Let's see a picture or two....

When you say that each black wire is hot, is that true if the dimmer is off? If the dimmer is working and off, then one black wire should be hot (from the source) and the other not. Each Romex cable should have three wires (black, white, and green); is that what you see?

Yes, I didn't remember if Romex used green or bare wire for the ground.

If current romex, itll be black, white and bare copper.

does this light turn on from two possitions? do you see a red traveler in there?

like stated above, a photo or two would help.

Looks like The dimmer switch is broken and stuck in the on position which is reason why im getting power on both black wires, a new dimmer should solve the problem, thanks for all your assistance

When you wire in the new dimmer, avoid bad practices, like that wire nut wrapped in electrical tape which may be undersized for the number of wires.

As shown in the wiring diagram, the dimmer's red (hot) and white (neutral) wires connect to the light, the black is the always-on "hot" wire, and the yellow is ground. Excellent replacement dimmers are the Lutron LED+ (examples: CTCL-153PR-WH "Skylark" and DVCL-153PR-WH "Diva")
