Fuses That "Blow" Repeatedly
Without being able to "hands on" troubleshoot the circuit served by the repeatedly blowing fuse, no one can identify the specific cause/defect which is causing your problem.
Therefore, the following generic answer can be applied to any electrical circuit, whether in a vehicle, or in a building, or whether alternating current [AC] or direct current [DC].
Fuses [and Circuit Breakers] are safety devices designed and installed in electrical circuits TO PROTECT the conductors [wires] and other components from short circuit conditions and/or overload conditions which cause an extremely large flow of electrical current [measured in Amperes], which causes overheating of the conductors that results in damage to the insulation and the conductors. And 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.
When a fuse or Circuit Breaker [and replacement fuses, or "tripping" Circuit Breakers] "blow," especially if it happens repeatedly, is an indication of an UNSAFE CONDITION in that circuit, usually a short.
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.
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 [s], BEFORE replacing the fuse again [with the properly sized fuse or before resetting a circuit breaker].
Some ignorant few will suggest installing a larger fuse or breaker to solve the problem, BUT that will only increase the hazard, not correct it. Do not follow "bad" advice by installing a larger fuse in a misguided attempt to correct the problem. To install an over-sized fuse would almost guarantee damage to the wiring and an electrical system fire.
A fuse that keeps blowing is an indication of a malfunctioning ignition. The ignition may be the culprit or the wiring leading to the ignition may be the problem.
If it blows when trying to crank, the starter has failed.
the starter has failed.
your car wont start!
i have a 96 dodge avenger 2.5 and it keeps blowing my ignition switch. any idea why?
Problem with the starter. Possibly locked up, or shorted out. Remove and test the starter.
If the 1990 Chevy Lumina is blowing the DIS 10 Amp fuse when the ignition is on, check to make sure that all wires coming from this fuse are grounded properly. Also check to make sure the starter is wired properly. There could also be a loose wire in the dash near the ignition.
It keeps sparks out when ignition of the engine
1995 Audi A6 Number 8 fuse keeps blowing. Fuse runs domelight, reading light, clock, memory seat, memory side mirror, trunk light. Fuse blow with car just sitting in the drive way parked with key out of ignition. Fuse start to repeatly blow all of a sudden.
Motor hasseized.
2006 Ford Focus rear defroster keeps blowing the fuse immediately after replacement
it keeps the firing sequence
