OK so somehow the 510 connector came loose on the infinity I bought from the classifieds and when I thought I was unscrewing my carto i was turning the whole shebang which snapped the wires off of the connector. I went and bought a new connector, soldered the wires onto it and....nothing....not a damned thing. batteries are fully charged connections are tight...and nothing. I think she's dead Jim....I want to hold a funeral, does anybody play taps?
