2000 3.6 will not turn over
 

I have a 2000 Isuzu Rodeo 3.6. When I switch the ignition switch on the dashboard lights will light up but the radio the clock or the overhead light aren't working. When I turn the ignition switch to start it's just like there's no battery there or anything. Are there any fuses I may have missed I've checked every fuse that I can check under the hood and under the dash. A couple of months ago I changed out the ignition switch which wasn't the problem but since I already switched it out I left it. Last Friday I installed a new driver side window switch. Car ran great Friday Saturday then Sunday morning my wife left and came back home and we got ready to leave again and it was just like it was dead. Would not jump off or anything. Check the battery it checked out fine. Does anyone have any ideas? Thanks
