Hi,all the alternators job is,is to charge the battery,so the alternator has nothing to do with it not starting.now if your battery keeps draining down and you have to recharge it every couple of days,then it would be the alternator that was bad.but if you have a fully charged battery and it still wont start, its another problem! does it turn over and try to start but not start?? or when you turn the key over does it just go click-click-click?? or does it just not make any noise at all when you turn the key over?? it makes a big diffrence which of the three its doing,let me know which one its doing, also you can take your battery to auto-zone and they will load test to see if its holding a charge ok.....just let me know.......yz-maniac.

    It does not try to turn over, nor does it click, click, click. It merely makes one hollow metallic sounding click that I can hear at both the starter module in the engine fuse box and at the starter. Prior to the Trooper quitting completely, the day before it sounded as if it were dragging when it started like the battery was low. I have had the battery tested and it is in perfect operating condition under a load. I also transferred my truck battery to the Isuzu but it would still not turn over. You haven't any idea how grateful I am for your response. When I mentioned the Isuzu dragging the day before the breakdown, it took place at KU med center where my wife is undergoing treatment for a life-threatening illness. I am not in a position to afford the 400-500 dollar quotes I've received from mechanics in our area to repair the vehicle and must take this task on myself. I am not by any means a mechanic but I'm not exactly a dummy when it comes to making do. I suspect the starter has locked-up but after crawling under this thing I can see it will be an immense task to remove and replace this thing under "shade tree" conditions. However, my ole' 96 Ford truck is not up to making the repeated trips to KC necessary to see to my spouse's well-being and I must get this Trooper fixed. It's bad enough that a new starter is $147 when every nickel counts right now. So, thank you so much for your helpful and kind response in this trying time of woe. May you be blessed. Earnestly, Rocky Griffith

    hello again lisagriffith,I'm sorry to hear about your wife's illness( i will pray that all goes well and she will have a quick recovery) yes it sounds like it is the starter itself , you might try one last thing that i have done in years past to buy a little more time, which may or may not work? take a wrench or hammer and tap on the starter housing and see if that frees it up( worth a shot,) i had a car that i did that on and it lasted another year before the starter died completely, I guess the trany is an automatic?( if it was a standard trany,you could park on an incline and just bump start with key on and putting in second gear and popping the clutch...) and i wish i was near you as well because under your circumstances i would help install your starter free of charge.may god bless you, and bless and heal your wife. sincerely,Danny.

Isuzu trooper 2002 it started shut down started then it shut off .Now i try to start it and nothing no buzz no clicking nothing,the battery is fully charged. i just bought it. can some one please help


Try disconnecting a battery cable. Reconnect 5 min later. This resets the ECM. These vehicles are a real continuing problem when they get old. I had a 1990 Trooper II and finally junked it last year.

You say the alternator tested good, on the car or off ?
There are two fuses from the alternator to the key switch, a 7.5 amp and a 15 amp. There is also an 80 amp fuse from the alternator to the battery.
I would check these fuses and the connections at the alternator, plus the ground between the engine and the frame.

Hello and welcome to FixYa!


If the battery light is on, I strongly suggest that you have the battery charged. It can be an indication of a weak battery or a faulty alternator. If the battery light still on after charging then the problem will surely be on the alternator itself. If that's the case the alternator should be replaced to resolve the problem.


If the battery won't hold charge even on a new alternator then the problem will be on the battery itself. It surely is in the end of it's service life and replacement will be necessary.


You may try to reset it to by removing the positive battery connector, letting it sit for at least 5mins. then reconnect it again. This will reset the system and can get the battery light off.


Hope this helps and thank you for using FixYa! Have a good one!

I replaced the battery in January for my Isuzu


In today vehicle there are many electronic device that still draw power from the battery.

Example:
Car radio memory on station pre-set
Car radio clock
Computer/ECU to save driving parameters
Car alarm + sensors
Power seat menory

To prevent problem,I will start the engine for 5 minutes once a week.

If are in an enclose area and has access to a power outlet then it's a good idea to connect a float battery charger to keep the battery is optimal condition.

Here is a sample of float charger / battery tender.

It's on sale for $7.99 now or you can but better quality one at your local auto part store for $30+

Link to Harbor Freight page HERE

It's a good idea to check for worn belt and weak alternator.

A belt with 60,000 or 5 years should be replace.

Check the voltage at the battery terminal after the engine is warm up for 5 minutes. The voltage should be above 13.8V

Auto supply store may provide more in-depth battery and alternator testing for free.

Please email me if you have any question.

ALTERNATOR REPLACED WORKING OK NOW TIMING BELT PETROL AND BATTERY WARNING LIGHTS ON WHEN ENGINE RUNNING AND A/CON NOT WORKING


If your battery warning light is on, then your alternator is NOT working okay. Rather, maybe the alternator DOES work, but the battery light can also come on if your battery won't charge.

Put a voltmeter to the battery terminals when the engine is running and rev the engine to a medium idle. Battery charging, (engine running) it should be about 13.5-14.5 volts. Engine off fully charged battery voltage should be 12.6 volts.

Quick test-engine running, disconnect the positive battery terminal from the battery- if the engine dies, there is still an alternator problem.

Hope this helps.
