Could not work on the nose bowl today, the superfill did not dry overnight as it was too cold in the hanger, so…. I had to get the ELT working, it took: Several trips crawling back into the tail playing with switches 2 trips to Walgreens 2 trips to ACE 2 phone calls Who would have known the system needed two different odd sized batteries to make the system work. But the remote horn and panel remote are all working now.
