Good stuff! Thank you for your support and install. FYI, your application uses a terminal block regulator so if you ever wanted to up your voltage you can simply purchase the 91102R external regulator and it would be able to plug in to your Mechman alternator. 😇🥰

[@DIYAudioGuy]

That explains a lot! When I get those voltage drops it happens when I stop at a red light, the voltage dips and then I jumps back up above 14. It happens no matter how much power I am drawing. If upgraded batteries don't even things out a bit I will look into that regulator.

[@blakebrockhaus347]

One thing I have wondered that I hope y'all could help with. How much extra wear is caused by adding batteries. Obviously a 2k amp on a stock battery is gonna cause more wear on the alt than that same amp with a large agm. But when you get into the territory of guys running a 12k on say 100 AH of lfp and a stock 120 amp alt, how much faster will that actually wear out the alternator?

[@tonyb022377]

@@blakebrockhaus347 it depends on the level of battery depletion and the number of times that has happened. Adding batteries is a good way to absorb high percentage battery depletion. When you're only "topping off" a few batteries vs. Completely charging a single battery, its much easy for both the battery(s) and alternator.

[@scottiffanimccord1509]

@@blakebrockhaus347 A stock 120a alt running one 100ah AGM, powering a 12k is never a good idea, 1- you you'll run the system into low voltage causing premature failure of the amp, deck DSP, and any other equipment you maybe running. Your AGM will never have a chance to recharge to its full capacity causing it to fail in a short time and finally your going to burn up (over heat)your stock alt because your forcing it to charge at 100% all the time. PS I would say a 2k with the same power source would end with similar results with long listening sessions. Lithium is a no brainer. the JP 40 in the above situation would cure all of my points, maybe 2 JP40s for the 12k and you could keep you stock alt. I hope that helps.

The battery being replaced will absolutely help since it stores all the power! ( pop the cell caps I'll bet the fluid is low ). Now with that being said, maybe you did it of camera but for the people watching as well as you bud. When doing the big 3 first always super clean all connections including the factory's and use terminal protector or clear coat the crap out of them!!!!!!!!!! And most definitely buy new terminals ( there's many options, my personal favorite is the terminals with the post adapters. ). This will completely fix the voltage drop! Lastly the fused link is a safe idea and always a good idea, however doing the upgrade completely and cleanly it isn't needed because most vehicles already have a fused power wire and if it goes it will tell you far faster than the new wiring fuse ( since your putting a bigger wire and fuse than the factory). Now if your running a old vehicle with out the fuse than pro tip. The alternator wire to battery must be fused, close as possible to the alternator and make sure your fuse is matched to the alternator amps! Then the power wire to the amps will match those and Lastly grounding the alternator casing should be upgraded as well. ( the big 4 ) or you will create the bottle neck that will cause the power wire to heat up. Lol actually 1 more peace of advice for everyone. If you're going to do the big 3 never use a smaller wire than 4 gage ofc. But really just use 0 gage ofc and never look back...

Odyssey agm under hood, optima yellowtop, xs xp2000 and ioxus ultracap in the trunk and I still drop to low 13s full tilt. I'm switching to lithium soon but I feel like all I have should be able to maintain mid-high 13s if not 14s full tilt.

[@HifiVega]

Great video! The install turned out 🤟

[@DIYAudioGuy]

The wire was fantastic.

[@moejaassen]

Sorry if i ramble here. Great stuff in this video, definitely signing up for skill share! I can't use the hydraulic crimper on my own because it always shifts and gets very frustrating as you mention. So the hack I found for large gauge is to use my vice with a steel pellet placed in the center of my crimp spot. The steel pellet is very important! I've found it works just as well as a hammer die if not better and less work :) Im running stock electrical on my new model sierra which is a factory upgraded 220A alt and large factory agm with that beautiful blue new jp23. I am seeing voltage down to 13.3 on the hardest bass hits then quickly rebounding when the alt is charging wired down to 0.5ohm to clipping. The smart charging on new GMs can be a pain but it's also tells me my electrical is sufficient when it still sometimes goes into "smart charging" which maintain a 80% battery charge and lowers the charging voltage in this state to reduce the draw on the engine to increase fuel economy and battery life supposedly. I still want to add an ultra cap near my amp because I am dripping over 1v on those hard hits but I don't think its absolutely necessary.

[@DIYAudioGuy]

Yea, maintaining voltage is important!

