 This may be a basic question for  the electrical gurus out there this is my 
first "problem" so bear with me. I have 150 hrs on my ES with a Cont. 
IO-360-ES w/ concord R.G.12 volt batt. and the factory recommended NAPA brand 
VR-154 voltage regulator (i.e., solid state and built and looks like a tank). 
While in flight recently got a low voltage alert on the VM-1000 (specifically 
12.8 volts). The ammeter (with the sensor on the alt. out wire) was 
indicating a load that would increase appropriately
(i.e., with activation of pitot heat, lights, etc. the indicated amperage 
output increased proportionally). My first action was to recycle the master 
(no affect). after 8 -10 minutes flying back home, I noted the voltage was 
remaining constant (i.e., no batt drain) and no amperage changes. When on the 
ground and engine off, the batt. voltage reads 12.2 volts and, after cooling 
several hrs, restarting the engine, the voltage indicated 13.9 -14.0 volts 
(which would usually read 14.3 -14.4 volts). I'm thinking the regulator is 
starting to crap out, but am I missing something else ?

 Thanks in advance,
