With my dc generator, turning, and a volt meter hooked up to it, Im showing a negative result with red voltmeter lead to the red wire and black lead to ground. Why am I getting a negative result, and how should this thing be hooked up to my charge controller system? If I reverse the voltmeter leads, I see a positive reading. My natural assumption is the dc generator wasnt designed to work in this fashion, and is somehow working backwards? If this is the case should I hook it up to the rectifier/charge controller working as a negative output or a positive output? (I know this is pretty much the same question posed above, just trying to get my head around this situation) Thanks in advance for any input.
