Headlights dimming when engine is under load.
Happens when I am driving down the road and I give her a litlle go pedal. More noticable in the snow becuase the headlights reflect off of it real well. No other electrical problems. They dim initially and come back to normal.
New batts this summer. (Motorcraft)
terminals are clean.
Alternator 1 Year old. (New Autozone)
No trouble starting in cold temps (10 deg.)
What should I be checking with the multi meter? or Should I not worry about it.

Any way to run the truck with a real voltmeter and see what they are doing? I know all my truck has is a dummy battery light. So I have one of these http://www.xantrex.com/web/id/97/p/1/pt/1/product.asp but i dont measure current on the front batteries. I have two 100 ah batteries in the bed and watch their current and voltage from the link 20, and the front batteries voltage with it. But you can do it with any volt meter.
