Remember, precautions are first as you are working with electrical devices, which generally hazardous. How many lumens does a 400w metal halide have? Situation: I inherited 3 100W overhead fishing lights (metal halide with pulse start) and one of them died circuit doesn't have a capacitor, but has ignitor; bulb is marked with M90/E; fixture uses 120V AC, but multimeter shows 240V at the bulb base by moving parts (ballast, bulb and ignitor) to other fixtures I figured that ignitor is not working Tighten the loose connections with the help of a screwdriver. A LICENSED ELECTRICIAN SHOULD ONLY PERFORM THE STARTING VOLTAGE OF A SLIMLINE BALLAST. Remove the protective covering using a screwdriver. A lot of apprentices (and journeymen) have trouble understanding what makes HID lighting any different than regular lighting so troubleshooting them can be a. Test his plans. Set the multimeter to ohms and touch the probes to the two terminals on the ballast. Sadly, not everyone knows how to diagnose this device for faults. A diagnosis also requires you to test its resistance, and you need to have it rid of electrical current to accurately do this. Plug the ballast plug into the bulb socket to connect the HID bulb to the ballast. A typical ballast has two terminals, one marked input and the other output. The input terminal is usually connected to a power source, such as a battery, and the output terminal is connected to a load, such as a lamp. Check engine light is lit. There are two main types of ballasts: magnetic and electronic. In case of any leak, replace the ballast. There might be a loosened socket preventing the bulb from working efficiently. Now, turn the power ON as well as the circuit breaker. Turn off the switch to your fluorescent bulb, expose the ballast in its housing, and set your multimeter to the highest resistance setting. All these are represented by on the meter. Look for the blown-up fuse Also, check any blown fuse that needs a repellent. The bulb that comprises the lamp contains electrodes as well as a mixture of metal halides (salts) mercury vapor, and an inert gas to sustain the process, such as argon. Look inside the ballast for a blown fuse and replace it with an intact fuse. Disconnect or turn off all other electrical components that are on the same circuit as the lamp and then try the lamp again. Turn on the lamp and touch the ends of the tester leads to the lamp electrodes with the bulb in place, then remove the bulb and make the same test. Because the majority of the wires appear to be black and white, you can touch your multimeter probes on them. There are no metal wires inside of an HID lamp like you'd find in a standard incandescent. You can have a quality kit under 100 USD.
