N1 gauge problem.
Here is a question to all you guys.
We operate a 206.
Everything was working fine until yesterday, when one of the guys went to start it. The N1 gauge is not moving when you hit the starter, but you can tell everything is working by listening to the starter. When you light it off, the gauge jumps up when the speed hits 30% and works fine from there on up. Also when you shut off the engine, it spools down all the way like it should.
We checked the gauge at an avionocs shop, worked fine. We swapped the tach generator for a new one, and we checked all the wires in between for continuity. We also tapped the gauge to see if it was stuck.
Any ideas??
