For testing electrical circuits, the minimum you need would be a test lamp which could be easily obtained from any parts store. Without any diagnostics tools, some diagnostic procedures cannot be performed and you are not going anywhere.
At the ignition switch, test for voltage at the Pink wire with ignition switch turned to ON and while cranking. If voltage is not available, the ignition switch is bad, unless both red wires does not have voltage as well, then JDL has mentioned the fuses to check. When power supply is interrupted, the chime would not work so a faulty ignition switch fits into it.
Forsman is correct about knocking some wires looe so it is not going to be easy except if you feel that it is related to the work you did, you have to back track and recheck connections.
For wiring circuits, I have attached the engine control wiring schematics. Had to break them up as the complete diagram is too small to be ligible. Hope it is helpful.
