most probably, saying this as a mechanic, it probably drained the remaining juice of your lowlife battery, get a new one, preferably a greentop, and start the process over again. if it does happen again, (it shouldnt), take it to pro audio people, theyll help you out

does the alt have a built in regulater? some high output alt's use external regs....

sounds like the alt isnt even connected.

Did you test it with a meter after you installed it? 8.2 v dead on the side of the road doesn't tell you much.

why would he install the big 3 now? Why add more into the equation? How about he returns it to stock and see how that goes. If you still have your stock alty put it back on. Also make sure you did not crack the plug on the alt for the field wire.

i cant wait til he gets back on here after getting his car towed, so he can tell us what has transpired since then

chances are its the voltage regulator. If your lucky, its a stand alone unit, If not then it maybe inside your ecm. If it is, you will need a new ecm..($$$)
