    2006 charging at 15.8V

    It had some Dekas in it when I got it, and I put oreilly batteries back in it. No AGM since I’ve owned it but who knows before

    Alternator fixed the issue. Must have had a bad regulator in the other. This is why I don’t trust shops when they tell me something is wrong or something is fine.

    2006 charging at 15.8V

    Just ordered a 145a alternator. Was $70 cheaper than the 105a so I figured what the hell. Will post whenever I get it installed

    2006 charging at 15.8V

    The wires going to the alternator look quite small, I’ll price out what each alternator will be and go from there. Might get a slight upgrade if it’s around the same price. I think the part number I’m looking for is 94011605, it’s the o ring for the metal pipe with a 90° bend that plugs into...

    2006 charging at 15.8V

    I come bearing possible good news. Swapped the alternators, left the second one (that was originally in the factory spot) unplugged, and voltage is the correct 14.4 ish. Granted, this was while the truck was already warm and a very short drive, but tomorrow morning will be the real test. As of...

    2006 charging at 15.8V

    Kinda long these lines, I’ve been thinking of how to isolate whether it’s a possible tuning/wiring issue, or a bad alternator possibly. So my remedy for this currently is to unplug the factor alternator. Now this does give,e a battery light and vehicle not charging warning, but it does actually...

    2006 charging at 15.8V

    Okay so battery voltage after sitting overnight is 12.86v. Unplugging the second alternator plug did not help, still seem to be getting well over 15v. This was even just sitting at high idle. I do not have KHB listed in my RPO codes. Closest thing I have is KNP and KUP. A few interesting...

    2006 charging at 15.8V

    As far as I know yes, but I don’t have the actual build sheet. If it’s not, they took time to make it look 100% factory. I’ll try unplugging it next time I leave

    This was only about an hour of sitting. I’ll check it in the morning for a more accurate reading

    2006 charging at 15.8V

    Unfortunately the amp isn’t adjustable. Crutchfield is sending another one just in case (Infinity 7005A) but I’d guess the issue will still be there. So, after sitting for a couple hours last night when I initially plugged up the multimeter with the key off it was somewhere between 13.5-13.7...

    2006 charging at 15.8V

    Hey guys. So this truck has actually done this since I got it. It’s a factory dual alternator truck, no intake heater anymore, and currently has two new batteries in it, though it was the exact same with the old Dekas I’ve had since I got the truck 4.5 years ago. Measured with a multimeter going...

    Need help with diagnosing an ABS issue

    Thanks James. I’ll try to do a bleed when I find someone with a scanner that’ll do it. And thanks a million for the troubleshooting steps

    Thank you for the PDFs and info. This is exactly what I was needing to figure out how to begin diagnosing.

    Need help with diagnosing an ABS issue

    Conclusion: something in the ABS system is messed up. I’m asking for help on how to diagnose which part of the ABS system could be causing the issue because A - I do not have a ton of knowledge on all of the ABS system parts or how exactly they could cause an issue like this and B - I don’t want...
