Two Dead ones... NAA 8N... need help!

The 8N: This may be the coil.. but! After a 5 to 10 minutes of running, it dies. I'm going to try the coil and the switch, but I already know I have a charging problem and had it a week before this other problem. There is not enough battery juice to turn the starter. I am not sure if it is the battery, regulator or generator and if it is related to the problem of dying. After I try the coil and the switch, how can I isolate what the charging problem is? This is an original 6V system.

The NAA: After running fine for months... I was disking the pasture and it began to lose power. It got real weak, sputtered and then died. It would restart and run for about 2 or 3 minutes, sputter and die. I swapped the carb and the coil from my other NAA... no help. I did get it restarted enough to get it back to the barn. It ran very weak... only in first gear. Now it is permanently dead. The voltage on the coil reads a little over 10Vs, but seems to have plenty of cranking power. This is a 12V system with a generator and regulator. Could it be an electrical problem? It is getting gas and, as I said, I even tried a different carb.

Sorry for being long winded.... Please help if you can!

Thanks in advance!

The 8N turned out to be a cracked battery cable terminal and a bad battery. Replaced the terminal and battery. Works Great!

The NAA... not so done yet. I discovered the points were fried. I Replaced the dist. cap, rotor, points and condenser. Still no spark. I took a spark plug and hooked it right to the coil primary wire... NO SPARK! I ran the same test on my other 8N with a 12V system... tons of sparks. The coil reads 10V on the input and output... same as the 8N. Do you think the coil is bad? This was a 6V coil on a 12V system. The coil actual says "No Resistor Required" and there is none! :-)

Thanks to all and to Claus for the great web site!
