Doesn't that connector control the amount of volts is put out like if it's not getting 12v it puts out more and if it's getting to much it puts out less? Taking those out doesn't run the Volts higher? I feel like a capacitor would be a safer fix but more expensive. Or is there something else I'm not thinking about?

Try moving the ground wire away from the engine bay ?

[@robmccormick4403]

Hey Matt I've watched your video and you said something about your lights dimming I don't think you need to hire full amp alternator I found one guy who left the comment just like I'm going to leave you you take a new ground wire to your high beams your high beams and the low beams used the same ground and if you put another ground on it it stopped my flickering I do not have capacitors set up on it which was only thing to recommended by everybody who wanted to sell me a million dollar capacitor but if you know anything about electronics capacitor is not going to take care of the big base boom anyway I thought I'd give you that little cheap fix run a new ground wire from the high beam ground to the chassis oh and it also when you hit your high beams all four will come on at once which will light up the side of a mountain which I'm very happy with anyway I seen that from some body's comments and it worked on my 01 GMC Sierra give that a try before you buy a capacitor or an or a alternator

So I have a 2013 Yukon Denali I have been dealing with the amps cutting out while driving since I finished my build 2 months ago. I’ve replaced the battery, the alternator done big 3, augmented ground ect nothing fixed it until today when I came across your video! I went for a ride with my wife and she took a video of my volt meter and as soon as it spiked to 15.6 it would cut out so I unplugged the alt and it hasn’t happened again so far! I wish we could fix the battery light but just having no cutting out is making me super happy right now. So thank you

[@piercesteadys6601]

As stated by previous person, the factory’s computer is controlling the alternator for battery conditioning, and fuel economy. I had a Chevy van that did this. However, the voltage would drop when the AC would cycle on, or accelerating up a hill. I called the dealer, & they said it normal to see a voltage fluctuation. As far as a fix, check with a local reputable alternator repair shop. Keep in mind that high wattage amps require large amounts of current to operate efficiently. Rule of thumb, if your planning on a high powered stereo system, be prepared to up grade the power requirement for your system. Car audio is a addictive, & expensive hobby. I know this because I have been a car audio nut for the last 32 years. Thanx for the informative video.

Just add a Capacitor, it’ll prevent the high draws from electronic system. Don’t unplug your alternator, you’ll burn up your battery or other electrical systems.

@@MattsShop installed correctly capacitors work at preventing voltage spikes and drops. Under high demand your system voltage becomes too low and can cause serious drive ability issues.

The problem though is without computer control, the alternator will be overcharging your battery which will reduce its life. A lot of modern cars are designed for smart charging the battery to prolong its life as in, when the battery is fully charged it stops charging it. Good video.

[@MattsShop]

Yea, it's different on every vehicle. On this one it goes back to 13.8 Volts max when you unplug the regulator wire.

Firstly, thank you for taking the time to upload this video. It's been extremely helpful in identifying what's been semi-problematic with my 2008 GMC Sierra. Second off, I think you answered all of our questions here, if you want a permanent fix, all you need to do is purchase an amplifier that has a maximum voltage that is over 15.5v correct? This should allow the amp to avoid protect mode on these particular trucks?

Then your electrical probably isn't beefy enough. You probably have a weak ground.

Voltage regulator keeps voltage steady whether you're doing 20mph or 100. Putting a smaller pulley on a 6.0 Diesel overrides the computer but idk about others.

[@MattsShop]

Not on these charging systems. The computer ramps the voltage up or down depending on the demand. That's the problem. It ramps the voltage up too high for some amps.

[@Scorpio-tn4vy]

@@MattsShop i see what your saying. I just run a higher amp battery than oem and a capacitor. When its time for an alternator I'll put a heavier duty replacement. It shouldn't though if the voltage regulator is functioning correctly. To high will swell that battery up and fry it.

I did the rare electrical 290 amp alt lasted a year and fried because its computer controlled charging...So alt can't give the current it needs to when the computer won't let it..They fight each other like a push and pull between alt and computer...Been trying alot of things but now I'm going to unplug the sensing wire and see what happens...There's no way it's going to over charge for me with the car amp pulling power and the 2 reserve batteries plus main battery

[@tjl8884]

Im curious if you were running a cap near the amps to store that extra charge which would eliminate that draw from the battery? It sounds like its hitting so hard its pulling lets say 20-30% from your battery which is triggering that over voltage/amp from the alternator so when the amps don't need that charge your alternator is still kicking out the extra amps trying to charge the battery back up to 90% or whatever? I never had a problem with my amps going into protect mode but I always ran a cap back by the amps.. It also eliminated my lights dimming and over all I think its saves the alternator or prolongs its life.. But I am no expert on any of this stuff just more into trial and error because I never did use a cap on my first install then I noticed the lights dimming at night with the sub hitting so I got the cap and it all smoothed out so it wasn't doing it anymore. But that was back in 2004.. These modern vehicles might be a bit different idk..

