I just installed a Adventure Offroad GM CS130 Alternator kit off of ebay. On my 86 Samurai ,I supplied my own new alt. I've read there wiring plug doesn't sense the voltage and i need to rewire the Blk/Wht wire. But now i've noticed my temp gauge sits on the bottom and my gas gauge sits pegged at the top. They were working fine before I changed over, any ideas

?

Thanks
