I ran wires in my 99 dodge ram for this amp. One directly from the battery for a 12 volt supply, one from the cigar lighter power for the remote. And one ground directly to the body via self drilling screw under the carpet. With a good fuse in the amp, as soon as I go to hook up the last of any one of those wires the fuse pops immediately. Where did I go wrong? Or have I caused damage to the amp.

It is fuse number 12 in the interior fuse box behind the panel just to the left of the steering column.
Fuse #12 a 20 Amp mini fuse that powers the Cigar lighter and OBD2 diagnostic connector pin #16 (12 volts)
a car amplifier should use an outdoor 2or so gague (very thick_) wire, ran, not to the fusebox, but to the battery, with a 20-30 amp under the hood, within a foot of the battery. the amperage your fuse will rewquire is based on the formula amps= wattsdivided by volts. a 240 watt amp on a 12 volt line would need a 20 amp fuse, just for the amp alone.
May help - fuses supply power but also needed is earth return to battery. This is usually black wires running from device to the car metal. To diagnose you need a multimeter. Check body of cigar lighter is connected to the chasis with meter on ohms. (continuity test) good is zero ohms. If earth problem, check under dash to ensure all earth wires connect to metal chassis. Then with ignition on, check centre pin at back inside cigar lighter has 12 volts to side.
If not then check fuse has 12 volt to it, Now you can get to the fan, repeat all the tests on fan. Best wishes, its tedious work.
The ASD relay supplies battery voltage (12+ volts) to the fuel injectors
and ignition coil(s). With certain emissions packages it also supplies
12-volts to the oxygen sensor heating elements. The Fuel Pump Relay is a
separate relay controlled by the ASD relay input to the PCM. Fuse #12
(10amp) provides 12 volts to the coil side of both the relays and the
ignition switch. Fuse #6 (30 amps) supplies 12 volts to the output side
of the relay. Fuse #16 (15 amp) from the relay output to the Oxygen
Sensors and Fuse #26 (15 amp) relay output to the PCM. Fuse #24 (20 amp)
is Fuel pump relay output to fuel pump. Fuse #19 (10 amp) supplies 12
volts direct to the PCM. look for burned or melted wires in the offending circuit. sounds like you wiggled a wire while installing new relay.
It is very likely the cigar lighters circuits wiring sizes are not suitable for the amp draw of the compressor, i suggest you not use it as a power source. Buy clip leads and solder them on and use the battery as the power source. You can obtain the electrical clips from any hardware store.
Hello! No, not at all...After you change the EGR, disconnect the + battery terminal for 3-5 minutes...Reconnect...And if the EGR was the cause of the fault the code will clear...Make sure you have the stereo code...If not, connect a regular 9 volt battery to a cigar lighter plug (pay attention to polarity)...Plug it into the cigar lighter socket before you disconnect the battery...It will maintain power to the stereo...Guru...Saailer
Even thought the plug in is 12 volt. It's ouput is different. Most electronics have different ranges from 3-9 volts. Does the 12 volt charger put out 12 volts? If so, it would burn up the electronics' capacitors on their power supplies. How is the car's electronics doing? Are they too failing? If so, that would be a faulty voltage regulator, if not, I would hook up anything you use to the radio wires. You cannot plug in anything directly to battery no matter what the person told you. Batteries charge, than release charge, a contiuous cycle. The power output is speratic and anything hooked straight up to the battery will need a fuse.
