Hi I am fixing my copter from a recent run in with some power lines. I'm having issues on startup with my copter giving me a Bl - missing error and the status light not coming on, on the abuse mark I2C board. I intermittently get the flight control box in koptertool going green for a second - then back to red, and the copter looses connection to the mk on occasion as well. I'm wondering if there an issue with my I2C connection or is this something on the flight control board or on the abuse mark. Not really sure how to more accurately diagnose the problem. Any advice would be greatly appreciated.
I suspect that the only way you're going to find the problem is to start replacing pieces -- e.g. the Abusemark, the cables, and/or the Flight Control. I would do them in the order of least expensive to most expensive. Andy.
Rory have you connected the Abusemark to the computer to see if the programming is still intact? That old be a quick way to check that item.
