Bravo G1000/S-Tec 55X Electric Trim Issues

[jfdez]

So, at a loss here. Apparantly there is a fuse in the S-Tec box that keeps blowing when electric trim is in use by the autopilot. This makes the electric trim inop. Everything else works correctly i.e., trim servo, autopilot etc. Except, that once the fuse blows, only manual elevator tim is available. Avionics shop finds no shorts anywhere and no electrical faults on the trim servo. S-Tec's answer was to "loosen" elevator control cables, which does not make any sense in any Mooney! Any thoughts here? Thanks!!

Try a bigger fuse?

Was there resolution to this issue?

Hope it was an easy fix.

I also have a BravoGx which had this problem for over 3yrs, the system was made for the Garmin autopilot .The s-tec couldn't handle the torque of the tail I was told by a reliable source at Kerrville. I had the computer board changed 3 times and the fuse 4 times..Ended up putting in a new trim servo, also put and in line fuse before the computer so it would blow instead of the computer and/or fuse. Since putting it the new servo I have had no problems, mine also checked out good on the bench. I would try the inline fuse first. We are of the many glass per Garmin Mooneys out there. It has been my main headache of the plane
