Hi sgonzo,
First, I suggest that you visually inspected all your relays for any sort of obvious physical damage. Unfortunately, there is no simple test that you can do on the relay module outside the chassis to determine which one is causing the fuses to blow. I would recommend starting with 6 modules at a time and testing them, then testing the remaining 6, followed by testing 3 of the 6 in the "bad" bunch, then the other 3 and so on. This way should ensure that you blow the fuses 3 times, so 6 fuses and $18. I would also recommend keeping the 4 that you mentioned worked fine in one group so you can quickly eliminate them later if they happen to be in your "bad" group. Hope that helps!
