Mike,First thing you want to do is a load test on the battery your using. This will identify whether the battery is good to start off with. When you pull a "draw" with a good draw tester, the needle shouldn't drop much, or at all if any. If it drops way down, it's battery time. Now, on 1 wire alternators, most 1 wires need 1000-1200 rpm's to excite the regulator for charging to start. Once the charging rate starts, it will charge till you shut off the tractor. (Charging rate should be between 13.9-14.5 14.2 is ideal)If you're using a voltmeter, a voltmeter hooks up differently than the OEM Ammeter. On the back of your voltmeter: the plus (+) to the battery or starter motor, and the ground (-) to the battery ground anchor bolt or battery grounding post itself. That's it! Also, it couldn't hurt to install an auxilary ground wire off the back of the alternator just to make sure the alternator has a good ground to the engine block. If you're using a 10SI style Delco Alternator, there is a threaded hole on the back to attach a ground wire. Good Luck, & have fun! Steve B.
