Jeff, I don't know how to advise you from here if you have it wired per Bob's diagram. As far as testing the ammeter I think you could attach a light (a fan motor or a cigarette lighter would be better) or any 12 volt item which will draw current to one side and a feed from the battery to the other side and see what kind of deflection you get in the pointer when powering up the 12 volt item. You will also have to ground whatever you are trying to power up to the same ground plane to which the battery is grounded or directly to negative post on the battery. You can do this on or off the tractor as long as you can connect the ammeter in the circuit. I would think you should unhook the other leads to the ammeter when doing this test as you just want to see if current is being measured through the ammeter. This electrical trouble shooting is not my speciality in great detail but I do have somewhat of a working knowledge and have been able to survive. I would also put in that 10 ohm - 10 watt resistor I keep talking about as that should be enough draw to excite or start your alternator into a charging mode. I was told the resistor needed to be soldered to the wires for the best connection. Was very easy to do and then go back and install a light along with the resistor once you get this all straightened out if you like the light. Those resistors are really very cheap at Radio Shack. I have only done this conversion once and then with the Hitachi 14231 alternator. I take it you are using one of those older 10SI Delcos and not something which might have an internal diode which would cause problems with what you are trying to do? You should have had a voltage regulator in conjunction with the generator and that should be totaly disconnected out of the conversion as the alternator should have an internal regulator. Send me an email to russell@wavecomputers.net
if you feel you need Bob's email address to get this completed. We all want you to succeed in this endeavor and will help in any way we can. By the way where are you locatedin this great conuntry? Good luck and hang in there and let us know how this progresses, Hal
