One useful option is to get an adapter bracket from me that allows most
common 90 Amp Bosch alternators ...like the ones fitted to every waterboxer
vanagon, 83 to 91 , to be bolted in place on your stock diesel vangon
engine.
three advantages -
- very common alternator.
- more amperage charging
- you get rid of the molded plastic alternator wiring plug that DV's use,
that wear out and can't be gotten anymore easily, or at all. I have maybe
two good used ones, but it's a old dedicated part that you eliminate going
to the more common 90 amp alt.
So that means some minor wiring modification ........just standard crimp
type wire connectors.
and swapping over a DV alternator pulley onto the 90 Amp alternator. There
may be a slight spacer washer or two needed for belt alignment ..and I
recommend tightening the alternator pulley nut with an impact gun only.
but that's one solution.
I also have a few used stock DV 65 amp DV alternators if anyone needs one.
