If you’ve been dealing with rough idling, hard starts, or weak spark on your vintage Ford tractor, the problem might be a failed ignition coil resistor. This little component sits between your ignition switch and coil, reducing voltage to protect the coil from burning out during normal operation. When it fails, your tractor can develop all sorts of ignition troubles that’ll have you scratching your head.
What You’re Getting
- Proper resistance value designed specifically for early Ford tractors
- Direct replacement that restores factory ignition performance
- Quality construction that handles the heat and vibration of tractor operation
- Essential component for maintaining proper coil voltage and spark timing
Built for Real Farm Work
This resistor is designed for Ford 9N, 2N, and early 8N tractors (before serial number 263843). These are the workhorses that built American agriculture—utility tractors that spent their days plowing fields, cultivating crops, and handling every farm chore you could throw at them. Whether your tractor’s running a bush hog, pulling a disk, or powering a PTO-driven implement, reliable ignition is what keeps you working.
Made to Last
Farm tractors generate a lot of heat and vibration, and electrical components take the brunt of it. This resistor is built to handle those tough conditions while maintaining the precise resistance needed for proper ignition timing. It’s manufactured to the same specifications as the original Ford part, so you know it’ll perform like it should.
Good to Know
This is the resistor only—it doesn’t include the mounting block that bolts to the tractor. If your mounting hardware is cracked or corroded, you’ll need to replace that separately. The resistor wires directly into your ignition circuit, typically between the ignition switch and the positive terminal on your coil. Make sure your ignition is off before making any connections.
