Distributor Coil for John Deere
This 12V distributor coil with external resistor is an electrical component designed to generate the high voltage needed to fire the spark plugs in compatible John Deere engines, referencing OEM cross-reference numbers AT10399 and AT14385.
Overview
This 12V distributor coil with external resistor delivers reliable ignition performance for tractors and machinery. It is built as a direct replacement for the original coil, ensuring proper spark delivery to keep your engine running smoothly. This coil is intended for use in John Deere models that accept the AT10399 or AT14385 specification.

Good To Know
Q: Do I need to keep the external resistor connected? A: Yes, the external resistor must remain in the circuit to limit current through the coil and prevent premature failure of the contact points.
Q: Will this coil work with a 6-volt system? A: No, this coil is rated for 12-volt systems only. Using it on a 6-volt system will result in weak spark and poor performance.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
