What happens if your alternator doesn't work?

It will seem like it is your battery. It may start at first but eventually will die and you will attempt to use jumper cables to restart it but as soon as you disconnect the cables it will die again. The only fix is to replace the alternator , when i replaced the one in my truck i did it myself for about 140.00 If this helped please recommend :>)


Car wont jump start?

Possibly the connection at the battery. Corrosion between the cable and the battery. The jumper cables are only connected to the cable and nothing is getting through from the battery in the car. Sure you have connection at both ends of the cables. It may not be the battery, starter may be bad or if the cables are badly corroded, the corrosion can work down the cable inside of the insulation and that will make them not work.

Only if the cables are connected improperly.


Why will 1995 Honda Civic DX only start when jumped with jumper cables- it won't start with a jumpstart pack that is fully charged- Ran for 30 min to charge and no start- Alternator or ignition switch?

If it were the ignition switch, the vehicle would not start even with a jump. The battery is either not holding a charge or the alternator is not providing the charge to the battery. You can have the battery and the alternator checked (usually free of charge) at an auto parts store,


Sears Tractor runs only with jumper cables attached to a good battery After disconnecting the cables the tractor engins within seconds It's a 17 Hp Kohler engin on a Sears 42 mower tractor?

If the tractor had a battery in it when you were jumping it, there is a chance that the battery is bad. Try unhooking the tractors battery and trying again. Hook your jumper cables to the battery cables themselves without being attached to the battery. If it runs then just replace the battery. A battery with a short in it will keep the mower from charging and could cause it to die. If there was no battery in the tractor when you were jumping it, then the tractor is not charging and will have to be diagnosed as to what the problem is.


What happens wen you get eletricuted by a car battery?

You will not get electricuted by a car battery. It has only 12 volts and that will not cause you any harm. The sparks that come from connecting the battery or connnecting jumper cables are just electrical current being transferred.

What would cause a 1998 Mercury Villager to start only with a jump?

Dead battery? Battery cables in need of cleaning or replacement?


When you turn the key it goes as fare as it can but only makes the lights come on?

Means your battery is very weak. Only strong enough to light up the dash but not enough to start the engine. Get someone to jump your car with jumper cables. Make sure the person revs their engine while the batteries are connected to each other. Have them rev their engine for at least five minutes before trying to start your car. Once you start your care you need to drive to a place where they can test your battery and change it if needed. DO NOT TURN OFF YOUR CAR AFTER YOU GET IT STARTED BECAUSE IT MIGHT NOT RESTART !


What would cause a clicking noise only when lights are on and engine does not start?

Weak battery? Loose or corroded battery cables? Starter solenoid?


What is wrong if after hooking up jumper cables wrong the car will start but will not idle and will only run if the gas pedal is held down?

You blew the voltage regulator. Depending on the model, it is either a separate component or located inside of your alternator. Based on your problem, I would guess you need a new alternator. Replace it and your car will be fine.
