READER: I have a question about changing to an electronic ignition. I have an International 2424 gas tractor. It runs well and has low hours. I don't use it a lot, and when it's not used for a long time, it won't start. After cleaning the points, I have no problem until it's not used for a while. It uses a 6-volt coil but is a 12-volt system. I think it has some sort of wire resistor that goes between the resistor and the coil. Do you think it's worth the money to convert to the electronic ignition?

STEVE: Conventional systems with points (see inset photo, left) don't seem to last as long as they once did for sure. I believe the material used has changed, and the points want to oxidize, losing contact. Most farmers have enjoyed the change from conventional points and condenser to the electronic ignition (see inset photo, right), which eliminates a lot of problems.

However, the most common complaint I hear about changing to electronic is that the tractor is hard to start or will not start. But, this problem is usually caused from not buying the suggested coil that is usually available with the electronic system. The recommended coil puts out many more volts, and it usually is an internal resistance coil, which eliminates a resistor between the switch and coil. I think the switch to electronic would be great for you, but be sure and buy the suggested coil available for the electronic ignition kit.
