Ok Progress… since I definitely and positively know each of the four relays and definite locations. And totally familiar with wire codes and color code key. I have focused on the needed relay feed tests . The “ Dip /main “ relay is fed fine from key turn .
The “Dip” relay however has zero voltage in all states . Key on or off . I’m checking for volts at the 12 v battery feed socket to relay. AND the 12v volt “Trigger” socket . Both dead 💀 with key on or off . Clearly this is part of issue . At least I know it’s not a relay ( kinda knew that , cause I changed them out many times ).
I was kinda surprised 😮, or was anticipating my test light to light up , from “ trigger” socket test ? Thinking the trigger 12v could still be present coming from the key on event ? It did not , and I just was surprised / bemused . Lol Even though the relay was definitely not getting the main 12v at that pin. So ? Means trigger AND relay feed originate / or string together from the same ( failed source ) . I’m going to remove rear of dash and delve into it tomorrow . Thanks 🙏
