SpletThere are two ways short condition of the zener diode can be checked or verified viz. resistance test and voltage test. Resistance Test: In this test, set the multimeter in resistance test mode. Now connect the Positive or … SpletI believe age of transistor, not an open diode*, is what caused the transistor to short, but now would be a good time to be absolutely sure before risking a new 2N3055 transistor. (*side note: in this case, coil diode cannot be shorted or fuse would have blown instantly when coil was manually test fired.)
Splet02. jun. 2007 · diode is the steady state current for the coil, under the highest supply voltage. If the diode is rated for a continuous current equal to or greater than the coil current, the brief inductive quench can't possibly overheat the die.
