[AT] Problem with the Case 430CK generator

[charlie hill]

Mike put it back together, charge the battery up hot and run it.   If you 
don't run any lights it'll run all day then recharge the battery at night. 
That'll get you buy until you figure something out.   I thought I sent you a 
link to a tach drive adapter that fits on most any alternator.  I don't have 
the link now.

Subject: [AT] Problem with the Case 430CK generator

The Prestolite 12 volt generator on the Case 430CK (gas) tractor stopped
making electricity, so I took it down to the local auto electric place.
He told me today (and showed me) that the field coils are open, and he
is unable to locate replacements.

Normally I would say "the heck with the generator" and install a
rebuilt/junkyard GM one-wire alternator. There are two problems with
that approach: 1. the mechanical tachometer is driven from a gearbox on
the back of the generator, and 2. Case used an oddball mounting for the
generator that will make mounting an alternator a little tricky. (The
cast generator bracket bolts to the top of the hydraulic pump body!) The
guy at the shop *thought* that he remembered that GM made an alternator
with a tach drive on the back, but he called around and couldn't find
one. I can live without the mechanical tach, if that is the only
alternative.

So my question is: does anybody have any suggestions? A Google search
turned up nothing useful, and the tractor is needed for moving some
large hunks of tree that I had cut down last week.
