At this point, no one can answer that. What you need to do is make sure that the battery is fully charged. If not have it charged. Make sure that the alternator drive belt is sufficiently tight and in good condition.Make sure both lead connectors are clean and properly tightened (not just on outside, but where they contact battery posts) Make sure that all connections at the other ends of the cables are likewise clean and tight.To do a "quick test" on alternator, With vehicle running, place a volt meter across the battery terminals. With no accessories on, charging volts should be between 13.5 and 14.0v. Turn on all electrical accessories, including high beams. Voltage should not drop below 12.5v.. If it does then you likely need to change alternator.

Why wont my Jeep Grand Cherokee Limited start?


Sounds like you have a bad alternator. Not recirculating juice back to the battery.

I have a 2004 jeep grand cherokee. on saturday night i jumped it off, and while connecting the jumper cables there was a large spark, now the vehicle idles roughly and sometimes cuts of,f can you help


Sounds like you shorted the diode in the alternator. Drive to nearest parts store and let them test it if possible, recommend fully charging the battery before atempting this and dont try to do it at night because the headlights will kill the battery quickly. Another option is to remove the alternator and carry it to the parts store and have it tested. I'm assuming the vehicle is already out of warrantee but if not have it towed to the dealership to be checked out. I'm fairly sure its an alternator problem.

98 cherokee starts for 2 seconds and shuts off.


Sounds like a serious short and or blown fuse. Check battery voltage. Move on to underhood fuse block. Check all fuses. Move on to cabin fuse block. Check all fuses. Check fuel cut-off switch. Reset switch. If you still have the problem and the battery is good than you have a short in your starter, alternator , or fuel pump. I won't go into lighting cause I figure you can tell a bad bulb from a good one. If your battery voltage is 12v + with the engine off your ok. If you can start the engine, check the voltage at the battery again, it should now be around 14v. If not , go to the positive terminal on your alternator and check the voltage there. If you read 14+ at the alternator and not at the battery , then the wiring in that circuit needs to be changed. A quick alternator test is to disconnect the negative terminal of your battery while the engine is running. If the car dies then your alt is bad. If you read lower than 12v on your battery. disconnect it, add water unless its maintenance free., charge it on a charger or preferably get a new one. Go and feel your starter for excessive heat. A short will also heat up your negative battery terminal

Headlights cutting out on my ford thunderbird


Your alternator may be on its way out. The alternator keeps the battery charged while driving and if the battery looses charge extra lights on the vehicle are usually the first to go.
A rarer possibility is that there is a wire that is rotted. I would get your alternator tested first.

Cuts off while driving sometimes


Sounds like you either have a fuel filter that needs changing, a pump beginning to go bad, or a crank sensor starting to go away... All common problems. Though I recommend you check these items, you also need to do a code scan and complete diagnosis before changing anything...Without verifying the exact cause, you can spend a lot of unnecessary $ before you hit on the solution!!
