I have 2 batteries up front stock and one 2400 in the real. I need to see if it drops off to 15.4. I know when I first checked it was about 10min after I turned the truck on. So it might of dropped off to 15.4.What alt do you have brand HO or stock?
Module should have no affect on your AC which is on a totally different circuit. So no answer for that. If your seeing 15.8v its gettin a low charge signal from your car/batteries. 15,8 @ cold start is ok it should back down to 15,4 or so when hot. 15,8 for comp would be fine, 4+ battery banks need the extra volts and can dissipate it .
MLA
I have the regular one. Trace what wires? The MLA is rather simple one cord coming out has a pig tail on it to plug the stock alt plug in to and one that goes back in to the alt, then just a wire that goes to the positive of the alt.I would trace the wires and see where they lead. GL Let us know I hope mine is good. Do you have the regular one or the Pro?
Old thread and common (most likely) question. Where do you get these? Seeing how the 15.8V kills AC, I am assuming 14.x wouldn't wreck havoc on my important systems? I need so much more than 13V //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gifwow I was just about to order one.
