I don't mean to be rude, but I'm shocked it works. there are a number of wires that have too much bare metal exposed. also, there were a number of points on your install that looked like it either had too much solder and could be contacting other points it shouldn't or some of the wires could be contacting other points and/or other wires.
You need to run through your install with a multimeter on continuity mode and check to make sure that your solder job is not oozing over into other components it shouldn't be.
If you need help, post a question in the
forums, not my PM inbox. Thank you.
