[AT] Electronic tach for Case?

[Mike Sloane]

The old Prestolite generator in my Case 430CK is marginal, and my local 
auto electric guy says that he may not be able to get repair parts for 
it. I would happily change the system over to an alternator, but there 
is one small issue: the mechanical tachometer is driven off the back of 
the generator using a little gearbox, and I hate to lose the ability to 
read engine speed. So my question is: does anyone have a source of an 
electronic tach that reads in the 0-2000 rpm range. I can easily find 
unit that read 0-6000, but that really isn't much use in a tractor.

I have seen ads for alternators with tach drives, but they are a lot 
more money than I am willing to spend (and there is no assurance that it 
would match up to the Case drive cable) - I usually just buy a rebuilt 
small alternator from the local auto parts store.
