Installed the ELT. Van's has send me the ACK E-04 ELT. I installed the bracket according the drawing but then the ELT will not fit. The bracket must be shifted forward about 9/16" forward. Also the forward clip will not close when installed according the drawings. I installed the clips downward instead of up. I'm unable to get a valid GPS position test. Wiring is correct. Maybe the Dynon needs another setting.
