extremeauto Posted December 11, 2011 Report Share Posted December 11, 2011 (edited) I'm not gonna gang up on Mechman as my issues are really at idle, on my low power at 1k rpm and up I'm getting 14.6-14.9v ... Soon as I get to 700 on dash it drops to 13.6-12.7-12.3-12.2 .... Apparently my car sucks??? hmmm sound like my 200 amp universal mechman i had to send back and PAY to have fixed... Were you the original owner? If not you are not covered under warranty. When I had an issue with mine they fixed it within 1 business day and was all covered under warranty bought it brand new from matt @ mechamn was told i used the wrong ring termal on my power lead from the alt.... i paid for the repair and bought a 0 gauge power wire from them ...hopefully it was my fault ora fluke and i will have no more issues ...sad thing is my stock 70 amp alt ahs took its place for the last 2 month and is holding like a champ.. the mechman lasted 2 months:pardon: Edited December 11, 2011 by extremeauto Quote 1995 Honda passport 3.2 4x4 Frankenstein on a budget ballistics sound deader (roof only so far) kenwood mp3 usb audio control 3 (upgrading) hifonics mx-3 3 sets of massive px5 5.25s 3 sets of massive tweets phonix gold 5.25 componets x2 massive nx4 nano 200x4 mids sony xplod 600x4 watt high's 2 Fi bl fully loaded box walled @31ish hz 13.2 cube box/wall massive DB8000 Excessive amaperge 250 amp alt wir extrnl regulator daul runs of xs power xpflex 0 gauge big 3 raptor 0 gauge power/ground wire full run suriken 45 amp hour x3 shriken bt-120 batts,interstate 1100CA semi batt scytek galaxy 2way alarm still upgradeing!

CJ18 Posted December 11, 2011 Report Share Posted December 11, 2011 All of mine have always reached full power at about 2000-2500rpm. Does your voltage fluctuate while at idle or does it hold solid at 14.5? Quote Link to comment Share on other sites More sharing options...

Thanks david, we´ll see what happens, we spoke about this like a month ago and i we both knew there was something weird going on, but damn, i didn´t expect such a large voltage drop using that "proper" electrical with barely 1600 watts :S Quote I´m the SPL Gains topic creator!! wanna get louder?? check this: SPL Gains.

siccostyle Posted December 11, 2011 Report Share Posted December 11, 2011 Yeah I didn't realize that it was that bad of a voltage drop either. With the amount of power that your using you should be rock solid I would think. Hopefully its just a faulty alt which can happen with a big company like Mechman. Not every alt is going to be perfect and if you got a bad one I would think that Mechman would take care of you. I have never used there products myself but I have heard good things about their customer service. Good luck homie I hope things get straightened out for you.

fecupe2001 Posted December 11, 2011 Author Report Share Posted December 11, 2011 Hey guys, some news over here, i burped the car using a single DD m2a (1600 watts amplifier) wired at 0.5 ohms and got this results: Idle: 14.6 v dropping to 11.1v 3K RPM: 14.7v dropping to 11.5v 5K RPM: 14.8v dropping to 11.8v Said that, i checked all my wires and connections and found something that might cause any problems, but i prefer to ask you guys first since you know much more than myself about electricals, i´m not afraid to say that i´m good at few things and a noob on some other, my wire from the alternator to the positive on the battery it´s a 0 gauge, when we built the car we used an ANL 200 amps fuse on that line, few months later i changed the alternator and i completly forgot i had a 200 amps fuse on that line, said that, do you guys think that´s what it´s causing the problem? maybe the alternator output is getting "chocked" because i´m using that small fuse? once again, i didn´t remember i was using that fuse in there and i have no clue if a 200 amps fuse is cutting my alternator´s output, i dunno much about electricals lol, any inputs????

extremeauto Posted December 11, 2011 Report Share Posted December 11, 2011 the smaller fuse would restrict it but i dont think that is the issue...change it and see and have u checked the alt postive wire yet? do u have a voltage reglater?is it turned up? ur getting voltage drop like the alt is barely even sending out put..
