[Elecraft] XV144 Overload test fails - Revisited

[Gerhard Schwanz]

Hi again,

some news:

I am able to trigger the condition manually when hitting rb5 with gnd or
when hitting the base of q7 with 12v (via resistor of course).

But still:
Removing J8 results in relay clicking and the light going dark on my XV.
When I am reading the circiut diagram correctly then the test procedure is
not capable of triggering the condition because:
- J8 action results in power loss on k3 which switches the 12V line
- without power on 12V line the relay K8 can not pull the contact
- so J3 is not connected to the ODC

Where is my mistake? How can I test the circuit?

BTW: I set up the XV for single wire connection and a drive of max. 5W

Kind regards!
