Voltage to data port?

Voltage to data port?
Anyone have the voltage values that you are supposed to get to each of the pins at the aldl port? With the ignition off, i got nothing except for 12V to pin #16. When i turned the key "ON", i got 5V to pins 6 and 9 in addition to the 12V to pin 16. Does this seem correct?

4 and 5 should be grounds and you would probably see 5v on 2 (again assuming it is an OBD-II DLC-you never confirmed).

If wired properly pins 5 and 9 are the only ones you need to scan OBD-I.

Yes.... ALDL = DLC. There is a picture of one above, and you asked what the "DLC" was, so I thought that would be very clear.
