. There are Diodes in the alt and when 1 or 2 go bad the pulse you see is alternating(AC) currant going through you direct current (DC) system. Can mess up a battery if not cought soon enough

SOURCE: passenger side power window wont roll up

The problem may be in the wiring which if you pull up the carpet on the front passenger side by removing the door floor trim and lifting the carpet you will see the wiring underneath. Probably laying in water or has been. Look for splices in the wiring which will have corroded. Repair the wiring then check the fuse.
Another problem may be in the motor found inside the door. The brushes may have worn out. If so you need to replace the motor. Ususally the drivers side will fail first since it is the most used.

SOURCE: Gas gauge is moving back and forth.

hello! there, fuel gauge not accurately reading or registering your actual fuel,this can spend costly so much on refueling of gas due to worries on drying of tank.there are factor to check on fuel sensor this maybe malfunction,or check the fuel lever sensor this was located on your fuel tank,This should be done on car service center
not by yourself this is due to hard work besides fuel is flammable in small spark of igniton by a certain object.be sure to take all necessasry precaution on doing this.so its beteer qualified mechanic to this.thanks and regads..

I put a new alternator/battery in my 02 jeep grand cherokee limtid and now my batttery gauge keeps moveing back and forth . whats causeing this?


what engine option????????????????????????????
that dash meter is a volt meter.
so when that meter varies
connect any hand meter, DMM (volts) to the battery lugs
do both meters vary,?,, yes, BINGO its not fibbing to you, the
voltage is out of control. per below:
but key on volts is 12.6v
and running does vary from 13.3 to 15v, this is NORMAL
outside that range is AB-NORMAL.(running)

post actual accurate voltages. and we cant find true cause.
is engine RPM always above 800 rpm
is the alternator fan belt at spec, tension?

if engine RPM drops , way low the ALT drops.
if the belt slips ,same deal.
My 4.0L uses a serpentine belt that must be set real tight.
100lbs. in fact. i have a spec tool to do that. (guessing dont work)
tell engine on 02 GC and we can look it up.

Battery gauge moves


check for belt tightness it sounds like the belt is slipping or the idle rpm is too low (near 500) to keep the alternator suppying enough power to run the car(or it is too small amperage alternator for the car anyway..) get tested for free at autozone or parts store..

2004 jeep grand cherokee will not start, dash light blink , gauges move back and forth. Battery seem to be ok.


It takes very little voltage and amperage to operate dash gauges. You cannot rely on "seems" when it comes to the battery. A good battery should have standing voltage of at least 12v and be able to "snap back" from a fifteen second 200 amp load. Under load, the voltage should not drop lower than 9.5 volts. Have the battery charged and load tested before going anywhere else with this. then make sure connections are clean and tight. After you get it started, if battery was good, check starter draw and charging system operation. If it does not start, check power flow from key through neutral safety switch and starter relay to starter.

First off, add a new ground wire from the engine to the body just for the hell of it. Now clean all the battery cable connetors aat all point and add WD40 afterwards. Also check connectors from dash panel to engine circuits. This is real suspect. WD 40 them also

Fluxuation in electrical power


This is normal behavior in Grand Ams. I've had a '97 and a '04 and both did this from day 1. You'll also notice the lights dim/blower slow down more if you press the brake pedal while idling w/ blower on high and lights on; it's just that the alternator on these cars can't output anywhere near full power at idle. (my '03 S-10 also does this). Watch your voltmeter if you have one, when running above 1200 RPM you should see the system running between 13.5 - 14.5 (usually you just have to eyeball this as the gauges aren't well marked, mine are only marked 8 & 18 - should read slightly past halfway). If you're still worried, have someone check the system for you, many places like Autozone or Advanced will do this for free.
