Stupid electronics question:

I have a Bart preamp which accommodates either 9V or 18V. Are the batteries linked in parallel or series to accomplish the 18V configuration?

What's really scarey is that I just installed a new light fixture in the kitchen. Black to black, white to white, ground to ground...I think I got it right. However, I punted when it came to the trial run. "Hey honey...go try out your new light while I hide here in the corner."
