| The transistor junctions you tested are GOOD. But what about Collector to Emitter? Should not measire a reading either polarity of leads. | |

| just a quick question regarding testing 2 transistors
transistor 1 is a Silicon PNP Epitaxial Type. multimeter set to diode function red probe to base, black to collector: measures 647 red probe to base black probe to emitter measures 655 reverse probes does not measure a reading. transistor 2 is a Silicon NPN Epitaxial Type. red probe to collector, black probe to base measures: 654 red probe to emitter, black probe to base measures: 660 reverse probes does not measure a reading. do these look like they are good transistors and measuring ok ? thanks |
