In this video, I demonstrate how to troubleshoot an issue with the alternator in my 2001 Isuzu Rodeo. To learn how to replace the alternator in a second generation Rodeo, check out my replacement video by clicking the following link:

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.
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 videos on this channel, subscribed
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.
U can tell me please whats meaning g-sensor on isuzu demax its make Abs lamp on and error code num its c0276
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.
Please film whatever work you do on this vehicle, as a youngin with not very much mechanic knowledge, your videos help me so much with my rodeo
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.
