1 Wire Alternator

1-wire alternator on my H, I know a lot of people don"t like them. I"m hoping to not get into a debate on how much better a 3-wire setup is just help in troubleshooting.
It excites at very low RPMs, works fine. however after a couple of minute it stops charging. Amp Gauge goes back to 0. If I turn my lights on it will not kick back in. The belt is not super tight, is it possible that this is causing the problem as it warms up? I have not tried to start it and turn lights on while it"s charging to see if it will stay charging. Am I missing someting? all of my connections are good.
 
Yes, the belt could be slipping, or the battery could simply be "full".

Is the Ammeter wired correctly.... battery to one side and the alternator and ALL electrical loads to the other?

Watch the battery VOLTAGE at startup and after the charging tapers off. Results????
 
An alternator doing its thing will do exactly what yours is doing. Check the voltage when it is running and if it is sorth of 14 all is well.
If the lights on still results in a centered meter, it is fine, the load does not go through the amp meter to the lights, the only thing seen on the amp meter is battery charge, or discharge.
If it is not charging, and as bob indicated the belt is appropriately tight, the battery is full.
Just like charging a cell phone, the little indicator says full.
Old generators were so poorely regulated that they often charged when they should have stopped. Jim
