put finger to keyboard and composed:

Well wadda you know.

I straightened the pins and put it in backwards.

At power on there was a click and the readings now are.

1. 0.23
2. 0.32
3. 0.64
4. 0
5. 0.82
6. 3.7
7. 2.57
8. 1.44
9. 3.35

For socket pins 1 - 9. The device is definitely in backwards.

I rechecked pin 5. It's +0.82 not -0.82, strange.

Pins 7 and 8 seem strange too.

Perhaps it's still not really a TA7317P

Old guy

Maybe the chip was damaged by your first attempt?

I think pin #8 is probably OK. AFAICS, Q7 (diode) and Q10 should both
contribute around 0.6V when the relay is closed.

I would think that pin#6 should be a lot closer to 0V.

I also don't understand why the voltage on pin #3 is so high.
