Hi Nick,
You will need an accurate voltage meter.
Set the VOM to DC volts, connect the meter to the poles of the battery
(polarity sensitive). Start the engine and avoid revving the motor, even
for a short moment. Record the reading of the meter. A reading lower
than 12.6 volts usually indicates a weak battery.
Slowly increase the engine speed. The meter reading should increase too,
but will stay steady state at an engine speed somewhere at 1000 rpm.
From then on the reading will stay "locked". It should be 13.8V, +/-
0.5V is acceptable. A voltage too high is NOT good: it will over charge
your battery and wear out bulbs and other equipment!
A voltage regulator is good when the reading hardly reacts to change of
engine speed or to adding power consumers like the heater fan or main
headlights.
If there's voltage drop, it's either a bad wire between the alternator
and battery, a bad alternator, or a bad voltage regulator.
Good luck

Is there any way to check the regulator to find out if it is faulty or
not?

If the generator light is off when the key is in the run position (
before
starting ) then comes on when the engine starts , check the ignition
fuse.
Otherwise , i agree with Brent , check the regulator.

Most likely its the voltage regulator or one of the connections at the
reg.
