Generator Battery Charging

[Mark Johnson]

I have an 88 PT 40 WB and the generator battery only charges from the
engine alternators. Shore power and generator power don't do it unles
I hold the "link batteries" switch. Does anybody know if one of the
two chargers in the back is supposed to take care of the generator
battery? Could one of the two be inoperative? Or is there a third
charger somewhare dedicated to the generator battery?
