    You will need a electrical diagram of the charging system, then it is a matter of skill and time to find the problem, have you checked the connector at the alternator? You won't need a harness, the problem can be repaired if you just know electrical automotive repair real well.

If you have not measured the voltage across the battery with the engine running, you don't yet know if it is receiving sufficient voltage to charge and you may have a defective regulator instead. You can buy a digital multimeter that will do all any homeowner needs for less than $20 US at electronics shops or auto parts stores.
With the engine running, you should measure at least 13 volts at the battery and it can be as high as ~14.5 volts without damaging anything.
As far as your gauge problem is concerned; I think you have a flaky connector or a ground that has failed. Check under the dashboard for wiring plugs, disconnect all of them, one at a time, and reconnect them several times to 'wipe' the contacts. Auto connectors are incredibly cheap crappola and fail easily.  
I agree with emissionwiz - you don't need a harness but you may need some time.

Battery light stays on after changing battery,alternater & plugin.


Is the system charging? You should have 14.2 14.6 volts at the battery. The charge light is controlled by the alternator internally. If the charging system is working, you could have a bad diode inside the alternator keeping the light on or a short/grounded circuit to the battery light

What you have doesn't sound quite right, nor does the advice you are getting, though I don't think it would cause a short either.
I think the right way depends on what you want the amp gage to measure. If you want it to read the total output of the generator, you have to connect everything in the car to the other side (opposite from the generator wire). On the other hand, if you just want it to measure what current is going to the battery, then you put the accessory wires on the same side as the wire from the generator. I have made 2 diagram below. A volt meter is easy, and you can have both, if you like. A voltmeter just goes straight to the battery terminals if you want to know for sure that you are charging. You can use plain ground and the alternator wire, but then if there is a fusible link from there to the battery you are not always sure the voltage is getting to the battery. Does this all make sense?4603398.jpge9d6f29.jpg

Hello, the battery of my jetta 91 car is suddenly discharged , can you clear the reasons please


There may be a surface discharge. this occurs when the vehicle still draws current from the battery even when the car is off.the problem could have been going on for a while now and the battery just cannot sustain in a charge any more.
most times this occur in the morning when you start. a simple test is to disconnect the battery at night an see of it starts in the morning the battery held its charge and the car is the problem..
Other Reasons:-
the lights was left on
a door was left open
battery not holding charge
no battery water
the alternater not working well to charge the battery

Are you sure the alternator isnt "over" charging? if not, you may have a "loose" connection somewhere with the cables, or a malfunction in the dash cluster. Also, are you positive the battery is forsure good?

First off, add a new ground wire from the engine to the body just for the hell of it. Now clean all the battery cable connetors aat all point and add WD40 afterwards. Also check connectors from dash panel to engine circuits. This is real suspect. WD 40 them also
