OK, my alternator is certainly part of the problem so rather
than repaire I would like to upgrade.

I searched the Vanagon archives and checked out Tom's VW
Pages:

But most upgrades are for WBX. Anyone ever upgrade an air
cooled Alternator?

Anyone have any comments on my aux battery below?

Thanks,
Chris
