    The battery does die after a short while of driving the 14.1 Volt was a test done with the alternator out of the car.

If the drive belt is correctly fitted and tensioned the alternator should be charging....have it checked and, if necessary, replaced
I am assuming that all the charging components, such as the regulator, are integrated in the unit.
Also, have the specific gravity of the cells in your battery checked for health/condition...might be the battery is not holding a charge very well, could be a dead cell.

Testimonial: "i have had all that checked and the alternator in the car is not putting out any more volts than the battery has. the bench test was 14.1"

    the voltage sounds fine, the nominal charge of a battery is, as you know 12v and that should be the minimum value. I am a little confused so I hope you do not mind me enquiring further to clarify the situation for my benefit.
    You say the alternator is not charging, is the battery running down after a very short while please?
    You have 14.1 volts at the battery with the engine switched off? or running please?
    You have had the alternator checked with the result that what was discovered please?

Check the Bat. terminal at back of alternator with engine running. If you have more than battery voltage (14.1 for example) at terminal, but not at battery itself, then you need to check wiring from battery terminal at alt. to pos. battery term for resistance. You could have a corroded connection at the positive battery terminal (smaller gauge wire), not the heavy gauge cable.

    I f I have this right at last the alternator is tested and is functional.
    I presume you are charging the battery on a charger?
    There must be a break in the charging circuit somewhere if the battery is holding a charge and the alternator is fully functional..
    The charging circuit is about as simple a circuit as you will find so tracking down the issue should not stump you.
    Using a multimeter start checking the circuit or get a competent auto electrician to test for you.

My 1996 s10 blazer with a 4.3L was idleing warming up and id died and hasnt st arted since. ive got no fuel prtessure no spark no voltage through the ECM fuse and no cluster lights. Help


You talking ecm bat fuse 20 amp? Voltage to that fuse is hot all the time. It comes from fusible link. Make sure battery has a full charge and connections all good. Then check fusible links, one way to check fusible links, use a test light and check voltage on both sides. I usually follow battery + circuits to find fusible links.

The battery is new the alternator is good but the battery is dying


Your alternator has a fusible link coming from the battery to the alternator,fuse probably is blown.The link is in a box next to the battery.

Alternator checks out good and battery checks out good but alternator does not charge battery is there somethin g else I can check


You have to make sure that you are getting power to the alternator. It could be something as simple as a blown fuse in the power distribution center.

2000 dodge ram check guage light comes on. have a new battery and new alternator. also blew a 50 amp fuse.


Hi Les, I;m glad to help. There is an fusible link that runs off the battery cable pull on it and see if it comes apart, if it does replace it and see if everything is working properly. Hope this helps and have an awesome day Les.

Where do i trace my orange/blue wire to from alternator? i have new alternator and batteries, but won't charge. will charge if i jump orange/blue to positive post. Any good suggestions? Thanks Phil


The orange/light blue wire is connected to the red (positive) wire from the battery, through a fusible link (or two links depending on engine size) to pin #3 of the voltage regulator at the alternator. The fusible link will be in the harness so you may have to disassemble the harness. The fusible link is probably blown. This was probably caused by the defective alternator/regulator assembly.

According to my diagram, it appears to go from the red batt wire to a gray 12 gauge fusible link, into a brown 18 gauge link, then turns into the orange/light blue wire and to the alternator.

(A fusible link is a piece of wire that acts like a fuse and will burn out, opening the circuit when amperage above its rating. This protects the circuit and lessens the chance of fire).

Good luck, please ask if you need more info.

Battery light stays on - not charging. battery & alternator good.


latifrashed, Look for an inline fuse coming off the alternator wires. Ford sometimes uses a 20 amp fuse located under a cover on the firewall marked engine main fuse. Check the fuse and if blown then this should solve your problem. If there are fusible links involved then these will have to be checked as well. Good luck with this.

New battery won't charge, alt. good from bone yard, is there a voltage regulater on this car?


The VR is integral to the alternator. Check the fusible link and the 10 amp fuse in the battery fuse box.

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.

No charge to battery


IN ORDER:
Check the 120amp Alternator Fusible link#13 (for 2002 model) located in the fusible link block. (Note: a fusible link is a properly sized piece of wire that is designed to provide major protection when a short occurs) as regular fuses provide minor issue protection.

Check the 5amp ALT-S fuse as this directly affects charging.

Lastly check the 10amp IG2 fuse.

You may find that you have now have a spare alternator (your orginal that was ok) OR You can always sell it on ebay or craigslist.

No charge to battery


the starting /charging system is interrelated ....check amp draw of starter...be sure ALL grounds on engine alternator starter battery are clean and tight...also you could have a parasitic electrical leak...disconn neg side to battery and put test light in line..should be faint light for radio and computer..nothing more..if it burns bright you have something drawing power when system is off..pull fuses one at a time to discover where ....good luck
