So I think if my stereo system is on, I should see some decent voltage considering I will be drawing some decent amps from the battery at the time, and the system should try to run in "CHARGE MODE" considering the amp load!!!!

NIK12937 Thanks for the posting of this! NIK12937 what kind of voltage are you seeing as far as your setup going considering you have a HO ALT. I would guess you must have some decent current draw from your charging system and battery considering you have bought a HO ALT.
