Wouldn't you know it. The first flight on after fixing the issue with my toe brakes in the Q400, I notice the Main Bus Voltage decreasing at a steady rate with all battery switches flipped to the "on" position, the APU and APU generator on, and the main bus tied. I tried using external power instead but the Main Bus still showed a steady discharge. Help?
Q400 Battery Discharge with APU on

I started work on the electric system but didn't finish... otherwise the q400 would be cold and dark, too
Even it the battery goes empty it should not affect anything yet.

See but what is funny about that is that it does effect the aircraft when I run out of battery. The flight displays stay on but the overhead panel goes dark and the engine starting system wont work. The battery discharges at a constant rate with the APU on or off. When it runs out I have no way of starting the engines so I have to reset the flight.

I was baffled because I put the aircraft in a cold and dark state, started the APU, and walked away to get food. When I came back the OH panel was dark and the DC BUS showed 0 volts. The APU GEN showed a load of 0.50 which led me to believe that it was charging the battery but clearly it wasn't.
