Hi, I have no idea what the problem is with my build, so if anyone has experienced something similar, please help me out. Thank you in advance.

Here's what's happening. I am using a rectangular blitzbuck driver and standard 9mm diode. So I connected the driver to the battery tube of my host and set the current no problem, but when I hooked up the diode and turn it on, the diode flashes once very quickly then goes dark. No clue why this happens, but after, I tried again with my test load, and got a very stable 2.4 amps. But it does not work with the diode. I also tried a reduced current.

It does not seem to be a problem with the driver because it works with the test load, but I do not know how the diode could do this.

I want another opinion before I try another diode or maybe I would be better off trying another driver?

Here is a pic of my setup:



Any ideas on what to try?
