An electric motor needs 2 primary things for it to run. First, it needs power, second, it needs a ground to complete the electrical circuit. Normally this is controlled by the switch... In this case the wiring diagram needs to be compared to the physical condition of the wiring. If the on/off switch opens/closes the ground, then there is an alternate ground in the circuit probably due to a broken wire. If the on/off switch opens/closes the power, then there usually would be a short in the on/off switch, and the power is spanning the switch. .. Goog luck..
You can repair your wired headset that has a bad connection at any electronic store near you. No u can't I've tried
Fuses That "Blow" RepeatedlyWithout 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.

bad connection from the battery or alternator
In my experience most problems are either a bad ground connection, or a short circuit somewhere. Shorting will probably be due to a chaffed wire, or loose connection.
Most likely the cause is a bad connection in that particular electrical circuit. There is a lot of time involved in trying to find exactly where that bad connection would be. Not worth fixing, in my opinion.
Bad trans, bad APPS, failing alternator causing electrical noise on APPS circuit, bad lift pump causing electrical noise on APPS circuit, bad brake light switch, dirty grounds on batteries and block, etcBad trans, bad APPS, failing alternator causing electrical noise on APPS circuit, bad lift pump causing electrical noise on APPS circuit, bad brake light switch, dirty grounds on batteries and block, etc
a bad connection
The fuse is bad or there is loose connection in the circuit.
A bad connection, or excessive resistance on that circuit.
Generally a fuse burns out due to having a short in the circuit allowing electricity to travel to ground. Somewhere along the electrical circuit involved there is bad connection or a bare wire touching a metal surface.
Could be a loose connection somewhere, or a bad switch, or a bad outlet.
bad battery cable connection , dead battery
Bad battery cable connection or dead battery
The secondary fault circuit is generally a poor connection in the fuel pump circuit or possibly bad fuel pump. Check connection on top of gas tank and be sure to check ground wires.
In an electrical circuit, you'll have a charged circuit (the positive), and a ground circuit... a bad ground cable is a cable which is somehow not effectively completing the ground.. could be poor conductive material, a break or fray in the cable, an improper grounding point..
