How do I investigate parser conflicts?

I noticed that changes I made to the Parser on my branch increase the number of reduce/reduce 
conflicts. Are there any tools/techniques/etc I can use to investigate this? Or do I just have to 
use trial and error (possibly guided with some knowledge of parsing)? Specifically, is there any 
way I can check which productions are causing conflicts?
