The proper 'fix' is for a qualified technician, who knows what he or she is doing, to troubleshoot the involved circuit, find and identify the defect, and make proper repair, BEFORE replacing the fuse again. The fuse or circuit breaker is doing what it was designed, intended, and installed to do, protect the conductors and components of the circuit which it serves. When a fuse or Circuit Breaker 'blow,' especially if it happens repeatedly, is an indication of an UNSAFE CONDITION in that circuit, usually a short. įuses are safety devices designed and installed in electrical circuits TO PROTECT the conductors and other components from short circuit conditions and/or overload conditions which cause an extremely large flow of electrical current, which causes overheating of the conductors that results in damage to the insulation and the conductors.Īnd in a worst case scenario, the probability of a FIRE which could destroy the vehicle, house, or other structure in which the circuit is located.

Therefore, the following generic answer can be applied to any electrical circuit, whether in a vehicle, or in a building, or whether alternating current or direct current. Without being able to 'hands on' troubleshoot the circuit served by the repeatedly blowing fuse, none of us can identify the specific cause/defect which is causing your problem.

Answer 2 - More ExplanationThe following answer is a cut and paste from my previous answer to several similar questions. Too large of a load in an electrical circuit can cause a fire. Not unless the circuit was built for a 15 amp load.

10 amp fuse
