There is a fusible link in the connection between the alternator and the positive battery cable connector.

On the 1997 it is a 175 Amp Mega Fuse mounted on the outside of the high voltage fuse box located on the drivers's side in the engine compartment. After replacing the battery and the Alternator, it turned out to be a $4.99 fuse that was keeping the alternator current from reaching the battery.

The alternator cable bolts on to one end of the fuse, and the positive battery cable bolts on to the other end. You can test it inline without removing it by checking for continuity across the two bolts. An open circuit indicates that the fuse is blown and needs to be replaced.

If the fuse is blown (which means you have an open circuit), the battery light in the dash should be on.

The car will start normally if the battery has enough of a charge, but it will eventually die when the battery is too depleted to keep the car running, because the alternator can't take over if the current doesn't make it across the blown fuse.

If the battery is dead, it will start with a jump start, but it will die shortly after you remove the jumper cables for the same reason.

This is one of those problems that you might not think of right away, and it will drive you out of your mind. ALWAYS check this fuse before replacing a battery or an alternator on a mid to late '90s Model Thunderbird. You will save time, money, and you won't pull out your hair.

    after replacing alternator 3 times and the battery twice not to mention the many times had to have car towed....I really appreciate your information here! If only had been able to find your post a year ago. Thank you so much! Now...maybe you can tell me why my 1991 thunderbird suddenly will not shift out of 1st gear and goes 25 miles per hour. That would be great!

Voltage Regulator REMOVAL & INSTALLATION Electronic Regulator

  1. Remove the battery ground cable. On models with the regulator mounted behind the battery, it is necessary to remove the battery hold-down, and move the battery.
  2. Remove the regulator mounting screws.
  3. Disconnect the regulator from the wiring harness. To install:
  4. Mount the regulator to the regulator mounting plate. The radio suppression condenser mounts under one mounting screw; the ground lead under the other mounting screw. Tighten the mounting screws.
  5. If the battery was moved to gain access to the regulator, position the battery and install the hold-down. Connect the battery ground cable, and test the system for proper voltage regulation.
Integral Regulator
  1. Disconect the battery ground cable.
  2. Remove the alternator from the engine as described previously.
  3. Remove the four screws retaining the regulator to the alternator rear housing. Remove the regulator, with brush holder attached, from the alternator.

SOURCE: alternator not charging battery

You may need to have it tested to see if it's working the connections on the battery may not let the charge through or the battery itself may not take a charge if it's no good

1992 holden barina charging problem already replaced alternator but still slowly drains battery


It is not charging the battery because of several problems ---1 when connecting up the wires to the alternator was there a spark at the connection ---2 is the heavy wire on the alternator insulated from the body of the alternator--- is there a fuse in the charge circuit that is blown---4 is the light wires pushed fully home in the connection--- have you the correct alternator for the car ( internal or external voltage regulator)---5 is the drive belt in good condition and tight- If everything checks out then take it to an accredited auto electrician to have the alternator tested properly as new alternators ( out of the box new) can be faulty.

Battery keeps draining already put in a brand new alletantor and brattery still draining and battery lights comes on and truck won't start


You would have checked the charging system before replacing the alternator, so I will assume the charging system is good.
If the battery is being discharged overnight or over a few days, you would need to disconnect it and check every circuit on the truck to find the drain.

My battery dies i replaced a brand new alternator but still dosen't charge tomthe battery


The battery most likely has dead cells and not charging due to the alternator .The alternator is doing what it should, your battery just can't hold the charge the alternator is putting out. Go have the battery tested at a local auto zone or advance auto store. Free to check

2003 Chrysler Town & Country, put in new alternator, now have 2 lights on including battery and one looking like a pump. Radio won't work.


Hello
The reason the battery light is on is that the charging system voltage is below the battery voltage, this means the charging system is not working correctly, since you already replaced the Alternator for I assume the same problem, unless you got a defective rebuilt (which is poss if bought from Autozone or one of the other discount parts stores) the charging system problem is not the Alternator but lies elsewhere in the electrical system. Use a volt meter and check the voltage at the battery cables with the engine running at high idle (at least 1000 RPM) the voltage should be at least 13.4 to about 14.2 Volts DC. This is also most likely the cause of the light that is on that you say looks like a pump due to the low charging system voltage. As to the radio it is in theft lock, this happens anytime the battery is disconnected, you will need to enter the unique security code for your radio, if you are not the original owner this may be a problem, as the little card with the code and the instructions to enter it often gets misplaced. You will likely end up at the dealer who can access the Chrysler factory computer and retrieve the code, there may be a charge for this.

Ive already put a new altinater and a brand new battery in my cutlass. it will start when i give it a jump from another car but then as soon as i try to drive it it dies on me.. and ive also cleaned the...


New battery and new alternator,you are looking for a open fusable link,If all are good you maynot be looking at a charging system, start the vehicle at idle, leave it running turn on the light and use the battery gauge on the car and turn the lights step on the brakes (vehicle in park) does it stall then, If it does then you are looking at a charging system can you exhange the battery and can you get the alternator tested from an outside source or better yet uses a voltmeter and read the charging system the battery at charging will need to be 2 volts above battery

Battery light is on.wont hold a charge.starts after hooking up battery charger.thanks


If battery light is on while engine is running, then the charging system is bad. That is, you will need a new alternator. If the battery is a couple years old, you may have now stressed it a lot also. Expect it to show signs of failure too, quite soon if not already. First thing is to change out the alternator. Put the battery on charge for a while too. Then after new alternator, see if you have weak starting problems over next week or so.

Battery light keeps coming on. brand new battery in car and car keeps dieing


Hi:
The battery light means that your charging system isn't working, so you most likely have a bad alternator, or connection to the battery.
You can test your alternator with a volt meter.
First,get your battery 100% charged up. It should read about 12.6 volts.
Next, start your car, and check the voltage across the battery. It should be at least 14 volts. If not, you are not charging your battery.
Most auto parts stores will check out your battery or alternator for free, if you stop by and don't own or can borrow a volt meter.

Replacing alternator in 2004 escape


Have the whole battery/charging sytem tested. If it has an external voltage regulator or a bad battery, these things can kill a perfectly good alternator.
