These numbers are bad. Even at idle the voltage should never go below 
12 V, but the correct way to check is at medium RPMs, where the 
voltage should go above 13.5 V. Ideally, at the battery it should be 
14.1 - 14.4 V at medium RPM.

Do you have my charging system faq? If so, have you run thru it?
