Need wiring diagram for output cable of an Targus APM12US-1 DC Auto/Air Adapter

Technically, Yes. If there is damage to the wires but you know the AC-DC adapter is still good. There is a small single sided PCB inside the adapter that houses the transformer and step down/rectification circuit. There are two wires for the input (AC from wall which are hot and neutral) and two for the output which is your Ground and +18-19V (can't remember that particular voltage off the top of my head.) If you need to replace the plug that goes to the wall, check your plug type (the one that goes into the adapter) and order/buy a new one. That can be replaced with any plug that fits a desktop power supply. If you need to replace the plug that goes into the computer THEN you'll have to open the Adapter box. The two wires coming out of the board into the cable can be de-soldered. Just make sure you purchase the correct size/type tip (plug) for your computer and solder the positive and negative in where you removed the ones attached to the damaged cable.

Once you have soldered your new cable onto the motherboard, use a good epoxy to seal the box back together. They are not "user servicable" therefore, there are no easy to snap on/off clips, you will have to use a good adhesive. Also, TEST YOUR OUTPUT BEFORE PUTTING IT IN YOUR COMPUTER!!! Read the bottom of the Adapter and see whether the center of the plug is positive or ground, connect your DC voltmeter accordingly and make sure that the output voltage matches what the adapter says. It may be .2-.3V higher than what the adapter says because there is no load (your laptop) on the output but as long as it's no further off than that, you're good!

Good Luck!

PS: There are capacitors in the adapter circuit that can hold a VERY large charge and potentially hurt or kill you! You can also completely destroy your power adapter if you do not know what you are doing. Find a couple of youtube videos on the subject, there's tons of 'em. I am not responsible for anything that you attempt without having the proper skillset. For anyone handy with a soldering iron and familiar with electrical circuits, it's an easy fix.

Are you asking for the wiring diagram inside the main Battery?

If so, due to very possible injury, or death to you, there will be No solution.

Now, if you are talking about what is the polarity for the plug of the AC adapter, (Charger), that plugs into the DC Power Jack on the laptop, (DC _IN), then I'm on board.

The Center Hole in the plug end is the Positive ( + ) connection.
This is where the Positive (Red) probe lead of the multimeter goes.
The cylindrical outside metal shell is the Negative connection.
The Negative (Black) probe lead of the multimeter touches here.

Voltage is 19 Volts DC.

Wiring diagram for the inside of the AC adapter itself?
No gottom.

The wattage is to different, the wattage for the adapter is 90watts, and the charge for the advent is only 65w.

You can always try it, but you risk damaging your battery, or motherboard.

I know this sounds odd but use whichever one is the best fit and works. Also I suggest that you compare them carefully with the original noting differences in length, diameter and construction.
I think you will find that one fits better than the others.If it works and you don't have to push too hard to locate it, and it stays in firmly and connects OK then it will be fine.
regards
I hope I have been of help but please do not hesitate to ask if you have any further questions.

you inverter was not fully charged because it requires a 110/220 v ac as specified in the manual; to charge it so it is impossible for the aircraft 15vdc to charge it

AC adapter? Test the output voltage.

Use a multimeter.
Stores like Radio Shack, Walmart, and auto parts stores, for a few examples have cheap one's you can buy.
About $12.

Set the multimeter knob to DC volts, and the 0 to 50 Volts scale.

The middle hole of the AC adapter plug is the Positive connection. This is where the Red lead goes.

The outer shield of the plug is the Negative connection. This is where the Black lead goes.

Look on the AC adapter for the OUTPUT VOLTAGE
(Not shouting)

Example:
I'm looking at an AC adapter for an IBM Thinkpad 370, right now.

INPUT: 100V 50-60Hz 130A
OUTPUT: 18V ~~~3.36A

The Output voltage is 18 Volts
The Output Voltage of your AC adapter should be close to this.

On the long term, a power adapter with a bigger amperage can damage battery and battery charger.

Better to get an adapter with same specs as the 65/70W one , or an original replacemant:

1. connect:Both Ground (copper wires) with Green wire
2. Connect Red with Blue and
3. Connect White with Yellow
This will give Stereo Output.

I am showing the AC adpater specifications as:
Input Voltage Range: AC 100V - 240V
Output Voltage: DC 19.5V
Output Current: 4.62A
Power: 90 Watt
Does your adapter meet those specifications?
Although I am a proponent of Targus products, possibly purchasing an OEM adapter may solve the problem. We have successfully purchased ones available from reputible vendors on eBay at a discount.
Have you checked to always show the battery status in the system tray so that you can verify when the AC adapter is actually charging versus an intermittent connection or malfunctioning power socket?
