[DG] S3G as backup of SPX-SOL

Hi all

after reading the thread "SPX-5 as backup to EV-200" 11-01-2017, I would like to use my old S3G as a standby backup of the SPX-SOL.

As I have only ST1 network, I'll use a diverter applied to "off switch" contacts of both autopilots to have only one at a time working.

I think it's possible connect the solenoid and clutch cables to the respective contacts of both autopilots, but I don't know if it's possible to have the rudder and fluxgate sensors cables permanently connected to the respective contacts of both autopilots.

So before risking damage, I look forward to knowing the opinion of the guru.

All the best
Maurizio
