Well, it can't read "0" when the car is running unless you do not have the wiring harness connected to the large post on the alternator-the battery has to read something over 10 volts to run, so you probably just have a bad alternator, remove it and take it to and auto zone, advance auto or pep boys so they can test it-

How do I test engine computer control for 1993 dodge intrepid 3.3L 40 pin to check diodes. like to see a chart or diagram.


This type of parasitic draw can be tricky to find.Hopefully this will help you. I am a master tech and the electronics specialist where I work.This is how i would approach this problem.
Turn the car and ignition off.put your meter on current setting 10amps DC..and .put it in SERIES with negative ground cable. polarity of the meter leads does not really matter like with measuring voltage.The meter should read about 200ma of current with the car shut off.,once the interior lights go out...before that it will show a couple amps..Then leave the meter hooked up and about 20 minutes later,the body control module puts the car in "sleep" mode and current should be around 2ma.. (.002amps) This is normal PCM current drain. If the current is higher than this,pull fuses out one at a time until the drain goes away.this is the problem damaged circuit. Most meters have an auto shutoff function for the display to save battery life. if the meter shuts off before the 20 minutes is up,,just turn it back on ,DO NOT disconnect the meter as the 20 minutes will have to start over.
Testing diodes is simple. with the meter on diode check,there should be a .7 volt drop one way and infinite the other.
A shorted diode will read 0 volt drop in both direction because it is shorted.
An open diode will read open in both directions.

Assuming the battery is fully charged, the connections from the battery red to starter motor & relay are tight, and black terminal from battery to engine block (or chassis) are tight, and cables &/or terminals are not corroded, and the battery electrolyte levels are not low to expose the battery lead plates, the symptoms you describe sounds like a main fuse panel issue. Some cars have two fuse panels; one beneath the driver or passenger console, another one beneath the hood in engine area. If fuses are OK, then not enough electrons are passing through when you turn the key, meaning something is acting as a resistor to prevent free flow of electrons (loose connections or corroded terminals or cables). When you pop open the caps off the battery, each cell holds 2 volts. If the lead plates are exposed, that cell will hold less than 2 volt. Replenish with distilled water or battery electrolyte (sold at some auto parts store, so call around instead of driving all over town). If you have a battery charger & digital voltage meter, the battery should read 12.6 to 13 volts for fully charge. If below this, touch black probe on voltage meter to negative side of battery, then dip red probe on each of battery cell's electrolyte. Write down the voltage reading of each cell, then hook up the battery charger let charge for half an hour or so until battery shows 12.6 or higher reading after unplugging the charger. With charger unplugged, take digital voltage meter and take 2nd voltage reading of each cell, dipping red probe into electrolyte while black probe touches negative side of battery. Write down voltage reading of each cell. Wait half an hour to 45 minutes, then take a 3rd voltage reading of each cell. If there's a drop in voltage reading on one cell from the 2nd time, this cell is not holding a charge and its draining power from the adjacent cells, resulting in eventually leaving a dead battery after it had been parked over the weekend. Replace the battery. This method of diagnosis to check battery condition is more accurate than a load test. I've seen batteries that will pass a load test, yet battery goes dead after the car (or semi truck or bus) had been parked for 2 or 3 days because the faulty cell had drained power from the adjacent cells next to it. In semi trucks & buses, when the battery goes dead, it continues to drain the power from other batteries that are hooked in parallel or series to other batteries.

Battery drained


disconnect the earth wire from the battery and place a multi meter in the circuit and read the current draw through the current (AMPs) section of the meter. That will tell you what is drawing current and how much.. Things to check include the glove box light is off, boot light is off. the radio amp is off when the ignition is off. When you have done that hook the multimeter across the battery after replacing the earth wire ( red lead to positive and black lead to negative) and start the engine hold RPM at around 1200 and read the voltage in the battery It should be 14.5 volts dc now set the multimeter to read ac and see if you have any voltage there IT should be 0 voltage . That will show that the alternator and rectifier diodes are ok. Check that the drive belt is in good condition and tensioned right.. You say 3 batteries in 13 months . How many have been brand new out of the battery shop type and how many are new to you from some place else. If they have not been new as off the shelf new then have a load test done on the battery as it may have an internal short

