HAS ANYONE OUT THERE EVER CONVERTED THEIR INTERNALLY REGULATED ALTERNATOR ON THE WESTERBEKE 10TWO ENGINE FOR AN EXTERNAL REGULATOR (TO IMPROVE BATTERY CHARGING)? I AHVE A 40 AMP ALTERNATOR WITH INTERNAL REGULATOR AND AM THINKING OF ADDING AN EXTERNAL, MULTI-PHASE REGULATOR (E.G., XANTREX INCHARGE). I HEAR YOU HAVE TO DISCONNECT THE INTERNAL REGULATOR AND WIRE THE OUTPUT TO THE EXTERNAL REGULATOR. ANY THOUGHTS OR ADVICE IS APPRECIATED.
