Mechman Alternators

Something wrong with my Mechman?


Recommended Posts

let´s just hope that, after i install that negative run , my voltage doesn´t drop below 12.8 - 13v using a single battery and 1600 wich isn´t bad at all :)

Curious to see the results after you install the negative run. Been lurking this thread since you posted it. lol

:popcorn::peepwall:

haha don´t worry, i´m gonna post some updates as soon as i can, i already recorded the voltage dropping to 12.5v now, there´s gonna be a before/after video for sure, fingers crossed!!

That's why the big 3 works..it upgrades your ground from motor and battery...the aternator back half case is the ground of it.it usually just uses the bracket as the ground through the engine block to the frame..put a 0g wire or 2 from mounting bolts to batterys..also do big 3 sir and how are

Exactly that, i already have the big3 but i don´t have that 0 gauge run from the alternator to the negative of the battery, i guess i´ll have the big4 then lol, i´m doing good old friend, what about you??? i miss your m4a´s :(

Good to see that you have an idea of whats wrong and how to fix it. Everyone makes mistakes that's how we learn. :drinks:

Yeah man, there are a few things that i´m good at and there are A LOT that i´m not, this one is one of them, and also, WALLS!! haha man i need to build one ASAP lol , cheers buddy :)

Man, hope the ground fixes you up. I know my alt is not a mechman(yet), but I noticed a pretty big difference when I added the ground. And I didn't even put it on the battery yet. So hopefully this will fix you up! :drinks: And I think I'm gonna go add another ground cable to mine now too! :clapping:

I tested the m4a and man that´s a monster amp, but having 2 7.5k´s is just CRAZY, very nice upgrade indeed, you use a single 400 alt right? 12v system or you have some crazy step downs? hehe

I´m using a single DD m2a @ 0.5 ohms right now, i have 4 runs of 0 gauge that comes from the single hc2400 on front to the buss bars on the back, remember that i used 2 batts on the back but i started testing the SPL Gains topic and i haven´t came back to 3 batts again, so i have my 4 runs of wire to the buss bars, and from there, to the amplifier

Yeah mate, same here, glad to know that you got a big difference by adding that ground, if that´s the case, i´m surely gonna add the best wire i can get, maybe even some kick ass 2/0 welding cable lol.
