CJ18 Posted October 25, 2010 Report Share Posted October 25, 2010 Nathan, Can I buy a VCM for dual alts and only use 1 plug until I get my second alt in? I am bringing the truck up to Knoxville to Mechman to have a triple kit built next month but I would like to have better control of my dual alt until then so I dont set my charge voltage too high.

AMI CUSTOMS Posted October 25, 2010 Report Share Posted October 25, 2010 If you are running off the just the regulator on the alt your voltage won't be too high. I have seen personally and heard of few people having issues with the VCM running multiple alts, I have seen in my own testing it controls two alts perfectly but three and four or more, it won't let the voltage come down. I have a few theory's but I will see what XS power has to say since they make the thing.

AMI CUSTOMS Posted October 25, 2010 Report Share Posted October 25, 2010 And I believe XS will tell you it is an all or none setup. But you can get a main harness for multiple alts and then just get the additional plugs later for that multi harness later, they just daisy chain into each other with one wire, the "sense" wire.

uhoh_45 Posted October 25, 2010 Report Share Posted October 25, 2010 It won;t work with our alternator, but if you need higher voltage, we have a plug in module similar to an MLA, that is adjustable from 13.5 to 19.5 volts. mechman told me this about the vcm and there alts Quote R.I.P!

CJ18 Posted October 25, 2010 Author Report Share Posted October 25, 2010 I already have the adjustable voltage mod from mechman. I need to fine tune it just right to 14.9, but i would like to have push button control in the cab. Quote Link to comment Share on other sites More sharing options...

Nathan @ XSpower Posted October 25, 2010 Report Share Posted October 25, 2010 As long as it is GM style alt it will work fine. You can run one alt, two alts, or whatever you like. Quote Link to comment Share on other sites More sharing options...
CJ18 Posted October 26, 2010 Author Report Share Posted October 26, 2010 Is there a price difference between a VCM for 1,2, or 3 alts? And how do they hook up to the second and 3rd alts Quote Link to comment Share on other sites More sharing options...
AMI CUSTOMS Posted October 26, 2010 Report Share Posted October 26, 2010 You have to get a main harness that has the pigtail in it for the additional alts, more then one alt and then you just buy the extra harnesses for whatever amount of alts you have. Like with my quad setup, I needed one main harness and then 3 extra harness for each additional alt, the extra harnesses are like 20 bucks each I believe, I am not sure cuz xs power never send me a bill/invoice(I always have to ask for one), they just take money out of my account and then send me stuff....LOL Quote TEAM SOUNDQUBED -- TEAM SOUTH TEAM S.O.B. - Founder & Captain 3x Streetbeat World Record Holder 2017 MWSPL 1st place Mayhem & 4th Xtreme 4 2016 MWSPL 1st place Mayhem/2nd Adv 4/2nd Xtreme 4 2015 MWSPL 2nd place Mayhem & 4th Xtreme 4 2014 USACI 2nd place Streetbeat 5 - 162.6 db 2014 MWSPL 2nd place Xtreme 4 - 144.9 db 2013 USACI 1st place Streetbeat 4 - 161.9 db 2013 USACI 1st place Street Q+ - 162.8 db 2013 MWSPL 3rd Kaos2 & 4th Xtreme 4 2011 USACI 2nd place MOD 1001-2k - 160.0 db 2011 MWSPL 4th place: Adv3 - 157.8 db, Kaos2 - 150s db, Xtreme4 - 140s db 2010 ARSPL 1st place 501-750 - 160.3 db Arkansas loudest Best score to date 164.4 db - Termlab Outlaw Streetbeat 4 - 161.9 db Streetbeat 5 - 162.6 db MWSPL on Dash Legal door open (Music) - 162.5 db Sealed on dash Legal (Music) - 161.1 db - Termlab THE BLACK NASTY CURRENT BUILD & FAB The Black Nasty (6) 15 Rebuild Log 2012 (4) 15 Walled Sierra Build Log Evo X build log Facebook page The Black Nasty Link to comment Share on other sites More sharing options...
Nathan @ XSpower Posted October 26, 2010 Report Share Posted October 26, 2010 Is there a price difference between a VCM for 1,2, or 3 alts? And how do they hook up to the second and 3rd alts For One alt the VCM kit is $139 shipped. If you want it for multiple alternators, then the Controller, Main Harness, and 1 Alternator Harness is around $148 shipped. Then each extra alternator harness is $24.50 each. The main harness just hooks up to a switched power source (red wire), ground (blk wire), and alt output post (yellow wire)and then plugs into your alternator. For each additional alternator they just plug into the VCM harness and into the secondary alts. With multiple alternator applications it is a must to get the alternators hooked up and running prior to hooking up the VCM. The VCM can not power up the alternators, so the alternators must be running first. Quote Link to comment Share on other sites More sharing options...
