Lbox88 Posted April 18, 2012 Report Share Posted April 18, 2012 So far, not that I know of. As soon as I see it start dropping, I turn my lights on. Quote UBL | Build Log Link to comment Share on other sites More sharing options...
Guest DC Power Rob Posted April 18, 2012 Report Share Posted April 18, 2012 On some vehicles, turning on the lights will help and get the PCM to raise voltage, some it wont.. I just have to ask though, first off, did you run wire from the either the alternator or front junction block to the batteries in the trunk?? If not, start there. Yes, it's a PITA to run through the car, but, if you cant get power from point A to point B, the alternator upgrade is kind of a moot point. If you did do that, then your only solution is an MLA module. We've done them many, many MANY times, and it's still the only reliable solution to bypass it and if you really want higher voltage, I would start there.. We are working on a solution for the low voltage caused by the RVC system, but it's a ways away yet. Unfortunately, GM did this one good, and it's NOT easy to work around by ANY means.. Just remember, low "voltage" doesnt equate to low "output". You still almost doubled your available current, it's just at a voltage lower than you, me, and everyone wants to see..

ToddB Posted April 18, 2012 Author Report Share Posted April 18, 2012 Yes I ran a extra 0 gauge from alternator to the batterys. I did call DC yesterday. Thanks guys. Quote Link to comment Share on other sites More sharing options...
