Following a misfire, what is the next step after checking interface connections for dirt or damage?

• A. Turn on CLU, re-engage the target
• B. Re-connect interface connections ensuring they properly seat
• C. Ignore and try again
• D. Replace the round and re-arm

Answer: (B)

When a misfire occurs, the most likely fault is an incomplete electrical path. If you’ve inspected for dirt or damage on the interface and proceed, the next essential action is to reseat the interface connections so they are fully seated. Fully seated contacts ensure a solid electrical connection for the firing signal and the safety/arming circuits; any looseness or misalignment can prevent initiation even when other parts are okay. By reseating, you restore proper continuity and remove contact resistance or gaps that could cause another misfire. After confirming the connections are seated, you can continue with the next steps per procedure. Skipping this seating check or trying again with a poor connection can reproduce the misfire or create a hazardous condition.
