Thanks for showing everything with details and not overlooking anything. I hate it when someone does a video like this and skips something like a diode orientation. Did you do it on a factory alternator? If so do you recon it's still as reliable, nothing wrong with it so far? I might try to add 2 of these to get up to 15V. I dont want any more because I know it will screw up my alternative fuel computer but I want to use that extra bit of lithium capacity since I don't have space to add more banks.

[@Husky_Shane_BassHead]

I have a Brand X 240amp alt, haven’t had any issues and the car has been running like this for about a year.

[@talat6006]

BTW, for the Inverter you could use the same diode going to the Inverter to drop the volt back to its specs.

[@Husky_Shane_BassHead]

Good idea! I’ll have to try that.

[@talat6006]

@@Husky_Shane_BassHead you may want to use a higher amp diode though because the Inverter line got to be a hot line and not a sense line

Why not just split the wire put male on 1 end female on other then make a small wire with 2 diodes and same thing male on one end female on other and plug that in😂. Great video 👍👍

[@talat6006]

Hi Shane and thank you so much for this vedio which inspired me to try it and it worked partially with one diode 4004 and got a raise of 0.23v, I was hoping for 14.7 and my initial volt was 14.3 , with a hyundai tucson diesel, an odyssey ODX-AGM34R which needs 14.4 to 14.8 v charge. When I added 2 diodes using connectors I still get 14.53 max same as one diode !! Do you think I should solder the 2 diodes in between, or may be my voltage is ECU controlled to max at 14.5v only ?? Cheers, Talat

[@Husky_Shane_BassHead]

I soldered mine, but I doubt that would cause a noticeable limitation in voltage.

[@talat6006]

@@Husky_Shane_BassHead HI I did that next and same result it looks like my ECU is controlling the alternator to.max at 14.5v, for the time being its OK for my agm, my next one gonna be an LFP and I am not sure if this is gonna be sufficient

[@Husky_Shane_BassHead]

@@talat6006 hmmm, yeah I don’t really know how to bypass that either.

Did you have to use a step down module to keep the cars electronics happy?

[@Husky_Shane_BassHead]

@@brandonkruger9040 no. It seems fine. Never had an issue, no dummy lights either 🤷‍♂️

[@Mr.Weatherspoon]

umm you know you can do the same thing by taking the sense wire off. and running all the way back to the back battery. it will bring the alternator up and down when needed in stead of always being kicked up when you don't need it and there's no load being taken.

[@Husky_Shane_BassHead]

I didn’t know that actually. Good to know though. I might try that!

[@Mr.Weatherspoon]

@@Husky_Shane_BassHead yes sir an old alternator repair shop trick if you Don't have an external regulator. Im having to do the same. You can run a remote wire on the outside of the car loose hanging just to try it out.

[@scamchan]

So the voltage doesn't mess with other electronics in the car?

[@Husky_Shane_BassHead]

It doesn’t seem to. I’ve had it like this for several months now. It’s my Daily Driver. Haven’t had any issues.

[@scamchan]

@@Husky_Shane_BassHead Awesome So what exactly are the diodes doing?

[@Husky_Shane_BassHead]

@@scamchan well, I don’t fully understand it but. Basically, the sense wire is what sends the signal to the regulator to tell it what voltage to put out. The diodes are resistors that lower the voltage that the cpu is sensing so it tells the regulator to up the voltage because the diodes make the cpu think it is in a state of too low of voltage.

[@scamchan]

@@Husky_Shane_BassHead Thank you that makes sense. Thanks for the video. So you added all that red loom as your wiring to the amps and stuff?

[@Husky_Shane_BassHead]

@@scamchan yes. I used the red loom to make that it’s a positive run, all the 4/0 I used was black so I used loom as a color code.

[@TrunkThunderLithium]

So find our what the ohm rating is for those diodes are so you double that number or even triple in your case then use just on of the original ones an try just maybe 2 doubles rated ones an see how it does. To many diodes to many points of failure

[@Husky_Shane_BassHead]

That’s a good idea. I’ll do that. Thanks man!

