Use a multimeter across the battery, should read around 12.4 volts without the engine running and around 14.4+ volts with the engine running. What wattage are the bulbs in your spots?

With full beams and 4 spots the alternator should be putting out enough power as that is less than a 30amp drain and the stock alt has a 45amp output.

It might be charging....a bit; just enough to keep the warning light off.

Or the warning light might be dead too.
There's three ways of doing things:

The right way,
The wrong way
And my way, which is like the wrong way but faster.