[@mechmanalternators]

One of our 320 amp units would be a nice upgrade for that setup AND it would come smart charging bypassed out of the box. While your OE 220 amp alternator is certainly a good one, it is still the old 3 phase round wire technology. What that means is it is less efficient and makes less power in lower RPM's. It is probably around 130-145 amps at idle and around 185-195 amps heat soaked/operating temperature. For example, our similar amperage 250 amp unit will make around 190-210 amps at idle and around 255-260 amps heat soaked/operating temperature. So while you're only "seeing" a 30 amp difference, there is much more under the curve and in the operating zone. The good thing about going with a 250 amp unit is the same size pulley as your OE unit so you can reuse your stock length belt. A great bang for buck at around $400 considering whats out there now.

[@moejaassen]

@@mechmanalternators Wow, thanks for the info! I've been curious about the curve on the 250A. I guess I've been reading older forums, because I was reading that you weren't sure how the alts would react with the smart charging tech in these trucks, and the largest you made was a 240A (if I remember correctly, but I guess that was probably the 250 mentioned.) Sounds like you have it all figured out now with them being bypass ready and larger! I will be calling to talk to a tech about the 320A assuming a tech can assist with sizing the belt for the reduced pulley size. I would definitely like the extra available power for future builds.

[@davidschreckengost7959]

When using the lug , blow torch it use a little bit of sawder and then crimp gets a better connection and way easier to crimp.

[@brendenperry3770]

I have a 09 escape that I put a 250 amp ho alt in to run my subs and mid and high amp. When it’s at full tilt one song I tested made the voltage drop to 11.8 but as soon as the alt kicked in it pushed the voltage right up to 15.3

[@Grommet2007]

Just a question, I see a lot of people using fuses instead of circuit breakers for their car audio power lines. I'm curious as to why, as the circuit breaker is re-settable and it provides an easy way to disconnect the power to the amps (by just switching it off).

[@DIYAudioGuy]

Honestly, I think it is because that is the custom. Everybody does it because everybody does it.

[@Grommet2007]

@@DIYAudioGuy Not me, LOL. For as long as I can remember I've been using circuit breakers. I've got a 200A one in "Matilda" right now that's been there for almost as long as I've owned the SUV (15 years). I guess fuses are a bit more aesthetically pleasing than circuit breakers, but I'm definitely a function over form guy, particularly when the chances of getting a replacement 200A fuse locally are basically zero. No bass for a week while I wait for a replacement to be shipped? Not happening :-).

[@mechmanalternators]

The main issue we see with using those is voltage drop can happen with the wide variety of cheap circuit breakers. Same goes for battery isolators, it's just another pot for potential voltage drop. The "fuse" is usually the goto as it is cheap, more readily available and less chance for voltage drop due to cheap manufacturing costs.

[@Grommet2007]

@@mechmanalternatorsInteresting. Battery isolators are a bit different as those have electronic components in series with the power feed that will cause a voltage drop. With a circuit breaker, all the power feed sees is a switch. I guess one could argue that a fuse only has two points of contact while a circuit breaker has three (the connections to the circuit breaker and the internal switch), but that third point of contact is usually very well protected .... FWIW, "readily available" is subjective. if I replace my 200A circuit breaker with a fuse and it blows, I will have to wait a week for a replacement because I will have to have one shipped - no one stocks that locally. OTOH, I've been using the same 200A circuit breaker for the last 15 years so never had to replace it, and the convenience of just being able to switch off the power to the amps (as opposed to having to pull a fuse or unscrew a cable from the fuse holder) is just too much to give up :-).

[@mechmanalternators]

@@Grommet2007 100% on the money. As for your 15-year-old circuit breaker.... unfortunately, there has been a decline in quality/quality control of many of the electronics over that year span. :( In a situation where a disconnect is needed, I personally just use high amperage marine grade on/off switches. I use these instead of relays as well on my personal off-road vehicle.

[@blueduck8431]

Great video. You can find some of the higher-end AGM batteries have positive and negative side mounts and top posts. They are a great option for connecting many power leads and grounds. I have an X2-Power AGM setup in my truck.

[@brianwaller7383]

As a diy myself if anyone wants a cheap way to add buss bars to your batteries. Just go to Home Depot and get mending brackets. This gives you 3-4 extra “holes” to install lugged wires. Most places will charge $50 for a 4 lugged buss bar.

[@DIYAudioGuy]

Thanks for the tip.

[@2011joser]

Watching this great video with a little bit of envy. This core part of the big 3 won’t work on the vehicles I install on. Mechman doesn’t even make one for the later model Hondas we drive. Those Hondas have computer controlled alternators that allow voltage drops irregardless of the output capacity of the alternator installed. There is a workaround but it is very complicated and definitely not for novices.

