To answer your question. You have installed the CB in FRONT of the problem. The power goes from the battery TO your 30 CB and THEN to the circuit Board that has the 30 amp fuse. The problem is the CURRENT overload goes to the Circuit Board FUSE first. 30 amp circuit breakers will usually have a higher load before tripping. They make a CB that will plug into the circuit board in place of the 30 amp fuse. Usually when you have this type problem, it is the OEM's fault. They have NOT installed large enough 12 volt wire for the circuit. I would install a larger supply wire from the battery TO the Circuit board. The LCI install states 8 GAUGE for both Negative and Positive. If you do NOT have that Gauge, then that is part of the problem. Remember, regardless of what others have posted and complain about, IF the OEM does NOT install the correct wiring, it is NOT LCI's fault. FIX the problem, do not go around it. The 30 amp fuse is THERE for a reason. IF you bypass or modify, you may burn the control of the board. Doug
