The Bad news is the newly installed odyssey ODS-AGM16L battery was installed backwards. When the Master switch toggle on the side C/B panel was placed "ON", the wire and a portion of the insulation from the Master relay center post to the master switch overheated and insulation melted in a section of this wire. No start was attempted. Placed the master switch "off". I replaced the master relay,diode and wire to master switch. Then selecting electrical power to the circuit with the master switch toggle "on", all airplane systems were powered and worked normally. Selecting the ACS A-510-2K key switch to "START", THE "INSTRUMENT" 10 A C/B popped. Master switch placed "off".
So far I have replaced: Master relay,diode, center post wire to master switch, (two post) starter relay (internally grounded) and diode. Also have checked voltage and continuity to selected switches, wires, etc.
This 2012 RV8-A came from the builder(now deceased) with many manuals but no builder electric diagrams. I have Van's OP-10,-11 in the manual to look at. The airplane has about 385 hrs total time.
Electric equipment: SKY-TEC FLYWEIGHT 149-12LS starter, PLANE POWER AL-12-E 16013 alternator 60 Amp, Dynon Flight Deck D 180,txp and VFR radio.
Issue not resolved!
