Can you tell me what the max voltage of my disco 2 at the battery when the engine is running i have 110amp alternator cheers Dan
 
about 14.5 volts - any more and its fooked.

If the battery voltage goes below 13.5 volts, the voltage regulator sends current to the field terminal and allows the alternator to start charging. Current will then flow into the battery and bring it up to full charge. If the voltage goes above 14.5 volts, the voltage regulator shuts off the current to the field terminal and keeps the battery from overcharging and cooking itself. This is how the voltage regulator controls the alternator output.
