You hooked the ground wire to you amp to a hot wire. The hot wire is black and it's the hot wire to the cigarette lighter. I used to be a Ford mechanic and saw this alot and charged people lots of money to fix their Stupid mistake.
The cause of this issue can be blown fuses in the car. If the fuses are not blown, there is a fault in the electrical system.
No unless the belt driving the alternator and cooling fan breaks
maybe the bulb is burnt
If you mean no electrical power then the computer couldn't give you a warning light because it has no power to operate. Common causes of lack of electrical power include a blown fusible link, a blown main relay ( not all cars have them ), a dead battery or a severe short.
a short in the wiring system A blown fuse is caused by a short or an over current condition.
fuses are blown, or bulbs are blown
A dead or weak battery is one of the more common reasons for a car to experience electrical problems. A bad alternator, blown fuse, or broken wire are other common causes.
electrical inpulsis to the muscles instigated by the autonomic nervous system.
You may have a flat battery, a blown fuse or a loose wire. You need to trouble shoot your electrical system to find the fault.
There are a variety of reasons the hazards lights may not work. The flasher module could need replacing. The fuse may be blown. The bulb may be blown. There could even be an electrical malfunction.
A car battery causes the headlights to shine
some general causes: leak in cooling system (including possible blown head gasket) resulting in loss of coolant; defective thermostat
pressure test the coolant system you will find a blown intake or head gasket
did you recently pull the horn fuse? That's what happened when i did
Either you have low coolant, defective cooling system (bad radiator) or a blown head gasket (or all of the above).
No likely but possible if coolant is leaking out onto some electrical component.
The main cause of battery drains is a bad electrical system. The electrical system is normally powered by the alternator and once the alternator goes bad the battery has a hard time holding a charge,
battery no longer can store a electrical charge, a charging system failure, a parasitic draw,
A short in electrical system within the battery where two cells short together.
Several causes may prevent a car to run. The most common is related to the electrical system.
In an electrical system over load means over current.
o.e. radio may be part of alarm system. or, blew out fuses. may have caused electrical damage(cut wires, blown electrical components).
99% of the time it is overheating of the engine.