So disconnect the "sensor" or whatever youd want to call it and it'll think it's just normal so it doesn't peak in amps to over compensate thinking it needs more?

Exactly! It's not the amps that it increases though. It's the voltage.

If that's your voltage and it stays steady then the voltage is good. I'd make sure the speakers/subs are wired right. Are they wired to an impedance (Ohm) load the amp can handle? Are there any loose wire strands touching each other at the terminals and shorting out?

It could be hard to find out if it would work. I'm not familiar with the charging system on those trucks. I wouldn't just go unplugging many wires though. Have you tried unplugging the harness wire from the top of the alternator and then reading the voltage at the battery? If you can't find the wire in the schematic you might have to control the voltage a different way on those trucks. This is called a PWM charging system.

Anyways I bought a 300a high output alternator that was 2 pin and still had issues with voltage flucuations and my music would actually get quieter from it. I swapped the 2 pin regulator in the alternator to the older 4 pin style that GM has used for decades. Google how to excite the 4 pin but basically to get going you just hook up an ignition switched 12v power source to pin F or L can't remember which. Then the truck will charge at 14.4-14.8 all the time. I purchased a 14.7 set point regulator but most are 14.4. 10:36 Edit: disconnecting the 2 pin plug throws the alternator into a limp mode with a 13.8v charge always. Maybe see 13.6 on your dash= sucks.. also jumper the 2 pin plug together(connect the 2 wires going to 2 pin alternator) and it tricks the battery light on dash to go out.

[@MattsShop]

Do you have a bad ground or shorting anywhere. Test the ohms of your speakers and make sure they are 1 ohm, 2 ohm or 4 ohm with a multimeter. I've had blown subs do this before.

Hmmm....I've had this issue but with a dodge ram but the alternator is the same set up I get this shit off at high volume especially with my 350 amp alternator . I noticed the volume ts aren't dropping at the dash but amps are definitely cutting out into protection I'll have to pull the pcm harness plug and see if that's a fix I know it's not my wiring it's all solid . I never thought about over voltage.

[@danks2real314]

Did it work

[@georgec6228]

@@danks2real314 No the amplifier was defective was under warranty and swapped it out . Now the only time I have it cut out is when my trucks grid heaters are on an it draws power on cold start up days so I don't turn on the system until truck is warm or disconnect the grid heater . I think I screwed the first amp up I was tired when I installed it and accidentally swapped b+ for ground at the amp and when I hooked up at the battery it sparked I didn't continue to hook it up I immediately checked my connection back at the amp and realized my mistake but I think that caused the issue I ended up getting luckily... warranty...

[@Amanda-pw7ij]

Chevy charging systems are junk the real problem is you are discharging the battery too fast you need to add a second battery with a isolator and put the power wire on it that way the amp doesn’t back feed when the voltage rises back up also the signal wire is ran to the fuse block so the power signal isn’t getting proper voltage it needs to be ran to the battery to correctly function

Good amps need power point blank, an after marked alternator and a dedicated amp battery works if you have a strong amp needs more power 2 batteries may be needed

[@MattsShop]

Yea, I agree. It's just really expensive to do an aftermarket alternator and extra batteries. You are talking at LEAST $700 if you get good name brand stuff with all of the cables, terminals, alternator, and batteries. So I just unplugged the sensor and deal with it. If I was running 1000's of Watts and many more amps/subs it'd be worth it though.

[@Angel_Ventura915]

I need to try this for my 2012 Chevy Colorado. Ive been running a small SKAR 300 watt RMS amp with no issues fir a few months but last week it started going into protect mode constantly. Its very frustrating. I was going to throw in a different amp. I have another of the same amp in my Yukon. But I'll try this first

The ground cables go straight to the body, frame, and battery to get an awesome ground.

You mean the negative is connected to the ground on the truck. I hope you dident connect the postive side to the ground?

[@dannydd4849]

@@steveespinoza200 listen I have experience with electronics and audio equipment on cars the only issue I had was the video at 1.19 seconds or 1.15 you can see that all the wires going to the battery are black it's hard to identify which of the cables is the positive but in my experience in a car in the right-hand side part of the battery can never be positive because it's going to be closer to the body or Fender and that could make contact any given way or situation I don't even understand how they even get to tighten the terminal on the battery without making contact with the fender and if it would have been identified as positive red I would not have the doubt that the wire coming from the fender to the left side of the battery would have been positive that's how it should have been if the battery would have been in the correct position and not with the negative in the other side dangerously near the body or fender 🙄🤷‍♂️

You need to hook up a multimeter on Volts DC to see what is going on. Are your bolts dropping? You have a good ground?
