I have a transformer that came out of a microwave, I wanted to make a step down transformer out of it. I got playing with it and made a weird discovery If I put 12 volt dc + on one of the primary connections, then hooked the other end of the primary to one of the 3 secondary connections and the other end of the secondary to the neg side of the power unit. The center leg has anywhere from 73 to 100 volts on it with over 10 amps, it bounces back and forth, it also will light a 75 watt light bulb with the light pulsing I'm lost at what I did. Any ideas I forgot to mention that I used the transformer base as the ground of the 73 to 100 volts

Where are you getting the 12 Volts DC from?
Obviously Not from a Battery.
Probably from a Battery Charger with lots of AC ripple.
Because Pure DC Can't be transformed up or down in a transformer.

The power is coming from a Aston model RS- 4A the tag says 13.8 volt DC 3 amp continuous/ 4 amp for 60 sec. or less. It's a power supply that I run a CB radio off of, Sold in an electronic store. That is what puzzled me.

You really need to study transformer basics and electronics before you hurt yourself. rmeyn
