1997 Mitsubishi Eclipse battery replaced and still no power

I replaed the battery, and still have no power. Nothing what so ever. Where can I access a manual to verify it is installed correctly? I never had an unser manual. I don't believe I have a dirty connection since I cleaned all connections. Any other suggestions on what the problem might be? I can't see paying 100s of dollars to hear that I had the washer/cables connected in the wrong order on the battery. Poasts are on the top of the battery.
