I'm building my second bass and this one has some pretty complicated wiring. (www.mybassproject.com/frankenelectronics.html) I've hooked it up and can tell I've got some problems but testing it is proving really difficult. Is there any way to tell for sure which coils have current passing through them? If I tap the poles with something metal I seem to hear a slightly louder pop on poles that I *think* have current flowing through them. This doesn't feel very reliable though. Is there any other way? Thanks!
