Purplehaze Posted May 13, 2011 Report Share Posted May 13, 2011 well that sucks... so how exactly does the PCM determine what voltage to output..? I'm guessing it is a preset number based on what the sense wire tells it. My question is this, if there is no way to manipulate these kind of systems, how does an MLA work? Does it basically bypass the PCM?

la negra Posted May 13, 2011 Report Share Posted May 13, 2011 pm sent to ami customs and 97ssblazer So, did you try it? If so, which one, brown or grey? I'm guessing if you did, you're not liking the results? i tired the brown wire but nothing happened so I took it off Now reading what could of happened im happy I did Link to comment Share on other sites More sharing options...
la negra Posted May 13, 2011 Report Share Posted May 13, 2011 For all others who attempt to try this, yes, putting a diode or resistor on your sense line will raise voltage, but don't do it unless you ABSOLUTELY know what your doing.. On EVERY GM made from '86 up, the S wire is the sense wire if so equipped, some vehicles however dont run an external sensing regulator and only have the LF terminals (which is different than the 2 pin RVC altogether).. Don't ever start putting resistors/diodes on any L or F or P terminals.. On the L wire, you can overload the lamp driver and smoke the regulator, on the F wire, your going to raise/drop the field monitor voltage to the PCM and your vehicle will not like you, and unless you really want to start blowing diodes up, by all means don't put a diode on the P terminal unless you want to directly short your diodes out. P=phase, it's a hard wired pinout to the stator, and has a constant ~7.36v DC output.. So what do u advice us to do if we have a Gm ad244 alt with only 2 wires brown and gray. Can we add a wire to the S terminal of the alt ? Link to comment Share on other sites More sharing options...
bdubii Posted May 17, 2011 Report Share Posted May 17, 2011 The diodes I ordered finally showed up and I installed them and gained 1.45 volts. My truck now charges at 15.45 volts when it's about 80 degrees with the radio, headlights, and ac off. Thanks to loudcivic for finding out which wire was the sense wire for me and also to the op.

knowledge Posted May 21, 2011 Report Share Posted May 21, 2011 x2 i need this bad voltage drop and all is crazy low. i have a 2003 honda crv with 12k and need help, if anyone can help me on it pm me thanks REFF'SMy linkEBAYhttp://feedback.ebay...ck&myworld=trueI love car audio so much because I will never be done.
