It is possible for a altenator to go like that , how ever it ould be the battery has failed as well. the best way to diagnose a charging or electrial issue is with the use of a simple multimeter. set the multimeter to the 20v dc scale with no engine running put the red probe to the positive of the battery and the black to the negative terminal the multimeter should read some where over 12v consider the car isn't running so the altenator at this stage is doing nothing. start the vehicle in park or neutral with hand brake on and peform the same procedure. ideal voltage with engine running would be 13.6 to 14.5 with no head lights on . this is a very simple test to establish if the altenator is in fact at the cause of the problem, if the altenator is operating in that range it is fair to say it is working fine. if the voltage is reading over and high 15v the voltage regulator has packed it in and now the battery is at risk of being cooked from over charging, there are a lot more complexed tests that can be peformed but this should get the answer of whats going on. hope you find this helpful.

SOURCE: Key will not turn to start vehicle.

Try pushing in the key while turning the wheel either way. And jiggling it. This happens because the steering locks for the car's protection. If we park it with the wheels turned, it locks in that position. If that does not work, you may have to call a good mechanic to help you.

SOURCE: Battery is 11 months old,

This is a typical starter problem. If it were a battery you would have been able to start the car when it was jumped.

SOURCE: I purchased an isuzu trooper model 1999, manual

No, but what I would do is buy a used computer or borrow one from somebody to see if that is the problem before you buy one from the dealer. they are expensive, used about $100. A couple of things would cause the car to stop, one, dead battery, bad alternator, but the light should have come on, the battery light would have come on too. But the car will not run without them. The injectors, I don't know that much about diesels, but, I do have 3 Isuzu's.

Ignition clicks but doesn't turn over


If you just replaced the battery then my guess is that you have a bad alternator. Your fresh battery could hold the charge for a couple days without being charged but now it's dead. Try charging the battery (via jumper cables or a battery charger). If the car starts up after the charge then you probably need a new alternator. You can verify this by checking the voltage across the battery after you start the car. The voltage should be more than 13.5 volts, if it's any less than the alternator isn't charging the battery. Good luck!

Vehicle was parked and not started for 2 months.


Hi, there will be diodes in the generator that are letting the power from the battery drain away through the parked times when not in use. to prove it charge the battery- then disconnect the negative terminal on the battery, connect 24 hours later and see if the battery as kept it charge, if so - fit new alternator, good luck.

Battery died because i left the car lights on in the morning when i parked the car and went in to my work office. is the battery fully dead? what needs to be done? will jumper cables solve the problem?


Hello. The battery will recharge. Just use jumper cables, and a friend's car to give your car a jump. Then drive it around for at least thirty minutes before shutting it off again. No permanent damage done!

Starting problem, battery? alternator??


Unless you have good jumper cables it would start easy since I didn't get in on the begining of this I will assume you have a bad connection tothe starer or a bad starter if it drags.

Its sure sounds like the alternator to me. If you have a battery charger charge the batteryup for an hour or so start the van and if you have a volt meeter put it on th e battery and see what it reads should be around 13.6 volts make sure everything is off at this time heater radio ect if that reads around 13. volts now turn on the light s radio heater and 4 way flashers and see if the voltage starts to drop if it drops below 13. volts the alternator is bad also if the battery is over 4 years old replace it.If all elese fails take it to a well know repair shop

Back fire while driveing


check for vacuum leaks at your throttle body, intake manifold gaskets and vacuum line, or you could possibly have a sticking valve. if I am understanding you rite the truck sat for 2 years. also check the wiring to your sensors as for a rodent may have chewed some insulation off, this happened to my sons car.