Does not start, battery ok. alternator and starter test out ok


The car battery has 6 cells, each cell holds 2 volts, and connected in series adds to 12 volts. Just like your flashlight, each battery hooked in series results in increased voltage. Its possible one cell is not holding a charge, which slowly drains power from adjacent cells. In battery series connection, if one cell won't hold a charge, electrons will flow to lowest cell voltage in attempt to equalize voltage. So when one cell drops to less than 2 volts, the electrons from other cells will flow to this cell to recharge and bring voltage up to equalize voltage level. To diagnose for dead cell in 6-cell car battery, remove the 6 caps to expose the electrolyte liquid AFTER you have recharged the battery for 20 minutes with 10-amp charger, or until "fully charged" indicator comes "on." With a digital voltage meter set to 5 volts DC reading, connect the negative black probe to negative side of battery and touch the liquid electrolyte with the red positive probe. The voltage meter will display the voltage reading on each cell as you move the red positive probe from one cell to another. Make a note of each voltage reading from each cell. Wait one hour or more, then take another reading of each cell. The cell that has the lowest reading is the one that's draining power from the adjacent cells. A normal battery will show no change in voltage level between the first and second reading an hour later. A defective battery will show a drop in voltage to indicate one or more cell is slowly draining power to gradually render the battery completely dead 36 hours later.

Battery drains while sitting


Hi Anonymous, perform the following tests:
1. Fill acid type batteries to proper levels.
2. Charge battery overnight at 1-2 amps you need 12.5 volts or better after charging.
3. Hook up battery positive cable, then with your multimeter on the milliamp scale connect one lead to the negative battery post and the other lead to the ground cable. Meter should read 3 milliamps or less, 10 milliamps with a radio, 15 milliamps with radio and CB. If your meter reads higher you need to isolate the circuit by pulling fuses and circuit breakers one at a time and observe meter for drop in aprerage then get out your test light and track down the short in that circuit.
3. Make sure all connections are clean and tight especially the negative cable at "BOTH" ends.
4. Hook up volt meter to battery and start engine, if meter falls below 9.5 v while cranking replace battery.
5. With engine running at 3600 RPM battery should read 14.3-14.7 volts if not continue tests.
6. Unplug voltage regulator from alternator at crankcase by front of primary cover.
7. To test voltage regulator go to: https://www.youtube.com/watch?v=F8EjV0IjW9Q
8. With ohm meter, one lead grounded, touch alternator pin meter should read infinity, if not replace stator.
9. With ohm meter, both leads touching alternator pins meter should read 0.1 to 0.2 ohms on 1989 and later models. 0.2 to 0.4 ohms 1988 and earlier models, if not replace stator.
10. With volt meter set on AC scale, both leads touching alternator pins meter should read
16 to 20 volts AC for every 1000 RPM'S 1989 and later and 19 to 26 volts AC for every 1000 RPMS. If not replace rotor.

Okay my boyfriend has a 1999 dodge intrepid with 172,000 miles on it. he bought a new battery but now the battery light is still on? do you know what the problem could be? also what could he do to get it...


if the battery light is on while running the charging system is not working.you can check
with a volt meter,setting meter to dc volts & connect meter leads to battery.reading should
be 13.2 - 14.5 volts if lower than this your only reading battery voltage.check single red wire to the alternator it should read battery volts 12v.if battery voltage is present than alternator is faulty,if no voltage reading you'll need to trace & repair the wiring
note; battery should be fully charge before testing

good luck

Your alternator should power everything when engine is running. Battery is only for start up. Test voltage with a multimeter when engine is running , should be 14V or more . Any less indicates low alternator output.

Electric problem on 2002 Jeep cherokee 6


I had a similar problem, Mine turned out to be a weak cell in the battery. Here is what I did to find it. First, check what postion is the dome light switch in when this problem happens?

Disconect the negitive battery terminal. connect a volt, ohm, amp, meter in series between the negative battery terminal, and the disconected negative battery cable. How much voltage is showing on the meter? open the door does the voltage go up, or does it drop off?
Close the door wait 30, 40 second voltage should start to decrease back down to 0. This is normal the dome light uses a module to control the dome light delay.
If the voltage does not drop down to zero with the door closed after a min. or 2, select the amp setting in your meter, read the amperage draw. This is what drains the battery, the higher the amperage reading the quicker the battery will drain.
With the meter still hooked up remove one fuse at a time, when the amperage drops off you have found the defective circuit.

My batterys dont charge after a long run or short i hasve to recharge them to start the car i have checked them with a batterys tester and they are ok but something is drainning them or not charging them...


Check voltage at battery before you start, then start & check voltage while running. Obviously your battery reading should start climbing to 13.5 - 14.5 VDC when engine running, otherwise alternator is defective, unless that car has an external voltage regulator on it. Make sure your alternator belt is in good shape & tight, and all connections at battery, & alternator are clean & in good shape. To find a battery drain when vehicle is shut off, use a 12vdc test light connected between positive connection & battery post. If the lights on, you have a drain, & start removing fuses to find the culprit, or remove all & start putting them back in until light comes on bright. Now you've isolated the circuit causing the draw. should give you an idea where to look. Remember your radio will have a constant small draw for memory function.
