Install Ballast Resistor To Ignition System Step 4: install ballast resistor. set the ballast resistor up to the firewall and screw the clamps in place. step 5: connect wires to positive. strip the end of the positive wire from the ignition, and connect it to the positive end of the resistor. from the other terminal on the resistor a wire goes to the positive on the coil. This is to be safe from any possible electrical discharge. step 3: remove the positive lead to the ignition coil. the ballast resistor should have its own secondary wire with a round or u shaped wire terminal end connected to the positive coil lead stud. step 4: remove the wires from the ballast resistor. one comes from the ignition switch.
Install Ballast Resistor To Ignition System A ballast resistor is used in a device to compensate for changes and secure the other components of a network. when the current flowing through the resistor increase, the temperature also increases. and due to the temperature rise, the resistance also increases. therefore, an increase in resistance limits the current flowing through the network. 4. attach the ballast resistor to the firewall using the clamps. 5. connect the positive wire from the ignition to the positive end of the resistor. 6. connect the other terminal of the resistor to the positive terminal of the coil. 7. install the condenser, located with the ballast resistor on the firewall. 8. The typical automotive ignition system prior to 1974 consisted of a coil and ballast resistor, with breaker points to interrupt the current flow when a spark was needed. the job of the ballast resistor was to inhibit current to a level that would not overheat the coil. this simple system is easy for even the novice mechanic to wire. Location of ignition coil ballast resistor. be sure to check the coil voltage with the points closed or with a jumper wire from the coil to ground. if the points are open you will measure 12 volts with or without a ballast or resistor wire. no current flow means no voltage drop. if the points are arcing a lot, you probably don't have a.
