Oops my mistake, there was no schematic in the daily digest that is emailed to
me. Now I see it on the online forum.
Most aircraft have the battery contactor and starter contactor wired in series
so that the starter can be shut off in case it welds shut. There is no way
to disconnect the main alternator from the battery. Moving the alternator wire
to the other side of the battery contactor will fix both issues.
Will the avionics momentarily lose power when the avionics master switch is
operated?
Do the master switch and alternator switch have a center off position? There
needs to be a way to kill power in case of smoke in the cockpit. Most pilots
are familiar with switches being off when in the down position. Switches that
accomplish your goals are available that are off when down.
The 22mfd capacitor should be 22,000mfd.
There is a hot wire from the battery to master switch terminal 5. If it starts
smoking inside of the cockpit, there is no way to shut it off.
