@SkipperMacz. That i a brilliant suggestion SkipperMacz. I just reconfigured my Master Alt button in the settings (see screen shot) and it works. Thank you so much, you just made my day.

@SadBucket. Thank you for your suggestion. I do not use chase plane. I have also reinstalled this plane 6 or 7 times, the problem will no go away. Thank you again for replying

@PhilTFC On the electrical schematic the Alt Master is showing as off and not feeding power from the alternator to the main bus. The anomaly is that the Alt Master switch is showing as on in the panel image. Could this suggest some conflict is causing the Alt Master to not properly turn on?

I've noticed my alternator being turned off (visually) with some interactions through Chaseplane. Other users have mentioned weird issues related to chaseplane. I wonder if something WASM related (or just some other conflict) is causing the issue through another addon.

This is a screen shot immediately before start up
This is the air con at 6:30 in the morning with an OAT of 61 F. I have tried pressing and holding the Orange ALT 2 XFER button but nothing happens. This is the screen shot of the engine after 10 mins at 2000 RPM. The battery is at 76% and continuing to drop. This is a screen shot of the Elec 10 mins after start up, again RPM set to 2000RPM There are no fuses popped out as this screen shot shows. All the failures are turned off This is a screen shot of the lower panel after 20mins at 2000RPM This is the engine state after 20mins at 2000RPM. as you can see the battery is not charging
I hope i have covered everything. After 30 mins at 2000RPM the electrics shut down, battery at 20% and still dropping.

First guess would be.. RPM too low.

@PhilTFC I would need a little more information to help you troubleshoot this one. Screenshots of the cockpit with all the instruments and switches visible, and the electrical schematic on the tablet would be very helpful.
