Problem: in flight, the ammeter is pretty much pegged at 70A...turning off some of the load reduces it to about 50A (1977 turbo-Arrow). This is new and I have never seen it read this high.
My mechanics put a clamp gauge on the alternator and measured the output at 20A, while the gauge was reading 70A. We have tested the gauge and it seems to be working properly. I am told that the problem is probably in the ammeter shunt or the shunt wiring.
Can anyone tell me where this shunt is typically located? I have never had this problem before in an airplane, and don't think I have ever noticed this thing before...I want to see it before we spend alot of time and trouble to change it.
Any idea where to look for it? Anyone have any photos of where it typically sits in the airplane?
