REPLY

Hello ----------
=A0 I'm aware of the failure and h= ave the unit here for repair.

=A0=A0 Like a thousand other critical = details in building an aircraft, it is not possible to explicitly spell out= all of them.=A0 The precise method and hardware used to accomplish it are = not part of the EC2 or the instructions. The first paragraph of the install= ation guide does say the following:

"Need= less to say, the quality of installation is just as important as the qualit= y of the hardware itself.=A0 It is not practical to include a = course on proper electrical wiring practices in these installation instruct= ions, but it is imperative that proper wiring techniques be employed during= the installation of the EC2."

It was my thought that avoiding the presence of loose metal objects ins= ide an electrical device that your life depends on fell into the category o= f=A0 "needless to say".

Nevertheless, a cautionary note mi= ght well be worth adding.=A0=A0 As also stated in the first paragraph of th= e instructions,
" I want your project to succeed and your life to be a long and = happy one. "

All the best,Tracy Crook, =A0=A0 RWS=A0=20
