Re: [alfa] Elizabeth's battery

["Dean W. Cains" <dwc@xxxxxx>]

Hi Tess:

As I said, it's my contention that the batteries aren't ever taking a full 
charge.  Measure the voltage across the battery terminals after a short 
drive and rest.  If you're not seeing 12.70 volts, the battery isn't fully 
charged, and that applies to Alfa's, Porsche's, Audi's, etc.  You might 
also disconnect one lead from the battery, insert an accurate meter, and 
look for a current drain of less than 20mA.  If the current drain is 
higher, something in the car is drawing it.  Might be the radio, or 
amplifier, alarm system, etc.  You can track such a drain down by pulling 
and replacing fuses one by one, and seeing which pulled fuse causes the 
current flow to drop.  Something on that fuse's circuit will be 
responsible.  Even a small current drain, off a less than fully charged 
battery, will result in a no-start condition.
