Description
If you’re upgrading your classic Ford tractor from the old 6-volt generator system to a modern 12-volt alternator, you’ll need this little resistor to keep your ignition coil happy. This 0.6 ohm resistor is used in alternator conversion kits and makes sure your coil gets the right amount of power to fire those plugs properly. Without it, you could burn out your coil or get poor spark performance.
What You’re Getting
- Precise 0.6 ohm resistance designed for Ford ignition systems
- Essential component for 6V to 12V alternator conversions
- Protects your ignition coil from overvoltage damage
- Prevents weak spark or coil burnout issues
Built for Classic Ford Work
This resistor is made specifically for Ford 2N, 8N, and 9N tractors that are being upgraded with alternator conversion kits. These tough little workhorses from the 1940s and 1950s are still earning their keep on farms today, but their original 6-volt electrical systems can be temperamental. Converting to 12-volt alternator charging gives you more reliable starting and better electrical performance for work lights and accessories.
Made to Last
This TISCO-brand resistor is built to handle the heat and vibration that comes with tractor work. It’s designed to dissipate the electrical load properly while maintaining consistent resistance over years of operation. Quality construction means you won’t be dealing with electrical gremlins down the road.
Installation Notes
This resistor mounts in-line between your ignition switch and coil as part of the alternator conversion. Most conversion kits include wiring diagrams showing exactly where it goes. The old 6-volt coil needs this resistance to work properly with 12-volt power – skip this little part and you’ll likely fry your coil. Double-check your conversion kit instructions to make sure you’ve got all the pieces before starting the job.
