Awesome, juat remember to also upgrade the feed wire, the small skinny wire going from the red positive box to the alternator. The bigger the wire the better. I used smaller wire in the video since i didnt have any more wire laying around

I did something similar with two batteries. I isolated one battery with a solenoid and used circuit breakers/fuses for safety. I hear the alt you used are top-notch.

Thanks for the video man, about to upgrade my alt and that fuse tap explanation was helpful.

Thank you homie 🙏🏼 Best video on how to do this 🔥🔥🔥🔥🔥

Would be good if you threw a meter on to see where your voltage was resting and even to see the amperage output from the alt. ✌️

Haha exact same heat gun and I think the same crimper but mine isn’t branded. Epic

Good bro, good attention to detail

Is it best to add onto the OEM wiring or replace it with the new wire? And if I wanna fuse the ALT should it be close to the battery?

What size belt did you use ? I got a 02' escalade 6.0 going to be doing the same thing.

Did you have to put a resestor to that 12 volt wire to the 7.5 fuse?

Did you have to buy the 7.5 fuse I have a 01 Silverado 4.3 and got a 400 amp mechman just trying to figure out because your Tahoe looks the same style front end of my truck and this question is for the ignition switch

I bought a Mechman 400 amp for my 2000 Silverado but I replaced the factory alt with a Top Street Performance 220 about a year ago and when I'm driving the Top Street is steady at 14.4 to 14.6 and at idle about 13.6 to 13.8. I'm running 4 Wolfram amps with a W7500 @ 4 ohms on a single Wolfram AU 15V2 (2500 rms sub) but I have 2 of those 15's but only installed one. On the dyno video I saw that W7500 did 3817 rms @ 4 ohms and over 6700 rms @ 2 ohms that's why I bought the Mechman because I'll be running both subs at 2 ohms. I'll be running the Mechman strictly for my sound system directly to my rear battery (a Northstar SMSAGM480) as a dual alt setup with the Top Street running the truck's electrical system. I even upgraded that same factory wiring you replaced with GP Car Audio 4 gauge ofc because the ring terminal broke during installation and I had some extra wire I had from installing a small system in my wife's SUV. I'll also be running 2 runs of Sky High ofc 1/0 gauge from the alt to the rear battery. I was wondering how's your alt performing?

How's it working from beginning to now???? I also have a Tahoe 2 subs , 2 amps, 6 mids, two tweets, estimated around 2800 RMS.

Where did you get the connector for the plug? They are wanting me to splice mine and reqire itb

Good video keep it up!!

Thank you so much for showing me the right way bruh

Just wondering if you used the sensor that the original ground wire ran through before it connects to the battery . I found on other videos if you bypass this or even if you keep it and run extra grounds to your battery it can bypass the sensor with a easier route and your battery will drain a lot more before charging . Maybe Mechman has some circuitry where you dont need the sensor anymore ?

@fusiondensity3287

I had high voltage charge after i installed my mechman 370 elite because I didn't hook up the blue wire to the fuse box at first. It was putting out 18 volts and my power window switch got smoked and all the lights super bright. Once I hooked the blue wire up it worked perfect. After about 6 months it started charging at 18 volts again. I took it out and have to send it in for repair. It might be the voltage regulator. I don't know.

Does the belt matter when upgrading Alternators bc Ik they have different belts for dif amps, Or does that not matter?

@ronkrohne9253

The reason for the different belts is due to the size of the different amp alternators. The center of the pulley of a 145 amp sits higher than a 105 amp. So the 145 needs a little longer belt.

The reason why Mechman relocated the lug on the alternator is so that you would have to replace that wire. You should always replace that wire with the correct size. If your going to use 0/2 gauge wire for the power and ground then you should use 0/2 wire for that to.

The length of 8ga. wire he used is not a fusible link as is the 8ga. OEM one. There is a reason that it is a fusible link. Like to prevent a catastrophic fire/meltdown. Also the 2ga. positive wire from the alternator to the battery should have an inline fuse holder and a fuse of the appropriate size so if something were to go wrong in the circuit it would blow and hopefully save the entire truck. Mechman shows this fuse in their drawings. I just ordered and got a 240a alternator from Mechman and before I pulled the trigger I spoke with them to ensure I had all my ducks in a row in regard to wire size, fuse ratings, etc.

The big 3 is just the wiring upgrade. Bigger power wire from alternator to battery and then bigger ground wire to ground body, frame and engine together

Where's the rear of the alternator ground at? You are running a 400 amp alternator with a crap ground. Don't be amazed if that alternator goes out due to a poor ground kid.
