Need help with 9600 wiring

Cut the bin full and shut separator off and swung auger out to dump. Unloaded grain bin and swung auger back in. Tried to kick separator in and no go. Had 71e code. Shut combine down and tried to restart. No go. Finally was able to short across starter and start machine. Engine ran fine. Was able to idle up. Gauges worked. Lights and A/C work. Header and reel height works. No separator engage. Can't start with key. Thought I would take it to shop and try to figure it out. Parking brake is engaged. Buzzer going off. Brake is locked. It is an early model with electric parking brake lock.Anyone ever had a similar problem? How did you fix it. Thanks for your help
