he doesn't say what his charging system is, nor does he say what voltage he is actually getting at the battery. Does he already have a split diode ? where is the sensing taken from? etc. etc. He may not need to have anything done to the alternator at all! I would like to see what the voltage at the battery terminals is. Lots of possibilities.The old split diode unit had a trait that was a pain - but in your case may be an advantage ... it caused a drop in actual voltage at the batterys by approx 0.5 - 0.7V ..... its why Sterling / Adverc and various created controllers to counter it ...
Basically the alternator was thumping out its 14.5+ V to the diode box ... the diodes caused a drop in voltage and batterys were never fully charged .... so we had a choice - fit a Sterling or other box that was battery sensed - to beat the alternator ... or alter the alternator itself.
For your setup - just the Diode box would do the job you want .... reckon you could find one cheap in a yard ... I have one not used still in my engine bay - but I'm in Latvia so not much use to you ... sorry.
