Its my way of publicly thanking everyone that took a minute to show their
appreciation for the Lists.
Won't you take minute and assure that your name is on the upcoming LOC? Tell others

=EF=BBThanks to all who have responded.
Today I had the time to address the problem at the airplane.
The easiest way (and costless - apart from my $worktime$) to solve it was to
leave the ground circuit which goes to the EFIS annunciator in the N.O. tab
of the microswitch and change the EFIS configuration to =9CActive Hig
h=9D (no need for the pull-up resistor), and connect the ground wire f
rom the LED lights to the N.C. tab of the same microswitch (SPST).
This way, when the baggage door is Open, the LEDs lights are fully lit and t
he alarm =9CBaggage door open=9D appears in the GARMIN monitors,
and when the baggage door is closed, the EFIS annunciator doesn=99t s
how and the LED lights are fully Off.
Yeay!!
Another problem solved!
Thanks
Carlos
P.S. - just out of curiosity, after I disconnected the terminal of the groun
d lead of the LED lights, and before reconnecting it to the other tab, the L
EDs showed a very low dim light whenever I touched any metal part of the air
frame with my fingers just holding the connector =F0=9F=98=B3.
These LEDs are really sensitive, they do emit light even with the tiny curre
nt which was flowing through my body...

The 20 amp alternator fuse is way too small. The purpose of that fuse is to protect
the battery from short circuits.
The fuse should be physically located near the contactors.
Use 18AWG for voltage regulator wires. The 5 amp regulator fuse is OK.
The panel switch and 5 amp fuse are not needed or desired. Eliminate them. They
are unnecessary failure points. Consider using 10AWG for the power bus feeder.
The 12AWG wire going to the starter contactor is too big. Replace it with 18AWG.
That wire needs to be fused. 5 amp should be good.
The 14AWG wires connected to the power bus are too big. Replace them with 18AWG.
Protect those wires with 5 amp fuses. Manufacturer's instructions take precedence
over my recommendations.

I'd remove the panel switch.

Will the fiberglass alone be strong enough to support the
avionics ? Do I need an overlay of some sort?
