Running a old Motorola alternator with a regulater  on backs told this thing is no longer available so  I bought  a 1 one wire power master great piece but it's to big  for my plate mount in front has anyone out there use a mini alt and if so , what kind I don't want to rebuild the Motorola  as I'm told it produces 37 amps and I got a stereo with subs and a msd ignition and so on and need more power thanks
