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!
