PNP TO-218 and TO-220 package (TIP-36C, TIP-42/A/B/C, TIP-107, MJE15031)
Place the red lead of your DMM on the metal tab of the transistor
Probe each of the flanking legs with the black lead
.4 to .6 volts is a normal reading. Readings outside of this range indicate a failed transistor
Probe the center leg with the black lead
A "short" should be seen. If not, then the transistor has failed.
