cleaned battery cables-now won't start ls400

I just cleaned the battery cables on my 97 LS 400, now it won't start. Gauges all come on, and cable are tightly secuyred. Car doesn't make any noise when trying to start - just gauges come on and that's it. Does something need to be re-set or is there a security feature I need to address? Thanks
