How do you test a micro sensor on a flame sensor? In case of any leak, replace the ballast. Your fluorescent bulb looking like it is burnt at its extreme ends (due to dark spots) is another sign to watch out for. TMElectronic Metal Halide Ballast has a highly advanced protection system that will immediately shut down the ballast in any of the following events: open circuit (no lamps), short circuit, defective lamp, rectifying currents, partial glow discharges, lamp end-of-life (high voltages). You simply disconnect it from any power supply and use a multimeter to determine if its wiring has high resistance or not. MM is also known as the volt-ohm meter. The line voltage enters the ballast first. So, turn the breaker off at first. Supply the correct amount of voltage to the ballast. Premature ballast failure is often caused by the surrounding environment. 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.

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. Then, using your multimeter set to ohms mode, measure the resistance between the two terminals on the ballast. First, make sure that the ballast is unplugged. To measure it, set your digital multimeter to around a thousand ohms resistance setting. The color temperature of lighting produced by metal halide lamps is close to natural sunlight. Before testing, expose the ballast. Put on your latex gloves. Using one in an environment with inconsistent temperature or environmental conditions causes it to develop faults. These are called 4-tap ballasts and they operate 120/208/240/277V. The ballast itself can go bad, which causes lights to flicker or even appear to be burnt out, when in fact they arent. Remember not to get confused by the name. Most manufacturers, in the case of Metal Halide, give these HID light bulbs a life of about 20,000 hours. How many lumens does a 175 watt metal halide put out? Unless there is a fuse installed just ahead of the ballast, if the primary winding in the ballast goes bad, they almost always trip the breaker.
