|
Voltage 12 volt |
Type With internal resistor |
|
Resistance 3 ohm (primary) |
Application 12-volt ignition systems |
Features
- Built-in resistor — no external ballast required
- Suitable for 12-volt conversions and original 12V systems
- Primary resistance: 3.1-3.3 ohm
- Ready to fit
- Replacement part for points distributor systems
★ This coil is equipped with an internal resistor, which simplifies wiring and makes an external ballast resistor unnecessary.
Installation notes
Check polarity: on a negative earth battery, connect the (-) terminal of the coil to the distributor. Ensure clean and tight connections. If in doubt about your system voltage: check battery, lamps and voltage regulator — mixing 6V and 12V components can cause damage.
Compatibility
ONLY suitable for 12-volt electrical systems. DO NOT use on 6-volt or 24-volt systems. When converting from 6 to 12 volt, battery, lamps and possibly the starter must also be replaced. Never combine a 12V coil with a 6V system.
Historical context
From the mid-1950s onwards, most Willys and Jeep vehicles switched from 6 to 12 volt. This coil is a modern replacement part for those systems and for later conversions of original 6-volt vehicles.
