Does anyone have an electrical system schematic of their aircraft they
wouldn't mind sharing, a big plus if it has a EC2 and EM3 (or former EM2).

One other thing, i was looking at solid state circuit breaker offerings and
before i dismissed the VPX as being too costly i noticed that they only use
1 contactor between battery and unit, that means (to my understanding
anyway) that despite all the redundancy's of having 2 separate circuits
within each unit, if the battery contactor lets go your'e still out of luck.

This leads me to want to have a separate feed from the battery to the
essential bus, what about cutting out the 1 amp draw from a second battery
contactor and rather have a manual "pull on" type contactor if it exists,
has anyone tried this

Alex,

I am wiring this into my system- 2 of them actually. One with a key and one
without.  battery switch

If by some chance the continuous duty solenoid fails, I have a manual
backup.  Also, I will mount the keyed version inside the cockpit (my battery
is going to be behind the back seats) and when I leave the plane- presto no
power.

Kevin try tilting your LCD display monitor vertically :)
Web pages and email will be much easier to read and screen capture
will be more comprehensive.

You will love it and your email line length will decrease :)
Less work for me.

8.5 by 11 paper is longer than it is wider.
