Question about Volkswagen Golf
The battery light being on means that the alternator is not charging properly and the car is getting it's power from the battery. The car will eventually run the battery down and die again. You will need to replace the alternator.

Couple of things to check, first this may be nothing more than a belt that has loosened or stretched after the install.There should only be about a quarter of an inch stretch in the belt between pulleys. Caution - only check with engine stopped!!! The alternator causes a strong resistance when it is producing electric power, so slippage is to be checked first. Second, if the battery light comes on and off; it maybe acting in error. Get a multi-meter and check the battery voltage with car and ignition shut off. With the meter set on 12volt bat, place the black probe on the negative side of battery or ground and the red probe on the positive side of battery. If you get a reading of 12.66 v the battery is being charged and is full. If you get 12.45 you have a 50% charged battery. If less the alternator wiring needs further checking into as there maybe issues with wiring or the alternator itself. Hope this helps.

Battery 'charging' warning light usually only indicates if your battery is being charged as it will switch itself off only when adequate charging current is flowing (e.g. usually after your engine has started). To restate super_guy advise: 1) Check if battery is OK: engine off and cold (e.g. to let battery settle as we want to check it), use multimeter to measure voltage which should show around 12v - if it shows 10v or less, at least of of the cell maybe shorted or sulfated and not charging. With engine off, putting the headlights on for a couple minutes then off could help prevent wrong reading. 2) With engine running, the measure voltage at the battery terminal should show at least 13.8v. Anything above 14v may indicate that your car alternator regulator is faulty, 3) If your battery and the charging system appears OK, then the problem may simply be dirty connections to the alternator (usually a three pins connector): I would actually try to clean the alternator connections first by using some fine emery paper/point file or simply pulling and re-interting the alterantor plug a few times (cleanig by friction that is).

Testimonial: "very good advice .alternator was faulty"
SOURCE: red battery light on for
I assume you checked the battery cables and cleaned the connections and made sure they are connected tightly
Next I would check the fuse... may need to be replaced even if it looks "ok"
If so and the light is still on
Then the battery indicator lightbulb behind the instrument panel may be bad.
