Hello, new to the group. I have a 1974 Mooney Ranger M20C and the annunciator lights (low vac / high vac ), light assy below the gear lever, pic attached is inop. The green "gear down" light works, the other three caution lights do not and do not light when the push to test button is actuated. I took it to a local shop, and they said the circuit board is toast and that's where it ended.
My questions - 1. Does anyone know the parts number for the assembly, I can't find it.
2. Does anyone in the group have a functioning one they'd sell if they have redone their panel.
3. If I cannot find one, recommendations?
I appreciate any help / info on the subject.
