Hey Matt, thanks for the troubleshooting tips on the Isuzu alternator. Helped me to know that my Troopers alternator was the real problem. Had the same symptoms, dimming headlights and dash panel. Again, thanks!

Great video Matt. Just inherited an old Jackaroo and am hunting an alternator issue. This has really useful information for an old novice fart like me. 🍻

Man, that is awesome! So glad you found my video, and it is fantastic to hear that you were able to repair your issue! It is SO frustrating when you feel like you can't trust professionals to do a good job of diagnosing and repairing your vehicle. Congratulations for taking matters into your own hands and getting it done!
Thanks for watching!

Did you replace the whole wire? And if so did it lead back to the fuse box?

[@richardtrowell8812]

@@xIRAIx The wire should be replaced. The corrosion works it's way back into the wire past where you can see. How far back is difficult to determine. If repaired could not be sure how long it would last or if all the problems would be fixed. To remove corrosion can use water with baking soda mix and put wire in solution. Old mechanics trick.

[@lloydbrothers3315]

Thank you so much for this. This is exactly my problem. I actually had 3 alternators put in. Watched this video and saw a corroded wire. These assholes at the shop were too damn lazy to fix this obvious problem. Ill be attempting to replace this wire myself. Thank you for sharing your experience. You probably saved me several hundreds of dollars and more wasted time.

Thanks! Same vintage same issue on my ride recently. The wire that runs from the back of the alternator is the thinner one that comes out of the same wire loom to the forward part of the fuse box.

Very very helpful thank you!

Another way to troubleshoot is to use a multimeter. an electrical system with a good alternator should read about 14v while the engine is running. If the alternator is not producing enough power then you'll read just the 12v battery. That's how I figured out my alternator was going on my 98 rodeo.

U can tell me please whats meaning g-sensor on isuzu demax its make Abs lamp on and error code num its c0276

[@tomquinn1192]

Almost all these Isuzus used as daily drivers need their alternators replaced between years 18 and 20. Next comes the starter motor. You can't ask for more life than that from electrical parts in daily use.
