To verify Fuse condition, i.e. The negative lead to the negative terminal and positive lead to the positive terminal. When in doubt, try to compare the reading with measurements done on a good diode of the same type. Forward biasing GS with 5V and measuring DS in forward bias should yield very low ohms. If you get readings that do not make sense, try to compare them with measurements done on a good transistor of the same type. If Multimeter reading is “Zero” or “infinite” in both attempts, it means switch is in short circuit or continuity connection is broken and you should replace it with a new one. The collector and emitter can be identified knowing the fact that the doping for the B-E junction is always much higher than for the B-C junction, therefore, the forward voltage drop will be slightly higher. If you have damaged you meter in this way, then you will need to look for burnt traces and components. The B-C junction will have a slightly less voltage drop (DMM) or a slightly lower resistance when using an analog ohmmeter. Connect the red probe to the positive side of your component, which is where the current is coming from. The meter will read one of three things,0.00, 1, or the actual resistor value. The voltage measured across the diode will be the breakdown or Zener voltage. Step by Step Procedure with Calculation & Diagrams. Dear Sir/Madam My high-fi when I plug it turns on and off , please tell me what to fix. 99% of bad MosFets will have GS, GD and DS shorted. If Multimeter reading is infinite, it means Fuse continuity may be broken or blown. HOW TO TEST.
