No electrical power to console. 725D

As the title says, I have NO power to the console. Wont start and no lights or indicators on console. Brand new battery. The deck actuator works fine, indicating good charge on new battery. A couple of weeks ago, when I tried to start it, I got weak lights on the ignition when attempting to start and a sort of buzzing from the engine area. This made me think the battery was at fault, so I installed a new battery. Any idea where to start with troubleshooting?



Thanks in advance for any replies!!!
