It's as if no matter when I do the flash fires as bright as it can. Sounds like you have it either in Manual mode, full power, or in eTTL mode but the flash is not communicating properly with the camera (most likely caused by a bad connection) so it fires at full power. 1D Mk III | 450D Gripped | Σ 30 f/1.4 | 85 f/1.8 | 18-55 IS

It sounds as if the circuit board which regulates output is acting up...send it to Canon repair. You need to give me OK to edit your image and repost!

I took a part the base of the flash and found a black wire that was loose. After searching around I found where it goes here https://photography-on-the.net/forum/showthread.php?t=932943. put it back together and the flash is working like new!
