OK guys, I'll try to find an oem resistor. The owner of this tractor had put a jumper across the terminals of the resistor when it burned out so he could feed his critters, but the points didn't like it and eventually gave up. That's when he asked me to convert it to 12V. I've worked on the engines of these little tractors quite a bit, but never did a 12V conversion on one.
I guess I should ask; What is the voltage I should be shoot'n for when measured at the terminal on top the coil? It's my understanding that the original 6 volt system was reduced to near 4 volts at the points by the oem resistor. Would that be a bit too much to expect on a 12 volt system.
I found some 12 volt conversion information on the 'net' that showed a second resistor in series with the oem resistor but it didn't say whether the coil was still 6V or had been changed to 12V.