[@DIYAudioGuy]

That sounds like a royal pain.

[@tonyb022377]

Sadly, you're right. LINBUS integrated computer charging is very finicky and doesn't like being messed with. Usually just adding batteries is an good, reliable and somewhat economical bandaid.

I've fought alternators brackets before... that hammer and threaded rod is the ticket

[@lv9530]

If you are grounding from the mounting bracket on the alternator do you even need to do the engine ground?

[@DIYAudioGuy]

I've seen that done before. No, I don't think that you need the engine ground if you're going to do that.

[@scottiffanimccord1509]

I would say it depends on the overall power draw of your system, but DIY guy is right probably not, a 390 alt can only produce 390 so one short run of 0 gage OFC from the battery to the alt is enough, but Rob (Hifivega) the guy the made the big 3 kit, included this extra peace so having the battery grounded to the frame is just the best thing to do hands down.

[@blakebrockhaus347]

Since the alt grounds through the engine block, upgrading the alt ground is functionally the same as upgrading the engine ground (In theory) there may be other things idk abt, but electrically it should be the same

[@mastermind5482]

3 grounds body to battery, frame to battery, alternator case, bracket to battery.

[@scottiffanimccord1509]

@@blakebrockhaus347 There is a reason the factory has multipule grounding points engine, frame and body, it is because of rubber motor, Transmission mounts, if you want to ground the alt to the fame you must run a dedicated ground directly to the frame. PS the frame is the best grounding point on trucks, I hope that helps. Also, most modern vehicles have cheap cast alloys under the hood with gaskets, and treed locker, anti-seize on the head bolts rendering an engine ground in my opinion a poor choice. But opinions are like diapers there full of shit and usually stink LOL

[@mechmanalternators]

@@DIYAudioGuy You can either do the external regulator thing (plugs in) OR we can rebuild your alternator with the more standard GM 4pin regulator which will have your voltage at a steady 14.6-14.9 volts. You'll need to install a 12v switched source wire from the pigtail we provide to turn the alternator on and off as the only other hookup.

[@enntense]

Little late here, but there are issues with doing and Alt upgrade. In my case it was a 400 amp alternator in a 2015 Ford Taurus. What no one tells you is all modern cars use a battery management system. In the 2015 Taurus case its based on the negative battery terminal. It's an amp clamp that senses current. Whats going to happen if you do nothing is the sytem will start and look fantastic! Untill the BMS adapts to the new current level. IE after about 8 hours. At that point your voltage will mysteriously start to drop off. The system is seeing your battery hitting its 80% charged limit and deliberately throttling alternator output. No what anyone doing this is aiming for. I grounded the negative to the frame and the alternator to the same point. Now you have 2 choices. Use FORSCAN and disable BMS, or simply unplug the current sensor. Things you learn on the way...

[@DIYAudioGuy]

That is a good point in something that more people need to talk about. I very rarely see more than 14 volts in my vehicle because the ECU controls the alternator. At some point I'll need to add a regulator.

It's a vehicle specific question. Let's see your factory can put out a hundred amps. That's only peak output, not idle output, and your car is probably going to need 75% of that power to operate. That leaves 25 ampers of current to operate your aftermarket gear.

No you don’t have to take pictures of the belt routing unless you really can’t remember. Serpentine belt routing is easy, the belt has a smooth side and a ribbed side, some have 4,5,6 ribs. Now your motor has pulleys with the ribbed grooves and some smooth tentioners and the only way to route the belt is to place the ribbed side of belt to ribbed pulley those must face one another and same with smooth or outer side of belt and tensioner pulley. If ribbed side of belt is making contact with a smooth tension pulley or vice versa it’s wrong.

[@shermbot9776]

I'd guess the cathode plate in the positive side of your battery likely has degeaded over time. If the alternator can't force enough extra power into the positve terminal of the battery, it results in too few electrons dropping from the cathode and then less electrons are then available from the negative terminal where the annode is housed. As the cathode fills with electrons, the chemical attraction between the negative terminal and positive terminal is reduced and is seen as voltage drop. The alternator can be thought of as the pump that pushes electrons to the negative terminal so they can be used to do work in the circuit. Basic chemistry supports that electrons flow from negative to positive in a DC circuit powered by electrochemical batteries like agm, lithium, or lead acid.

[@DIYAudioGuy]

That makes sense, the next step is a new battery.
