I tested the resistance between Terminal 3 and A3 and got nothing.  Now, I've not heard it called DC Resistance before.  I just measured resistance like I normally did.


I get zero.

Zero is not nothing, zero would mean you have a short between A3 and terminal 3, which would be a huge problem.

On the other hand, OL would mean infinite resistance, which would be a likely proper outcome from this measurement.

It was the LED!  (I know, I know.  It was >I< (not a defect in the LED) who mangled the thing so much...)

As soon as I removed the solder to re-solder it, the LED fell.  The wire on the un-banded side fell away, clean, from the LED.

Question:  Do I need the LED or can connect A3 with the center with some 20AWG wire?

You can connect A3 to A8 with a jumper wire.  Do not wire A3 to the center post of the 9 pin socket.

OK, I ordered the replacement LED's.  In the meantime, I connected A3 to A8, as a temporary connection.

Everything looks good... except:  The four places I should be getting 0V, I'm getting 0.002V, on terminals 3,6,8,10 (when setting my meter to VDC "2";  It reads 0.02V when setting the meter to "20" and 0.2V when setting to "200")

Resistance checks are normal.

If I told you that you had two tenths of a cent in your bank account, you'd tell me that you're broke.  That's plenty close to 0V.

Whew!  Thanks so much! (I didn’t know if it weren’t exactly zeroing it meant something. Like leaking. )

Spent about an hour with 650’s and Verite Closed. Love this thing!

This help was amazing. Thanks again.
