According to my DESTEC schematic, and I'll trust J.J. Wheatley to have it right, there is a fusable link attached to the alternator and a 10 gage wire from the link to the fuse panel. According to my aircraft electical instructor, and everything else I've read about alternators, optimum output for charging batteries is 13.8-14.2 volts. With that being said, on my electrical battery chargers, I've seen the volt go way higher than that, after the battery is charged and not taking any more amps. I think someone is blowing smoke. But I'd check the voltage at the battery and see what the voltage is with the engine running. HTH.
