Zeus- that's good news. BTW- what battery are you using?
If you're using anything like a maintainence free battery or OPTIMA be sure to read, "Car Batteries Are Not 12 Volts " at: http://www.landiss.com/battery.htm
In short, it explains why 13.2 or 13.7 VDC may not be enough for certain types of batteries.
