Hi to all,

I was working on the charging of the alternator, because I found the charging being too low.  Took the alt. out and took it to the store for checking.  It passed with almost 14 volts.  Great.  I put it back in the car and got 11.98 volts at the battery, at the alt. same.  Shut the car down and the battery is back to 12.4 volts.  

I can’t think of anything that I can look at.  The only thing happened in the near past is that a radio was installed by a shop.  

Anyone?
