I am currently getting Warnings for  "Red" GENERATOR OFF" & "BATTERY OVERHEAT" , as well as the odd "Yellow"  "BATTERY HOT" & "STBY ELEC PWR ON".  I have "Reset" the "Generator" switch and I have the  "STBY ALT PWR" Switch in the "ON" position. If I reset the "Generator" the Red Warning disappears, but does come back on after a short period.

The first thing I would check is if the starter switch is in the off position.

Thanks for that Tim. That could be it. I am not sure of the Starer Switch position I had at the time as I have completed the flight. But, just to test, I restarted MSFS and went through another C&D startup and I was not getting these warnings and I know the Start Switch was in the OFF position.
