Question about 1995 Oldsmobile Aurora

1 Answer

Electrical problems. We got new alternator; problem still exists. Instrument panel indicates that sometimes battery isn't being charged; that oil & ATF need immediate change; I noticed headlights & most electrical accessories will stop working & will come back on randomly for long periods of time; battery is frequently being drained; brake light always work though; maybe a short somewhere. We've put a lot of money into it, but problem not solved. Please help!

2006 ford escape xlt. New alternator.New batteryWon't stay started while blinkers,heat,air and radio are in use..lights inside bright...lights on dashbooard very dim.PLEASE HELP VERY LITTLE MONEY


Is the charge indicator lit , or battery symbol lit on the instrument cluster ? The charging system on your vehicle is computer controlled . Do you know how to do automotive electrical system testing ? Test for B+ voltage at the alternator connections . Heavy gage wire on the back of the alternator should have B+ voltage ,plus pin #3 at the connector should also have B+ voltage . Your best bet , take your vehicle to a qualified repair shop .

2007 Denali won't hold charge. Replaced alternator and checked battery. Will run for a while then all of a sudden just won't crank. Jump off and it will run for a little while before it does it again.


2007 Denali ? GMC Yukon Denali ? doesn't matter , it's not charging ? before replacing the alternator did you have it checked ? Is there B+ voltage on the heavier gage wire on the back ? Is the battery light symbol lit on the instrument cluster ? This charging system is computer controlled .
Electrical Power Management (EPM) Overview
The electrical power management (EPM) system is designed to monitor and control the charging system and send diagnostic messages to alert the driver of possible problems with the battery and generator. This EPM system primarily utilizes existing on-board computer capability to maximize the effectiveness of the generator, to manage the load, improve battery state-of-charge and life, and minimize the system's impact on fuel economy. The EPM system performs 3 functions: Your best bet would be to have a qualified repair shop test the system .

99 Blazer V6 4x4 Intermittent start problem New battery Alternator? good Start a few times then won't, no sounds/lights Voltage read low Charge battery and it's good for a few days Any suggestions


When the vehicle is running check voltage at the battery . should be 13.1 to 14.1 volts , if not the alternator isn't charging . Doesn't matter if the alternator is new , has to have B+ voltage on the heavier wire connected to back of the alternator . The other wire connected to the alternator comes from the PCM/ECM . Is the Battery symbol light on when vehicle is running ?
The powertrain control module (PCM) or vehicle control module (VCM) turns the generator ON or OFF, by applying voltage to the generator control/monitoring circuit 225 (RED). The regulator in the generator also requests the charge indicator located in the instrument panel cluster (IPC), using the same circuit. When the regulator monitors that either a voltage high or voltage low condition exists with the engine running, a ground path to the PCM/VCM will be provided through the generator control/monitoring circuit 225. The PCM/VCM then sends a serial data message to the IPC requesting the charge indicator to be turned ON. The IPC monitors serial data messages from the PCM/VCM, and turns the charge indicator ON when requested. It mite be best if you take your vehicle to a qualified repair shop , unless you like making parts stores rich , buying unneeded parts .

Bmw x5 battery light stay on


Check your manual for what the battery light indicates. It is just a general light for the electrical....not always the battery.

sounds like you need to have the alternator checked, if it were the instrument cluster the van would still run, you may still have a problem with the cluster, but the running 2 miles and the battery going dead is the charging system, you may have two problems. fix the charging system first then worry about the dash.

Your battery is suspected to be low in power But check if thegrounding of the battery is tight and the positive terminalis also tight.If not put your battery on charge.
I understand that you are takinga whole lot of trouble to do this routine of charging and connecting.I must advise you to disconnect the drain voltage circuit like the remotecontrol or the car system.connect them to a main switch and put it off in the night.If you cannot rectify the fault of these units.Now after the battery is charged crank and start the engine and measure the charging voltage.Check voltage of alternator to the rectifier regulator module.If charging is low this unit can be defective.If so replace.

Instrument panel battery light, what indicates?


It indicates low or too much voltage. It's either a low battery, a voltage regulator that is going out (it's built into the alternator), or an alternator that is not charging the battery back up. If you know for a fact that the battery is good (not old and it holds a charge ok), pull the alternator and take it to a local auto parts store. Most of them will test it for free.

Volt light


Volt light - on instrument panel usually would indicate you to get a battery. If you can get your car started, take your vehicle to any auto parts store that offer free electrical/ charge check just to make sure. It also could indicate a regulator in your alternator not holding charge either. If your battery is not a maintenance-free type, carefully remove the caps on top of the battery and check the water levels. Be sure to only use 'Distrilled Water' if needing to add to your battery.
