I recently replaced the alternator on a 2007 3.0L diesel jeep and the red battery light came on only after the new one was installed. It is charging well and has 190A output. Please help ASAP!

My 1992 jeep cherokee laredo wont charge


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.

Does a 1996 jeep have a generator and an alternator? The light came on as GEN.


usually the generator and alternator are in the same device, older vehicles may have the alternator circuit seperately installed somwhere else.

The Gen lamp indicates that the battery is no longer getting a charge. or there will be a red battery sign lamp.

at this time of year on older vehicles it maybe that your battery needs replacement.
it is better to get a garage to check your battery status, as you dont want to find out that you need a new battery after buying an new alternator then you end up buying both.

I hope this was useful.

I just bought my son a 1996 Jeep Grand Cherokee Laredo. The battery and alternator were both recently replaced by the previous owner. He drove the car 2 days no problem. Today the battery was draining as...


the alternator failed this is usually a chrylser and jeep dodge isue the bearing fails and the alternator quits charging the if the light comes on its usually alternator but on some jeeps the light dosent come on because it reads that it is charging

the other thing that it could be is the battery shot on ya the only thing you can do to see if its a good battery do a battery acid test

I have a 95 jeep cherokee laredo. The battery suddenly started dying. We got a new battery. Still died. Installed new alternater and charged battery. The jeep ran for about an hour and died again. What's...


First: Are your Battery Cables (inside) and Battery Post nice and shiney? It is amazing how corroded/oxidized cables and post will kill a battery. Get then bright and shiney.
To test the Alternator. Start the Vehicle. You can Jump it if you have to. With the Engine running, disconnect the Negative Cable from the Battery. If the Engine dies, it is a bad alternator.
Was the "new" Alternator new or remanufactured?
Was it the correct alternator inespecially 'amps' for your particular vehicle?
Take the "new" alternator off and have it tested at auto parts store where you bought it.
Any remanufactured alternator may pass the factory inspection but will fail at the auto parts store. Just because it came out of a new box, and looks new, doesn't mean it works new.
Always when buying and part with a "motor" attached to it from an autoparts store, insist that the new one gets bench tested.
If this does not fix the problem:
Are your belts slipping? Worm out, loose or slipping belts will not turn the alternator pulley correctly and draw the battery dead.
Inspect the Red Positive Wire coming off the Alternator back to the battery. Look for any burnt, melted, or shorted areas.
The Battery Starts the vehicle. The Alternator runs the engine and trickle charges the battery.
Let me know if this helped, or if you have addtional information or questions. Feel free to contact me at FixYa.com!

Generator light on 1996 jeep cherokee. what does


First clean the battery terminals & their connection to the battery. Check to see if the alternator belt is tight. Once started, connect an amp. meter to thebattery terminals. Black to black, red to red. If the reading is over 13.2, alternator is charging. If it is not, change the alternator. If it is over 13.2, you may need a new battery. Have a load test done at any reputable automotive store. Hope this helps & if it does please do the right thing & recommend this advice. Thanks

Charging problem on 1996 Dodge Ram 3500 Cummins Turbo Diesel


I had the same problem on a 94 dodge with the cummins. It seems the crank sensor that reads from a notch on the harmonic balancer was the problem Without this sensor reading that the engine is running the alternator wont charge. Possibly the same problem with yours
