I just put a battery tender on a EFI Fatboy. The wires were reversed at the plug when manufactured and I didn't catch it, so the polarities were wrong the first time I hooked it up. Surprisingly, the battery still fully charged when hooked up right but now the bike won't crank. It does not appear that the power is getting through. All the fuses are fine. The panel light comes on but the orange light on the panel, that you have to wait for to go out before starting, never does. The headlights don't come on when the switch is turned on, as they should. The horn and alarm work. I am thinking I blew the starter or system relay. Any ideas??
