    Alternator, battery, or amp meter?

    UPDATE: I ordered a JS Alternator (320amp) and installed it on the truck. Preliminary results show the flicker completely gone. Both in the headlights and interior lights. I'll obviously do more testing as I drive, but I think I solved the issue. I also found no corrosion on the negative...

    Alternator, battery, or amp meter?

    Correcting the wiring and of course no change. I did notice the truck almost stutter at idle, which I believe could point to my alt. I hooked an amp clamp and only got 55amps with headlights, sound system and misc accessories. I also noticed fresh corrosion on the battery terminal and I cleaned...

    Alternator, battery, or amp meter?

    After an exhaustive couple of days I think I have detangled the mess of my electrical system. It all started when I did my system initially. I did my big 3 the old fashioned way, NOT properly incorporating the RVC unit. I also didn't use a smaller serpentine belt. As a result I think I fried the...

    Alternator, battery, or amp meter?

    The battery is about 2 years old right now, and I have had to clean corrosion off of it at least 3 times. The first 2 times was pretty bad and what prompted me to upgrade my ground wires and terminal. I purchased a foxwell battery tester that can test the battery under multiple conditions as...

    Alternator, battery, or amp meter?

    Alright here's my report on a ~20 minute drive after unplugging the RVC. Volts were steady between 14.4 - 14.7. Headlights flickered heavily for the first 5 minutes, then almost completely went away for the rest of the drive. Overall about 70% better but still not eradicated entirely. Volts...

    Alternator, battery, or amp meter?

    Two very interesting and insightful posts. Thank you for them. Currently the headlights AND my interior lights dim, so it's definitely through the entire system. I am going to unplug the RVC and go for a drive and see what happens. This is why you don't buy crap parts :D because I have a lot of...

    Alternator, battery, or amp meter?

    Regardless of where the power draw comes from, all power goes to ground. That's why the rvc is on the negative wire. As to your question about the voltage, yes. With no load besides driving and audio my volts are around 12.7v-13.1v. With headlights on it jumps up to about 13.4v-13.8v. I'm...

    Alternator, battery, or amp meter?

    After doing some research I think my RVC is the problem not my battery, alternator or amplifiers. It seems the headlight diming is an issue regardless of OE vs aftermarket with these trucks. My alternator definitely works properly as it fluctuates from 12.7v - 13.8v depending on load. Without...

    Alternator, battery, or amp meter?

    I redid my negative cables. Alt to body, battery to body and battery to engine. All 0 gauge OFC. My alt is running 0 gauge straight to the battery for power as well. My amp wiring could definitely be the culprit as I installed it a few years ago when I was more of an electrical novice and to...

    Alternator, battery, or amp meter?

    ** EDIT: I curiously went back to the alternator listing and right there it mentions using a smaller belt. I am not currently. So first thing I am going to do is get a shorter belt and see if that tightens things up** My lights flicker (ext and int) with my bass and it's time to fix it. I have...

    E85 or regular gas?

    This went off topic, but to answer the E85 vs Regular Gas... E85 hands down. I have used it now for over 3 years consecutively and on a GMT800 and GMT900. The trucks are way peppier, smoother, and smell better. I haven't lost a significant amount of MPG in the process either. I bought my current...

    Catch Can for 2006 Tahoe 5.3

    A catch-can with a good throttle body/maf cleaning might make everything feel a bit better. Especially if that PCV hose is cracked or on it's way out. But it will definitely keep oily vapors, and ***** engine oil from getting sucked back into the intake which should keep everything clean over...

    Battery not charging

    Definitely parasitic draw or short which could be any circuit. I tried to attach two videos but there's a great one by HumbleMechanic and Junk DIY Guy. Titles are: The BEST Way TO Perform a Parasitic Draw Test and How to find a short in a modern car fast and easy (The correct way)

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    Directly off the battery with that 4awg wire. Yes it's an 0 gauge wire. It's in the picture there, but I'm planning on redoing my power terminal as well since that little 10mm bolt doesn't inspire confidence. I just have to plan out everything since there's 3 or 4 connections I have to make and...

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    Re-did my grounds because I noticed constant corrosion on my negative terminal and my lights started dimming. I think I solved my headlights dimming but my interior lights are still dimming with my music… I’m trying to understand how that can happen given I upgraded all my ground to 0 awg OFC...
