Ballast Resistor Not Dropping Voltage at Danelle Perez blog

Ballast Resistor Not Dropping Voltage. When cranking the coil should be getting the full battery voltage, but because of the high current through the starter the battery voltage may drop from 12 to 9 volts or less. Ballast resistor goes from ignition switch to coil +. If the voltage reading is not within the specified range, the ballast resistor may be faulty and needs to be replaced. A properly functioning ballast resistor will show a voltage. Reconnect the resistor, start the engine, and measure the voltage across the resistor with the engine running. As some models have a bypass connected with the ballast. With your battery hot take your volt meter and see what voltage you are getting at the end of the primary ignition wire (the one that goes from the switch to the coil). The main focus of this tech tip is to explain the function of the ballast resistor as well as necessary test procedures. Voltage across battery (fully charged good battery, car not running) should. The term “electric ballast” refers more broadly to any device, such as resistors, capacitors, or inductors, that helps stabilize a circuit by controlling current and voltage levels. Twist the key to start and the engine starts, release the key to run and the car stalls. Too many guys will blame the ballast. Classic ballast resistor failure goes like this. There is a simple test to diagnose the total.
