Case 220 charging system

My battery seems to lose a lot of charge in a week or so, less now that the weather is colder. I've replaced the battery and also had the starter rebuilt since it seemed to have " spots " where it turned the engine and others where it didn't. I"m still not satisfied with it. Seems like the armature isn't round. Where is the charging system in this ? The charging gauge doesn't work and I'm trying to find out how to get at it. Any thoughts on this ? If I start it and yank the negative off the battery and it still runs, is the charge sufficent to charge the battery or do I need to test it ? I'll need this for the winter moving logs to my OWB and jumping it consistently is a pain in the butt.

Does this case have the large starter/gen? If so, there is a regulator in harness, maybe up by the battery box?? I have a 210 and just going by that lay-out. Have to remove the battery and even better the whole tray to get at items in dash area easier. One way to test output is with voltmeter right on batt terms. Non running should be 12 or 12.4 or so and when started, should read 13.5 to 14 volts when running, IF the regulator and gen are working. I wouldn't think the tractor would run at all with batt cable off. Thinking this is a battery ignition? Runs till Battery is low or dead, then dies out. Maybe you have a key switch issure or wire bare touching somewhere and draining system.
 
Do you have a correct operator"s manual? That"s where you"ll find a proper wiring diagram. The 220 was made for twenty-years. When you don"t include a serial number, it"s a guessing game.
 
Which engine do you have? You may have an armature for a coil and it won't require battery voltage. Briggs and Kohler both used Delco starter/generators for starting and charging their batteries. Here's what Kohler used on some of their engines. Hal

If you have a gear type starter you may have a stator that produces AC voltage and a rectifier
to convert the AC to Dc volts. Kohler used that
on a JD 140 I had back in the late 1970's. With the engine running at 3/4 throttle your 2 outside terminals on the rectifier should show 30 ac volts when using a volt meter set on Ac volts. If there's very low AC voltage or no voltage your stator needs replacing. If you have 30 ac volts the rectifier is defective. Hal
