evermaxx Posted June 25, 2014 Report Posted June 25, 2014 So, this morning i started my car and my VCM was reading 12.9.. Coudlnt get it to go any higher with the VCM, so I drove around the block still nothing. Around lunch time I tried again, this time it was at 12.7 when at idle. Drove off the street and it jumped to 13.3, then 13.7, then 14.6 (where it is set for hot) and then to 15.2 couple times.. it would jump to 14.x then down to 13.x then back up and so on and so on. What can be the problem? When I try to adjust my VCM it wont do anything. I have a video of it if anyone wants to see it.

Trey_Dog650 Posted June 25, 2014 Report Posted June 25, 2014 I would say it's the vcm as that should control the voltage no? 13 Kia Forte Build! 07 Hyundai Accent Build ***Super Seller*** N8ball2013 And then he gets to say ok all you guys were right. im sorry for being a dummy poo poo head.
walwalka Posted June 25, 2014 Report Posted June 25, 2014 I would get a meter out and check the voltage at the alternator stud while running. 2010 Honda Civic LX / Deck: Kenwood DDX371 / Front Highs: Crescendo RTS-1 / Front Mids: Silver Flute 6.5's / 4 channel: DC Audio 90.4 / Sub: Fi 15in SP4v2 / Sub amp: Taramps HD 5000 / Power wire: Knukonceptz OFC 1/0 / Deadener: Audio Technix 60 mil / Batteries: XS Power D5100R / Rear bank: TBD / Alternator: Singer 240a hairpin

Bump4life Posted June 25, 2014 Report Posted June 25, 2014 the vcm controls the alt. alt wont turn on without the vcm in. the vcm does not control the alt. the alt will turn on still without vcm plugged in. all the vcm does is trick the internal regulator to put out more voltage by adjusting sense wire. I had just turned my vcm in on warranty because whenever Iturned my vcm on, it would cause alt to turn off. sounds like a faulty unit. i switched to external regulation instead of the xs vcm adn have never looked back. i had too many issues with the vcm including the car starting at 16.2 plus in the winter and shutting my car off. the vcm is a cool idea but in my opinion a bad way to adjust voltage for a few reasons mainly being temperature.

evermaxx Posted June 25, 2014 Author Report Posted June 25, 2014 well, singer told me when I returned the alt (due to shipping issues, something for broke in it) he said the alt wont turn on without the vcm being plugged in. hes shipping me a new one, should be here by tomorrow because i ordered a red, but xs sent him all blue. hopefully that works Team Subsonic Lows Get your garbage EMF products of my amp bitch Man....it makes a nice work bench
