Electrical problem after changing alternator

I had forgotten to disconnect the battery cable before taking out the old alternator. I accidentally arced across some metal, then removed cable. Now after the new one is in and I started the car, I have no warning lights on the dash, no tach,wipers, power windows, blower motors, and interior lights. I still have radio and headlights though. I've checked every fuse I could, including the main fuses, with a tester and none were bad. The car does stay running, but when I put my volt meter on the alternator it reads less than 1 volt. The altrnator I was replacing had just been installed 4 days ago, when my warning light on the dash came on again. When I tested the old one(4 days old) before removing, the voltage was fluctuating from less than 1 volt, up to about 11.5 volts, but never holding at the high end for more than a few seconds. When I told the guys at the parts store this, they just gave me a replacement. What could be wrong?

    Did you take the fuses out of the fuse block to test them?

  • rtgeurts Jul 09, 2010

    Yes I did.

  • rtgeurts Jul 10, 2010

    Problem is solved. The only fuse that wasn't tested was the 100 amp battery fuse, because I couldn't just pull that one out without pulling apart the fusebox it was in and removing some screws. I also assumed that the car would not run if that one had blown. Wrong. Less than a $4.00 fix.

SOURCE: Going through alternators

Hi there, I am a girl (i.e. not car savvy), but I have a 1998 Altima as well, and the first time (4 months ago) I noticed the brake and battery lights on simultaneously, I took it to a Nissan service shop. Everything seemed fine until about a month ago when the symptoms returned. I ignored the problem for 3 days and the car just stopped running, period. Took it back to the shop, figured out it was a fauly alternator, got it sorted, no problem. Today (1 month after replacement), I see the same bloody problem, and I'm taking it back to the shop in the morning. I am wondering... is it the alternator, or something connected to the alternator that is malfunctioning? The 2 alternators put in were "rebuilt" since they didn't have genuine Nissan alternators available. I really hope the dealers aren't taking me for a merry ride.

The two problems are more than likely related. Solve the voltage problem and the blower problem will disappear. Check for a slipping belt or an intermittent internal problem with the alternator. There could also be a wiring issue.

Disconnect (-) ground cable from battery and replace alternator. Reinstall the (-) ground cable after installing the alternator to avoid arcing and possible damage to the new alternator. Always wear safety glasses when working with car batteries. An explosion and acid burn hazard exist.

Engine electrical alternator


1. Disconnect positive cable from battery (or sparks may fly when you are disconnecting alternator wires).
2. Loosen and remove alternator belt (use the appropriate wrench, socket and/or ratchet to push/pull the drive belt tensioner to take spring tension off the belt)

3. Disconnect wiring harness from alternator
4. Unbolt alternator from bracket
5. Do steps in reverse order to install new alternator (inspect belt carefully for cracks, replace if necessary)
NOTE: If you want to test your charging system, buy or borrow a simple VOM (Volt-Ohm meter), and check the voltage across the battery terminals with the car running. Voltage should be between 13.5 and 14.5 volts if alternator is working properly. Make sure battery terminals and cables are clean and connected tight. Charging system may not function properly if cables are corroded or loose.

I have a 1990 Chrysler Lebaron Convertable, 3.0l V6 with 64k miles. This past week the "Check Engine" light came on and then the lights started to go dim. Finally the car died. Classic alternator...


Could be just a need to reset the "check engine light", normally this is accomplished when the battery is disconnected for 15 minutes...If your Lebaron is now running smoothly, have the alternator battery tested for free at most auto parts stores for peace of mind. Auto Zone can also read the check engine light code for free. Tight belt, good tensioner pulley, good alternator, you should be in business. Most likely no harm done when the arc occurred.

How to change altonator on sedona 3.0


Disconnect battery negative terminal. ( make sure you know your stereo code if it has one before doing this)
Disconnect the alternator wiring.
Remove the alternator drive belt
Remove the alternator locating bolts.
Take out alternator.
Reverse instructions for refit.
Once refit is complete, check charging rate across the battery terminals. It should go up to 14 volts with the engine at 2,000 revs.
Good luck.

1998 olds bravada would not start. Tightend the battery cables and it started. Now the battery light is on and the volts are down to 9. The car will start but scared that it might cut off of me. Is it...


If tightening the battery cables helped but did not fix, you may need to take the cables off and clean all the connections. If there is enough corrosion, it causes enough resistance to lower the voltage. Take the connections off and clean the cable and battery with a wire brush. Apply a coat of grease and put it back together. If this battery is a post type there are cleaning tools that have a post cleaner and a brush the will clean the inside of the cable clamp. You can find there at most any place that sells car batteries. They are cheap and well worth having. If it is a bolt on connection you should be able to clean with a regular wire brush. Clean until all the metal is shinny. There are also some spray cleaners available. When you disconnect the battery, always disconnect the positive post first. This ensures that you don't accidentally touch the cables and cause a short. Reverse the procedure when you reconnect the cables. If this doesn't help, have the battery checked. Good luck.


Thanks for using FixYa.

Hi, is there any special things I need to know, short cuts or tricks in a removal and replacement of my battery in a 2000 ford mustang with a V6? thanks, Sarah

1. Ensure you are using the correct spec replacement battery.

2. In many vehicles the radios and sound systems will cease to function if the battery is disconnected and require the radio code (supplied with and unique to the vehicle) to be punched in to activate the unit once power is restored.
I am not sure if the 2000 Mustang has this feature.

Make sure you have turned off all electrical functions on the car and remove the key from the ignition.

3. Batteries are dangerous as they emit explosive gasses which can ignite easily with one spark.
Do not change the battery immediately after running the car. Open the bonnet and allow air to circulate for a while before changing. Wear protective eye wear and clothing when working with the battery and remove metal objects such as rings ,watch bands, bracelets etc. as these could accidentally touch a battery terminal and cause a spark. (Be careful as I have personally seen a car battery explode when gas emissions have ignited with a spark).

4. Disconnect the cable from the negative ( - ) terminal first. Using a spanner, loosen the nut on the cable end and gently remove the cable from the battery terminal. You may need to move it around a little on the terminal before it slides up and free. Disconnect the cable from the positive (+) terminal second by loosening the nut and gently removing the cable. Move the cables out of the way and place a plastic cover wrapping over both cable ends so they do not accidentally contact an exposed battery terminal.

To eliminate risk, wrap some plastic electrical tape around the old battery's terminals before removing it. This ensures no accidental contact with metal parts of the car when moving the battery. The new battery should have a plastic protection cap over each terminal. Do not remove these until the new battery is secured and you are ready to re-connect the cables.

5. The battery clamping system will need to be released to remove the battery.

6. Check the metal cable terminals for corrosion (the presence of white ashy material). They will need to be cleaned up before connection to the new battery to ensure good contact.

7. Install the new battery on the battery platform ensuring it is firmly and properly seated and clamped with the clamping system. Ensure it is properly secured before re-connecting the cables.

8. Connect the positive cables to the positive (+) battery terminal first and then the negative (-) second. (The reverse of removal). Do not overtighten the nuts on the cables when clamping them to the battery terminals.

9. I usually run a very light and thin smear of petroleum jelly over the metal cable ends and top of the battery terminal once everything is clean and connected up. Now replace the protector cover (if fitted to your vehicle)) over the positive cable end and you are done .

10. If your car radio is coded, disconnecting the battery will clear the code on the radio so ensure you have the code available to reset the car radio after the battery is reconnected.
