M_Boats: 17 electricals

Any of you out there with a factory electrical system on your recent vintage 17 could save me a lot of time and aggravation. My lights all work, but the auxiliary receptacle will not run a spotlight (although it reads battery voltage on a VOM), and the center terminal is negative rather than positive. This is unprecedented on any 12 VDC system I have seen. Is it more likely that the battery was hooked up backwards, or that the receptacle was improperly wired. And what's with the inability to handle any current? Needless to say, comments will be appreciated, and all my electricity to charge the battery is "green" from the hydro plant a mile away.
