I just wanted to throw this problem out there, because I'm at a loss...
My cub rarely starts without having to charge the battery, and at times, will run for 2 to 3 minutes, then stall. On other days, it will start, and as long as I'm using/driving it, it will run forever. I cannot get any of the lights to work, although the fuse is good. While running at idle, the ammeter reads 0 to -5, at higher rpms it reads +10 to +13. Other than what I believe to be an electrical/ignition problem, it runs very well....no smoke, dosen't miss, and has full power. On a good day, I can easily start the thing with the hand crank.

Your ammeter readings while running indicate that the system is charging. But, since you must charge the battery before starting, I'd say there is something draining the battery when it is not running. How old is the battery? The overall easiest thing would be to replace the wiring harness and re-check the grounds. Will the tractor re-start right after shutting it down? If so, does the battery sound weak?
I don't think the stalling problem is related to the charging problem.
On the lights, you need to check to see if the voltage is getting to the lights. If it is, check the grounds, check the grounds, check the grounds!

Thanks for the idea....
The battery is two years old. I bought it whenI "inherited" this tractor from the mother-in-law. I kinda thought that it might be bad as well, but given the relative age of the battery, and the fact that the lights were working one day, then not working the next time I used the tractor, I figured that it was just some sort of electrical gremlin. Your questions also make me think that it is the battery the more I mull the problem over in my dusty little mind - I ususally disconnect the ground cable (on the battery) when I am not using the tractor, so that any grounding issues can be circuvented and the tractor will start when I need it. Lately, this has not been working, and the battery is still dead...after having been disconnected.
As for the wiring harness....any thought as to where I might get one? About how much do they run? Also...what is the little box that is mounted above the generator...the metal "cap" fell off of the housing, and is now just sitting on it to keep out the rain.

fireman, The battery drainage problem could be the voltage regulator sticking also.......possibly the little square box with two coils of wire inside?

Splicer has a good point. The loose cover on the cut-out or regulator may be the problem. Since it's already loose, someone may have had problems with the regulator in the past.

Again, Thanks for the tips. It all is starting to make a little more sense to me now....if the regulator was/has been sticking, the repeated charge and discharging of the battery would have eventually taken it's toll, and killed the battery for good. I should have tested the darn thing from the get go, but having just moved here from MI, i didn't really have the room nor the time to bring all of my tools and toys here, so I had no way to test the battery, or any of the elec. sys. for that matter. Do you think that there is any chance that the regulator malfunction could have affected the generator in any way, or should it still (theoretically) be ok as long as the ammeter showed charge?

I don't think it has harmed the generator at all. It is charging as it should. It just needs to be regulated and the current drain source needs to be corrected.

Welcome to the Forum and to the Cub Family. Inherited Cubs are great. They usually have interesting histories to them and of course the family connection is pretty nice too!
BD gave you some real good advice. When it comes to electrical he da man!
As for your second question on wiring harnesses. You can go two ways, but I do not know what it would cost either way.
First, what year is your Cub?, as that will determine what harness is needed. Apparently there are 8 different harnesses available. You probably can get the wiring harness through your CaseIH Dealer, or http://www.casetractorparts.com
. You can also get them from firstname.lastname@example.org
, which is also listed under Specialty Suppliers link on the Manual Server main page. Lloyd can tell you which harness you need.

If your Generator has a metal box mounted on top of it you have a Cut out relay and a pre 1950 tractor.
Cut out relays did not go bad to often however if the cover is gone it probably has dirt in it and then they will stick and drain the battery.

, and the battery is still dead...after having been disconnected.
I would start with a new Battery the see how charging system is
working as you unhook the batt. and it is still going dead it sounds to me that the batt. is junk.
The lights how ever should still light even if the charging system is
not working as they would use the batt.
It sounds like your charging system is working as 0 -5 at low idle
is not that unusual.
If it were mine I would start with a new batt. & please don't buy the cheapest as they don't last as long. ( you get what you pay for).
Then check every connection for broken wires & contact then ck. the grounds again.
More elect. problems on these cub's are due to ground prob's than
almost anything else.
PS: don't for get the older cuds were + ground not - ground.
