Question about Isuzu Trooper

1 Answer

I either have an ECM problem or an alternator problem. How do I tell the difference. The battery runs down as I drive and the dash lights come on as the battery runs down. The battery is good. 1994 Isuzu Trooper

If you have a light on or your gauge says it's not charging, replace the alternator. Obviously, it isn't charging.

How do i get my car running again it broke down i got a jump made it home and next day wont start no dash lights radio it doesnt do anything what is wrong ?


Give the battery a boost. If the car starts and stays running, chances are the alternator is ok. If the vehicle will not stay running, once boosted, there will be a charging system problem. Possible alternator. If the battery is more than 5 years old, it can also cause problems as the life expectancy of a battery is 5 yrs. Very doubtful you have a starter issue. I would bet on a battery or alternator/wiring issue

I have a 2001 rodeo Isuzu the battery gets drained loses speedometer and ac stops blowing then reduced power light comes on.what could be the problem?


For starters, it sounds like your battery can't produce enough amperage. Have it tested and replace if needed. Then see if things are better.

Thinhking its the ecm


The ecm does not control the dashboard lights. I would start by checking battery, alternator and starter connections. Also, Gm uses aluminum wire and to check for white corrosion on ends of heavy gage cable.

Check gauge/low voltage


May or may not throw a code, have you had the alternator checked, this sounds like a bad alternator and also you charged the batteries but have them tested also, this sounds like an alternator problem.

Check gauge light comes on and voltmeter shows low voltage


Not if your alternator is faulty.
Check the battery voltage first, that will prove alternator.

2006 Impala Battery drains while car is running. Battery has been tested, alternator has been replaced. Connections to battery, alternator, aux power have been checked. Happens intermittently, sometimes...


drive belt tension
have the voltage regulator checked /replaced
if it is faulty the battery will drain as it is running all of the electronics without help from a alternator
AS the ecm draws a lot of current, a battery not charging will not last long
most modern cars run about 85% of the alternator with the rest for charging the battery
if the voltage regulator is part of the ECM, replace the ecm unit

I had a routine tire rotation and car alignment on yesterday. As I drove my car later in the evening, the vsc/ecm dash light came on, followed by the brake and battery light, radio and dash lamp lights...


Sounds like you lost the charge from the alternator.
When the alternator quits charging your battery light comes on and your car will run on battery power only...and only for a short time.
As the battery gets its stored energy used up...everything that is electrical will get slow or dim.

I'd check your alternator for proper operation and its drive belt...

Hope this helps...

No not the computer or wiring, when the battery goes out the alternator has to work harder. With a weak battery the alternator produces a magnetic flux the flux need to be disapated. Only a good battery can do that. All you bulbs took on at least 15vlts and are rated for 12(it can withstand 16vlts) the 2 lights on the dash any shop can do that or dealer

Your alternator has to produce at least 13.1 volts to recharge the battery. If less is produced then possible causes are alternator, wiring, fuse, drive belt. Your ABS and VSC modules will self protect and shut down when low voltage is detected. Repair the charging problem and the warning lights will be sorted too.
