    Umm, that red wire that went to the ammeter is also what sent power from the alternator to the batteries. /forums/images/graemlins/shocked.gif When you removed that, you stopped charging the batteries. Run a wire from the alternator output (8 or 10 gauge) to the battery (or to the battery isolator input, if you have a battery isolator). That will restore a path from the alternator to the batteries. /forums/images/graemlins/cool.gif
