Troubleshooting Hid Ballast

To troubleshoot your HID ballast, you will need:

  • A screwdriver and a multimeter (reading in volts)
  • Replacement parts (if needed)
  • Ballast tester (if available)
  • Time adjustment tool (optional)
  • Cleaning supplies such as rubbing alcohol, lint-free rags, and cotton swabs
  • Gloves (if cleaning with any cleaner)

Procedure: How to Troubleshoot Hid Ballast

Step 1: Clean Your Ballast

The first thing you should do is clean your ballast, and it’s surrounding area. Remove any dirt or

Clean Ballast and It's Surrounding Area

grime present, including inside the ballast and in the connector wires. Next, use a cotton swab dipped in rubbing alcohol to wipe away dirt and grime from the connections and wires.

If you find large amounts of dirt or grime, you might want to use a soft bristle brush (toothbrush) and some water mixed with dish soap. Be sure to dry all parts completely before proceeding.

Step 2: Check Wires for Any Signs of Corrosion 

Next, check the wires for any signs of corrosion (any discoloration such as green or black) or fraying (exposed wire). If you find signs of either, cut back about an inch from the spot where it is visible and discard any remaining wire. 

After doing this, strip the end of the new wire (using a knife) to expose bare metal. Then twist together one exposed end with a piece of electrical tape, making sure there are no loose wires.

Step 3: Turn Off the Ballast

Turn off your car and remove the key. Next, place your multimeter in volts (DC) mode with a voltage range of 20V-50V, and set to read direct current (DC). The lowest setting that will register is usually 2 or 3 volts; this is not zero, but you can check zero on the multimeter display by touching it to a grounded metal surface.

Step 4: Turn On your Multimeter

Turn on your car and any accessory lights, such as headlights or interior lights. Make sure all accessories are turned off before proceeding with this step. Next, touch one end of your voltage probe to the battery’s positive terminal and touch the other end of your probe to each wire on the connector. If you get a reading, usually 12 volts, you have a positive voltage running through that connection.

Step 5: Check the Voltage at Each Connection

Next, check the voltage at each connection, including the ballast’s plug, wires connected to the ground, and any other connectors you can test. Remember to check your negative power wire first if you have a positive voltage test.

Next, check your positive power wire (12 volts) for continuity with the ballast’s plug by touching

Check Your Positive Power Wire

one probe to the positive wire and touching the other probe to each pin in the connector. Again, the multimeter should read a closed circuit because there is no power running through any of the pins.

Step 6: Test for Resistance at Each Connection

Finally, test resistance (ohms) between your positive power wire and each ground connection, including the battery’s negative terminal. If you can get an accurate reading, ohms should be between 500-900 for this step. If you do not have a ballast tester, the only way to test this is by turning on your car and testing voltage at each connection to ensure zero power goes to that connector.

If you determine that the problem lies with a particular ground wire, make sure it is clean and well-attached to the chassis and not frayed or corroded. If you cannot get your multimeter to read the correct voltage, then it might be a good idea to go ahead and replace any wires that appear frayed or corroded.

Safety Measures and Warnings

1. Always turn off your car before testing any connections.

2. Be mindful of the voltage put through the positive wires when testing with your multimeter.

3. If you cannot get a reading, check the voltage on both sides of the fuse box first.

4. Disconnect the battery terminal if necessary.

5. Do not touch anything live or energized unless necessary (such as when testing for voltage).

6. If you feel an unpleasant tingle when touching anything, immediately stop and leave the vehicle alone. The source of electricity should be removed by a professional before beginning your work or driving your car.

7. Do not cut any wires unless necessary.

8. Do not attempt to short circuit anything, as you could risk damaging your car or yourself.
