Question about trouble codes

Got an 86 F1 50 and trying to run the trouble codes down either I don't have a check engine light or somebody unplugged it or the bulbs out but I'm using the test light method,it lights very quickly the second the ignition switch is turned on and the second light is very dim like it's not getting full voltage,there's a short pause and then it flashes four times pauses and it flashes five times and doesn't flash again what are these codes mean? Is there a chart that explains these numbers?

That's not right at all, are you sure everything is connected properly?

Here are the official Ford procedures on pulling codes, there's a section for the blinkenlight method in there:
