Good catch!  I have fuses in both the "starter engaged" and "HP= U On" indicator lights for the very same reasons.
 
What voltage and frequency do you plan to use on your gonad exciter = in order to assure detection of the stall warning system alarm?

Fred,
 
Thanks, as I always wait to see who picks up the other possible failure.  I did say '"indication" circui= t' only since I wouldn't dare to presume to design such as w= e are all experimenters.  For years I have been harping on the same = problem with the 200/320/360/?? hydro pump power relay "indication" termi= nal that is fed from the pump motor power contactor and that ci= rcuit is "protected" by a 50 or 60 amp breaker whilst the wire to th= e panel indicator light might be a mere 22 gauge.  See if that can c= arry 50 amps if it shorts (do not yell "FIRE!" in a crowded cockpit)= =2E.... The Legacy plans wisely call for a wee diode on each "I" to the "= gear in transit" light to not only isolate each relay, but have it burn u= p before the fire starts elsewhere.
 
BTW, the "I" line from my pump is protected by an inline f= use (uh, 1 or 2 amps if I remember correctly) as is the "starter engaged"= circuit.
 
I love this stuff.............
