At what RPM do/can these actually achieve the 130A? That is a A LOT of juice.
I recently bought the Hitachi alternator from Patrolapart. My old one (original 16yo unit) began acting and sounding funny so I acted before it leaves me stranded.
After a cold start ,battery taking a hit from starter motor/glow plugs, I found the new unit pushing 50A-ish at around 2000rpm. As the revs go up from there, the results are diminishing.
Point being, unless you're winching/revving the up, is there much usable benefit in these high output units for just charging dual battery systems etc????
A more important thing I noticed when I changed over my alternator is the cable from the alternator to the battery is absolutely s#ithouse. Old, annealed. No way in hell the diameter of it can push 100A IMO. Especially with the age of these motors. You'll really want to look at upgrading this, especially if you're going high output route.
I got some proper cable and lugs ready to go in mine.
