Fuses That "Blow" Repeatedly
Without being able to "hands on" troubleshoot the circuit served by the repeatedly blowing fuse, none of us can identify the specific 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, whether direct current [DC], or alternating current [AC].
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 repeatedly "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; that is to protect the conductors and components of the circuit which it serves.
The proper "fix" for this issue 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 people 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 oversized fuse would almost guarantee damage to the wiring and the probability of an electrical system fire.
What would cause your fuse to blow when you turn on your lights on your 1993 mazda 323 the fuse to the tail lights on dash lights blow?
Short in the wiring or light bulb socket.
A loose or corroded ground wire will cause the fuse to blow. Check the ground wires on your brake lights.
There is a shorted wire or bulb in that circuit.
short to ground check bulbs in tail, corrosion can do it
Check bulbs or wireharness at back of bulbs.Switch handle that turns lights could be bad Toyo joe
bad wiring or ground somewhere in the harnesses or fuse box
I'm not sure I understand your question. I can't tell if you have one or two different fuses "blowing." The only thing which causes fuses to "blow" is a short circuit condition in the circuit which the fuse protects. IF you have two different circuits blowing fuses, then you have at least two short circuit faults. j3h
If ALL dash lights don't work turn the headlamp knob clock wise or counter clock wise. If that isn't it check for blown fuse. If all fuses are good, replace headlamp switch.
because you hooked into the lights ground I bet usually you blow the fuse everytime you turn on the lights check your radio ground
What year is the vehicle? Did you check the fuse?
A short circuit. Look through your connections to your 'lights' and make sure there are no short circuits. If you want to know about short circuits see related links below.
