Dim Lights Until Accelerator Depressed

I never noticed this until yesterday morning. I started the truck and let it idle for a minute. I turned on the lights and they seemed dim. Then we started to move and things got bright like normal. Is this normal? Weak alternator?

Look closely at your battery connections Jason. The dim lights may have just been from the glow plugs running also.

That is what I am thinking.Dodges will do the same thing when you first crank them.

Ok cool. I probably haven't paid attention to this before yesterday.

The battery terminals are very clean. A few months ago I brushed them all clean with a wire brush and applied a thin coating of dielectric grease on them. I did the same to the terminal clamps. Works great.
