Ford ballast resistor location

On a FORD made in the 1960's and 70's the STOCK Coil Feed Wire (red with blue or black stripe) IS A BALLAST RESISTOR WIRE, no extra parts are necessary, hook directly to coil +. If your Coil requires a full 12V {ALL COILS that I've seen say State Voltage Requirements on the coil it's self} Then you must BYPASS the OEM Ford Coil+ wire.

May 30, 2014 · Let's Install a Ballast Coil on the 1974 MGB-GT! (Setting Up the Ballast Wiring) - Part 1 - Duration: 5:36. The Great British Car Restoration 9,429 views Sep 16, 2003 · +12 volts from the old ignition feed wire, that goes from one side of the resistor and also to pertronix red wire. other side of the ballast res. goes to + terminal on coil. Black wire from pertronix to - side of coil. Wire from the points, obviously has been eliminated. Got that straight outta the pertronix instructions, also follows common sense.

The reason you did not see the resistor originally, is the factory one from Ford, was a resistance wire in the wiring harness, not a ballast, like you are about to install. So you can pick your own mounting place. No right/wrong. Actually, all Ford products that use points and condenser require the resistance wire to cut voltage to the coil so that the points don't wear out incredibly fast. Whether you have a tach or not, the resistor wire is still needed. Some aftermarket ignition systems like a reduced voltage at the coil; others require a full 12V. Rated at 0.8 Ohms of resistance this MSD Ballast Resistor includes the needed wire for a simple installation.Application. This 0.8 Ohm MSD Ballast Resistor is designed for 1979 to 1985 Mustang that are upgrading to a MSD Ignition Coil. Sep 21, 2004 · The ballast is a resistive wire. S216 is a junction point under the dash, close to the switch. The wire colors are also indicated on the diagram. From the start switch contact you have two wires, Brown with pink stripe and Red with light green stripe. The ballast resistor on my Ford 800 broke and I am wondering if anyone knows what resistance I need. The tractor is wired for 12 volts and the coil has between 1 and 2 ohms resistance.

resistor wire, ignition coil, replacement, original is buried inside under dash loom, customer must splice into existing loom at firewall connector and run to ignition switch to the red w/ green wire out the back of the switch, dupli With an electronic ignition distributor, you don't need any type of resistance wire or ballast resistor.This may be why your encountering running problems.The resistor wire/ ballast are there in a point type ignition to reduce the voltage to the points in order to keep them from wearing out prematurely.
