OK if you do have a charging problem it looks like undercharging or it would probably have cooked the battery by now.One further check you can do is alternator output.With the meter on AC check the three yellow wires that come from the engine (alternator)to the regulator.Disconnect these at the block connector at the reg,start the engine and measure the output across each of the wires,That is---1 and 2,then 2 and 3,then 1 and 3.You should get a similar reading for each and somewhere round about 70 volts.If one result is significantly lower then the alternator is duff.
