what is the best method to check if capacitor short ? until today i've examine a lot of pics that ask to check if capacitor is short , im doing it right remove him and measure by ,multimeter or just look for any bad signs on him , like color , shape etc ... ? Thank you all |

Small capacitors should read "open". Large caps will show a "kick" of low impedance, but it will quickly climb and become very high. If the value remains low, you have a shorted cap. If you want to test a cap to verify its value, you have to get fancier. Applying 60 Hz from a small transformer (less than the cap's rated voltage) and measuring the AC current will let you calculate the capacitance and show if the cap is still within its tolerance.
