1992 Chevy C1500 350 5.7ltr Will Not Turn On Any Accessories Or Try To Turn Over, What Can I Do

Last Tuesday, SW Michigan was hit with blizzard like temps, 50 mph winds and blowing light snow. the next day I went out to start my truck, turned the ignition to the start position. All my dash indicators, radio, and buzzer came on. I went to turn it over and everything cut out EXCEPT my head lights, inside dome light, and under-hood light. I have installed a new starter, and ignition switch; checked all fuses, and used a test light on my relay control. I tested the posts on the starter solenoid. the main hot wire to the battery tested fine, but the other did not test alright. I have run out of options that I and other family members have told me, please help!!!
Last wednesday, I went out to start my truck, turned the ignition to the start position. All my dash indicators, radio, and buzzer came on. I went to turn it over and everything cut out EXCEPT my head lights, inside dome light, and under-hood light. I have installed a new starter, and ignition switch; checked all fuses, and used a test light on my relay control. I tested the posts on the starter solenoid. the main hot wire to the battery tested fine, but the other did not test alright. I have run out of options that I and other family members and mechanics have told me, please help!
In addition to the first four answers I did check with a technician and they told me to check my connections. The battery works fine, only a year old and connections are tight. I also checked with tester, (+) on battery to (-) on solenoid post and it lit up. I did try starting in both park and neutral positions. Any suggestions.
Remember, head lights, dome light, and under-hood light has no effect on whether ignition is on or off. when i turn on the ignition nothing happens, it used to,but now it will not. Nothing happens when i turn the key backwards, forwards, or trying to crank the engine.
I can try to move the ignition switch to see if it was centered. I can also find the neutral switch to see if it has gone bad. It would cost me more to take it in to get it fixed than to see what the problem was for myself. I needed a new starter and solenoid anyways, because it was the vehicles original and it was going out.
The way i see it the more i change the less of a problem down the road i will have depending on the parts. I will try these two options and return with answers.
