Leece Neville update. Sent alternator out for rebuild and upgrade . Now have a 220 amp alternator,  basically my front housing adapted to a new unit . It has two positive posts whereas the old 3425 J had one . I'm wondering if this is for a Duvac system.  Not familiar with Duvac,  presume it isolates the batteries so the chassis and house batteries can be charged while traveling. I want to be sure this alternator is going to work before bolting it back on .
Thanks,  Chris.
