Any good automotive alternator / generator rebuilder can do it for you.
I just had mine done.

"words of wisdom", if you haven't already bought it, don't buy your
regulator from someone like West Marine [we call it "Worst Marine"].
They get $275 for the good Xantrex # 2006, I bought mine "on-line" for
$172 [brand new] including shipping and tax.

Anyone out there have any experience or words of wisdom to offer on
removing the internal regulator from a small alternator like a
Hitachi
LR135-31 so as hook up an external unit that will properly charge GEL

or AGM batteries?
