The ammeter in my TD has always read around plus 15 amps at crusing speed.  
This amount of constant charging didn't seem right to me, so I hooked up a 
voltmeter and discovered the generator was pumping up the battery to 16 
volts. This sounds too high, but the shop manual indicates the correct 
setting is 15.8 to 16.4 volts at room temperature. The rule of thumb in EE 
circles is 14 volts for charging a car battery. Does anyone know why MG set 
the charging voltage so high? Does anyone else get +15 amp readings on the 
ammeter all the time? (Yes, the battery is losing water faster than it 
should.)
