My sons1999 Jeep Grand Cherokee had the gauges light on and would not start like battery was dead. Had it jump started and it started.When he put in park it stalled jumped again and worked.


Sounds like a charging system problem and the alternator may not be working. The gauge light will come on if the charging gauge is showing low so you will look at the gauges. Have the battery and charging system tested

Have a 1991 Buick regal,it stops charging wen I plug in temp/fuel gauge into the cluster,why would it do that?


Does it stop charging or the light just comes on/gauge goes down? Plug it in and check if the alternator is putting out 13+ volts. It could be a short in the cluster or the wire from the alternator.

Battery light alternator


The Charge lamp comes on with the Alternator fails to keep battery charge going. (lots of way to fail, and ALT Is 100% good) it's a system. each part of it must be good, end to end.
so...
i put my voltmeter across battery, i start car, i see 13.3 to 15vdc, alt is good.
no? , i see now, 12.2v. ALt is dead, (i didnt say bad) and battery is sightly discharged, 12.6v is charged. (key off, rested voltage)
This 12v tells me the ALT is shut down. only why is the question.

how can any charge system fail,
bad battery tops the list here, they LOVE to fail.
1: belt slips.
2: belt missing
3: bad alt.
4: bad wires to ALT . (corrosion on any wire or lug)
5: fuses blown , any listed below.:
your alt is not an ECU controlled, alt ,its 100% self contained

did you ever remove the ALT and blow the 100 amp fuseable link
the first step of any alt pul, is the pull the NEG, battery lug or BOOM.

im logged in to alldata.com so can you.

and what do i see.
a 5 wire ALT. one is the frame ground, so it must not be rusty or..... it fails. frame to engine block. no rust here.

wire L , yellow.goes to dash LEDs (alt failure idiot lamps) (this works)
wire. S white goes to ALT 5a fuse, is it blown?
wire :B B/G color, goes to the 100 amp link fuse. (blown>?)
wire IG Red-white, goes to a fuse marked 10A gauge.

i think the IG wire is the voltage sense wire.
no sense, no charge. I think the whole I/P dash cluster goes dead when this fuse blows.

The S wire is the boot strap voltage sense, it wakes up the regulator .
if open , the reg stays asleep, as does ALT.
Alternators can not self start, the regulator has boot strap device
that cures that. called self excitation. so this wire is critical.
All wires except the L wire is critical. in this case.

the B wire is the big wire, it charges the battery . 50amps or more..

any of the 5 paths open , kills the ALT dead.
The REG inside the ALT can also shut it down.
eg: battery bad, with huge cell resistances. total.
eg: overvoltge for any reasons. including attempts top run car with no battery, (dont ask)
eg: over current (battery cells 1 to 6 shorted) or 25 KC lamps added.
eg: over temperature shut down.

that is about it.

I have a 2002 ford ranger that got a lot of water in the gas. I have drained the tank and added heat as well as replaced the filter. When I try to start it the battery gauge goes down to 0 and all I hear...


The alternator isn't charging , check B+ voltage hook-ups on the alternator . The heavy gage wire on the back of the alternator should have B+ voltage , vehicle not running . The fuel pump has nothing to do with it > terminal 3 at the connector should also have B+ voltage , So should terminal 1 . Charge the battery an get the vehicle running , put a volt meter on the battery post's , if there is about 13 to 14 volts running it is not charging !

I have a 1993 F150 4.9 2 wheel drive, my charging system as not working. I have replaced the alternator and the system will not charge .The voltage goes up and down and when it drops it pegs my gauges to...


You have two fuseable links - one for the main battery circuit and the other for the voltage regulator which includes the stator.
The third wire goes to the gauge or warning light which "turns on" the alternator once it is running.
Does the gauge or warning light work, and have you tested the output of the alternator on the engine ?

Fuel gage not working


Charge light could be due to Alternator starting to fail or maybe loose belt to alternator. Or loose connection at alternator or at battery. Check wires along the circuit path and make sure everything is tight.
As for gas gauge, you may have a bad sending unit which is usually IN the tank or a bad connection between the unit and the dash. I'm not aware of a working gauge being a necessity for passing emissions but maybe so.

I HAVE A 2003 TRAILBLAZER IM HAVING TROUBLE WITH THE CHARGING SYSTEM,I CHANGE THE ALTERNATOR BUT IT STILL SHOW THE BATTERY GAUGE LOW CHARGE NEED HELP ON WHAT TO DO


You need to check the voltage at the battery itself, if the battery voltage is indicating in the area of 12.5 - 14.0 volts and your dash gauge does not agree, then the dash cluster has a bad stepper motor which drives the gauge.
If the battery voltage agrees with the dash gauge, and the alternator was changed and is assumed good, you need to check the wires going to the alternator, there may a broken connection.

Instrument panel went dead


Checked Every fuse in the fuse box (no small task).This includes #4 - Power point Instrument Panel, #14 - Day time running lamps (auto lamps doesn't work nor does auto lock), #27 - ignition switch run feed, #35 - Instrument Cluster, #41 - Instrument Cluster, #42 - Delayed Accessory, #45 - Ignition switch run/start feed, #102 - Door locks body security module, #103 - Ignition switch, #110 - Ignition switch, & #116 - Ignition switch. But I also check all other ones as well, they all register OK. AC panel & radio work. Turn signals work. Mileage does not work, trip computer does. So, basically, everything works except auto head-lights, auto locks, and the dash cluster (no MPH, RPM, mileage display, Fuel, Temp, Tran Temp, and Oil Pressure).

CHG Light Showing, in our 81 Corolla CS what dose this mean?


Your chg light is your charging system. It could be your alternator, battery, cables, wires etc. Generally pretty easy to diagnose with a multimeter. To check the alternator the old fashion way, you can start the car and disconnect the battery while it is running. If the engine stops then the alternator definately has a problem. This is not recommended as it is much safer to use a multimeter.
