RE high idle

[Mark Zvolanek <mzvolane@sydney.ipex.com.au>]

Gday again
I was told by many to check my battery, as it may be causing high idle.
Well I did and these are the results.

Battery voltage without the engine running is 12.7V, this battery is   
about 1 month old.

"No load" - NO electrical appliances switched on.
"Load" - lights on high beam and fog lights both on.

With both battery terminals connected and engine running
no load 13.7V (@800rpm) 13.7V(@2000rpm)
load 13.5V (@800rpm) 13.4V(@2000rpm)

With negative battery terminal disconnected and engine running
no load 13.8V(@800rpm) 13.7V(@2000rpm)
load  13.3V(@800rpm) 13.2V(@2000rpm)

What would these results say about the condition of my battery,   
alternator and regulator?

Thanks
