Ampaynz1 posted a link to some permanent magnet alternators a few days ago that caught my interest http://www.windbluepower.com/Permanent_Magnet_Alternator_Wind_Blue_Low_Wind_p/dc-540.htm

It's PM so it would have to be disconnected from the batteries when no generation is wanted. The negative is not isolated i.e. it's provided by the alternator case. I was thinking about using a contactor to disconnect the output when it needs to freewheel and wondering if I could do this on the negative side i.e. connect the alternator +'ve output to pack +'ve and connect pack -'ve to vehicle chassis via the contactor. I'd appreciate any comments, criticisms, etc. This is on a 120 VDC nominal system with two contactor setup. I'm not worried about regulation at this point...

thanks
