Electrict Scooter has voltage, but no go.

I transported a working eGo Classic 2 on a trailer across town and now it is not running. It was not a rough ride by any means. Each battery measures 12.5V and together 25V. The charger outputs 27.7V. The main capacitor is holding 25V. Relay (if that matters) tests fine. The main 40A fuse is good, as is another 12V fuse (probably for the head/tail lights).
When I turn the key (go fast/far), I hear the 'click' in the controller. The first two lights on the LED voltmeter blink back-and-forth. Throttle does nothing. No go. Any ideas? Anyone know what those two LEDs blinking mean? Thanks!