[@mikeclark2045]

I guess I’m an idiot. My car has a three wire plug and when I tested for voltage with the car off I got no reading across the three but with the car on I got a reading.

[@Husky_Shane_BassHead]

Huh, what car is it?

[@schwartzenheimer1]

You're not really reading the charging voltage until the batteries catch up. Current is being supplied to the batteries, but they limit the voltage until they charge completely. Let it run, and see where it settles, and that's your charging voltage. BTW, each series diode adds ~0.7 volts to the charging voltage.

[@JmsJing]

.3 to.4 each diodes

[@deanskeez9472]

Would this work on a smart alt or one that is controlled my the ecu coz i have 3 pin coneter since its a honda

[@Husky_Shane_BassHead]

Don’t quote me on this but I think so. As long as you can find the sense wire.

[@deanskeez9472]

You overcharge the starting battery

For the young bucks out here getting started this does not work with a stock alternator

[@Husky_Shane_BassHead]

@@FrankStPeter can you explain? I’ve seen some videos of it working with a stock alternator. I’m pretty sure it’s vehicle dependent.

[@FrankStPeter]

@@Husky_Shane_BassHead I have a 2004 Yukon XL with 150 amp alternator I tried three diodes by themselves My voltage actually went down to 14 volts I did some more looking around to see if anybody had an answer and someone said 47o OHM resistor The sense wire voltage still dropped down to 12 volts,, The only commonality in all the different videos were aftermarket alternators

[@Husky_Shane_BassHead]

@@FrankStPeter ok, fair enough. I’ve never actually tried it on a stock alt. Maybe it has something in the internal regulator that won’t allow it to charge higher 🤷‍♂️

[@itdoesntmatterwhatyourname6128]

⭐️ Can anyone help me out? I have a '03 Crown Vic Police Interceptor & the charge voltage is controlled by the PCM. I do already have a 350 amp ho alt & big 3 upgrade. I know these vehicles are common so surely there is someone who will see my comment who will be able to give me factual information based on my vehicle.? Can I just add diodes to the sense wire on my vehicles model? I do remember it having a sense wire from back when I installed my ho alt. But I think it also has a wire called "PCM Regulator" as well. Its 10:30 p.m. cold & dark outside so I'll double check it tomorrow when its daylight.

[@Husky_Shane_BassHead]

@@itdoesntmatterwhatyourname6128 I have no personal experience with that specific vehicle. You could see if someone could build you an externally regulated alt for that car. BrandX or Mechman would be who I’d check with first. I also know Brand X makes voltage control knobs. I’d reach out to him and just see what he says

[@TrunkThunderLithium]

Get a 24v inverter or one rated for 16v ones that do both work even better 😂

Gosh dam broo again the music is loud in the video too😮

Yeah sorry man. I didn’t realize that was happening when I was editing some of my earlier videos.

[@charliefrancis6438]

What size and rating for diodes? Too get to 16.2 volts ?

[@Husky_Shane_BassHead]

I just ordered these off eBay. I share the part number in the video. You just have to keep adding diodes until you get the desired voltage.

[@TheLostAdventuress]

Instead of stacking diodes or now that u already did, now just order 1 single diode of the right size

[@nathanpressler9790]

Each one should add .5 volts the way I understand it. I see what your saying not sure tho that will make it work gotta run them in parallel

[@FrankLowe1949]

This is not TRUE !! it can not be be done that way .

[@Husky_Shane_BassHead]

Explain the video… of me doing it that way.

[@danielkearns3600]

Your just fooling voltage regulator by seeing .5 volts less for every diode and it increasing the output. The no solder connections and the wiring nightmare is a mechanics worst nightmare. You really need to simplify and make a wiring diagram to let anyone who works on your vehicle what is going on

[@Husky_Shane_BassHead]

@@danielkearns3600 I understand how the diodes work, the connections are soldered, the person who works on my car is me.
