Oh ok, so you need to check all of the charging system, fuses, wiring for shorts or breaks or bad connections, main switch if the charging goes through it, the battery condition, the stator resistance and/or output, and the regulator.
First test will be to check if it is charging, by putting a volt meter across the battery terminals and seeing what the voltage is, it should be close to 12.6 volts, then start the engine and the voltage should slowly rise to between 13.6 and 14.7 approx, and it shouldn't go over about 14.7..
