Ctc203AX PIP REG LM317T

I Have 2 Pip regulators LM317T,NTE956,SK9215, out of the circuit one of them is bad or both i'm not sure.Any body has one known good one please measure it for me please. i'm giving you guys what my measurements on mine is, measuered with diode test on the fluke 88.

pin 1 probe-to pin 2 probe+ OL, pin 1+ to pin 2- OL.
Pin 2-to pin 3+.865, pin 2+ to pin 3-.528, pin 1+ to pin 3- 2.404, pin 1- to pin 3+ OL.

now the only diference to the other reg is between pin 1+ and pin2- have 2.788 while the one i gave you all the measurements is OL could some one please tell me which one is good Thanks in advance

the first one seems ok . now

the first one seems ok . now if that 2.788 is on diode test thats  leaky. on those 203 chasis usually the flybacks go bad makes the power supply squeel.
