Trace back your installation...clean all contact points...harness wires, output wire, battery cables, ground points and make sure the installation is correct and tight. Believe it or not some alternators of gm vehicles have a printed circuit in them for specific vehicles. Just because the alternator physically mounts and fits , it my not be the correct one... check and make sure you were given the correct alternator..sometimes aftermarkets are flawed.

The car is having power drained somewhere. Check for an electrical short or some kind of "on" power source. Good Luck!!-----------------------------------------------------------------------------------

SOURCE: 1998 Monte Carlo alternater not charging

Ok, i understand that you have replaced the alternator, but there seems to be a non charge state in this case. i recommend checking the charging system. use the procedure below to isolate this issue.

Wear protective eye wear and clothing and remove all jewelry when checking your battery and charging system. Jewelry is a good conductor of electricity and is not recommended. Most batteries wear out every 3 to 5 years and need to be replaced. Always replace your battery with an equal replacement battery to assure proper operation. Automotive batteries have a +positive terminal (red), - negative terminal (black). The battery in this illustration has a protective cover over the positive terminal to prevent short circuit in case of an accident. Electricity is stored in the battery and then supplied to the vehicle when the engine is not running. While the engine is running the vehicles alternator charges the battery for future use. (Note: never disconnect the battery while the engine is running. If the battery cable is disconnected from the battery a spark can be generated which can cause the battery to explode or a major electrical malfunction to occur.)

To check a battery surface voltage, remove the positive terminal protective cover. Connect the +positive side meter lead (red) to the positive side battery terminal. Connect the - negative (black) side meter lead to the negative battery terminal. With the vehicle not running and the car sitting over night the battery voltage should be between 12.5 and 12.8 volts.(You will need to use a voltmeter for this testing procedure)

The alternator is rotated by a drive belt driven by the vehicles engine while it is running. Electrical voltage and amperage are generated to recharge the battery and supply voltage to the electrical system of the car. The alternator is held in place with mounting bolts. There is a main electrical wire on the rear of the alternator that supplies voltage to a main voltage junction box. If your alternator is not charging properly, your battery will slowly drain down from operating all the electrical systems in your car and stop the car from running.(most non charge states will be the cause of a loose belt or a low tension rate, due to a mis-adjusted alternator. make sure you have enough tension in the belt for full rotation of the alt pulley)

Next, you will need to check the alternators output with the Amp meter.

Testing the amperage output of the alternator is good for measuring the amount (not the level) of voltage the alternator can produce. This test can be tricky because if the alternator is weak it can still show it as producing amperage. Which is good, but if the voltage is low, it will still allow the battery to go dead. To check the amperage output of an alternator an amp meter is needed. Once the meter is connected start the engine. Next turn on all electrical accessories and raise the engine idle to about 1200 RPM. The alternator should output the max amperage it was designed to produce. Example: a 90 amp alternator should output about 88 amps. Note: An alternator cannot sustain maximum output for long periods of time. If the alternator is forced to operate at maximum output it will overheat and fail. An alternator is designed to operate at max amperage output only for a reasonable amount of time.

((Connect the voltage meter lead the same way you would in a battery static voltage check, Start engine (do not drive) at engine idle the voltage should be between 13.6 to 14.3 volts. If not the alternator may need replacing.)))

SOURCE: need to charge battery on my chevy venture.

Okay... One can not see the negative battery terminal so.... Connect the negative clip from your charger to the chassis and then remove the RED plastic cover in front of the black relay box above the battery OR the plastic cover from the positive battery terminal and connect the positive cable. Make sure you have good connections by watching the meter on your charger. Then plug in the charger and turn it on. Charge time depends on the strength of your charger. I'm going to go hook mine up again because I need to go out for a bit. I don't think I'm going to like changing this battery..... Just thought I'd share..... Good luck.

SOURCE: 99 Chevy Venture dash board lights and tail lights

So are the fuses getting power, they should be labeled. like tail or ctsy, or inst? The dash lights are usually 5 amps. You will need to get a wiring diagram to ck it out. but you may need to start by looking at the headlamp switch. I cant believe any GM dealer could not help you. Forget anyone from a auto parts store being any help. I can ck tomorrow when at work for a diagram.

I bought a new alternater and battery the alternater isnt charging the battery what else could be wrong


You have to check for B+ voltage at the heavier gage wire on the back of the alternator , could have a blown fusible link , plus the smaller gage wires at the connector that plug into the alternator mite have B+ voltage as well . You could look at a wiring diagram , that would show you . http://www.bbbind.com/free_tsb.html .Plus watch Test and troubleshoot your charging system Battery alternator testing

Alternater wont charge battery and fusable link on starter keeps burning


Bad voltage regulator. Usually built-into alternator.
Start car and unplug battery, if it dies your alternator is dead. Get new alternator. If car keeps running, get a voltmeter and check voltage coming through - should be higher than 12v but less than 18v. Any other number means your voltage regulator is dead, cheaper to get a new alternator.

Alternator has been removed and tested to be good, battery cables are good. the charging system will not charge any higher than 9 volts. i installed a new belt and the good battery has been fully charged....


Most Likely the Harness At the Alternater has an Open Short>> Wire BROKEN INSIDE its INSOLATER, Check for this as it Is A Fairly Common Problem with Your Discription / Symptom, This Applies to the PLUG and the Main Power Lead on the Alternater, Also Rule Our Fusable LINK INLINE With The SINGLE POSSITIVE WIRE Aff the Back of the Alternater.

99 dodge ram will not charge battery new battery they say my alternater is good alternater fuse is good


When you say the fuse is good, do you mean the fusible link. 140 Amp? See diagram below. The link is the only thing that can prevent the battery from charging. Check the voltage at the battery with the engine running. It should be at least 14 volts if the alternator and circuit are good.

Wont charge battery new battery and alternater


check the fusable link embedded in the positive wire to the altenator for an open. It is conjoined in the altenator wire that is attached to the stud with the nut equipt. The link will short out although the vinyl insulating coating will not burn or break open to see. Yug one the wire a foot away from the connection and see if the insulating wire will stretch. If so the link has an open there inside of it. Auto parts stores sells these links. They are crimped in upon replacement

Replaced battery and alternater tested fine but car will not start


It is very possible that you need a new starter. If the engine wont even turn over like its trying to start then its the started. If the engine is trying to start but wont then its probably the fuel pump.

89 thunder bird. Not charging


Did you hook up the wires from the correctly? Some batteries have the pos and neg reversed on the mounting posts. You may need to double check battery cables and alternator cables are charging. If you have a volt meter, you can perform more diagnostic tests on your own. Like testing output of alternator to ensure you are putting out the correct polarity.
