808faka Posted May 31, 2014 Report Share Posted May 31, 2014 sup guys need some help. im running 3 mechman 340s all externally regulated by the blue boxes that mechman sells, with 2 being designated for charging at 16v. the two that im using for 16v have their own blue box regulator. and my 12v that runs the car has its own. now for the problem. i cant get the 16v alts to regulate properly. with my voltage control knob i have it all the way turned down, and my 16v battery bank sits around 17v flat with the truck running. so i turn the knob up slowly and keep checking to see if theres any change in the battery bank. theres no change whatsoever for the first few small turns. so i turn just a little more and then it goes straight past 18 and into the 19s. ive emailed mechman twice in 2 weeks with no response and both their numbers aren't working for some reason. so i figured ill just run my amps at 17v till i get a hold of mechman to see whats going on. so i plug in my sundown ns1 and two 125.4s today for the first time ever on 16v. both are fine when key is turned to just before the start position, everything is sitting around 16.7 to 16.9 and all the speakers are playing fine. so i start the truck up and notice the belt squeel is louder then usual and not going away with a little rev of the engine that usually takes care of it. i immediately check the voltage on my ns1 and it was going anywhere from 18.5 all the way to 20v with just a small push on the gas pedal, so i turn it off right away. WTF is going on with my shit?? i checked my regulator knob and its still turned ALL the way down. yesterday before i plugged in my amps the battery bank was low 17s with the truck running and i could give it a full on rev and it wouldnt budge 0.1 on the meter. today i plug in the 3 amps with my knob still all the way down, and boom 19v, 20v here i come. i thought maybe the regulator box took a shit on me maybe but it still reads 12v when truck is on so.... anybody got any ideas here? i could use some help. sorry for the long post. thanks!!

808faka Posted June 1, 2014 Author Report Share Posted June 1, 2014 they rest anywhere from 16.7 to 17.0 depending when last charged them. the bank consists of 6 xs power xp1000s which are about 2 to 3 months old and never had a load on them before. always threw my charger on them and topped off the bank every 2 to 3 weeks.

808faka Posted June 1, 2014 Author Report Share Posted June 1, 2014 the times that i was trying to set the voltage with the adjustable knob and it didnt budge, i thought maybe the alts werent even on and putting out power because with the car running it would still be about 17v flat. but then they did come on for sure because it ended up moving waaaayyy past which i need it to be. into mid 19s and close to 20v with only a 1k rev of the engine.

truthsayer Posted June 1, 2014 Report Share Posted June 1, 2014 From what you are describing sounds like your voltage control module. truthsayer Link to comment Share on other sites More sharing options...
808faka Posted June 1, 2014 Author Report Share Posted June 1, 2014 that crossed my mind as well. it still reads 12v+ though when my truck is on, would that even matter? trying to think of how i could test to see if it still works. Link to comment Share on other sites More sharing options...
808faka Posted June 1, 2014 Author Report Share Posted June 1, 2014 maybe switch the field wires of the 16v box over to my 12v box which regulates my front 12v battery just fine. see if it still goes way up Link to comment Share on other sites More sharing options...

808faka Posted June 2, 2014 Author Report Share Posted June 2, 2014 i ordered a different external regulator and am gonna try it. since MECHMAN cant return one fucking email in 2 weeks. ill keep everyone updated, maybe this one will actually work properly on multiple alts, not like these shitty blue ones that give nothing but hassle.
