Good job, Eric! Have you tested the LED to see if it shorted or opened?
I assume it was a complete short. I really don't have any technical knowledge when it comes to electronics. The Crack was my first project - the Reduction I built a couple weeks ago went much better after the first build. I just figured it was time to install the Speedball upgrade.
I tested D1 with the diode test on my multimeter and I couldn't get a reading. I did get a reading on D2. Though after replacing D1, it lit up, but D2 didn't and the voltages were off. After replacing D2 - everything lit and voltages were spot on. Glad to have this back. Had a lot of music to listen to before going to Forecastle Festival in July.
