The generator can be run manually and transfer switch can also be run manually.All the "fancy" electronics do is to monitor for grid voltage and start the generator and activate the transfer switch when there is no grid voltage.Losing electronics does not remove transfer switch which simply is a motor operated mechanical switch.The issue is though if the switch has manual override option.I believe there are manual transfer switches available.
To Brian: maybe you should try to understand better how standby generators work before giving your "advice"
