New to the diesel world, and lookin for info.
 

Hello im one of the newbies and naturally i have questions. I have owned two dodge rams one with a 4.7 and one with the 5.7 hemi and loved both so i decided to up grade. I recently bought a 2005 with the 5.9 cummins w/101,00 miles, but not sure if what the truck is doing is normal or not. When i start it cold the volt meter reads below normal and if the headlights are on they dim and brighten several times until the volt meter reads normal. Also if i depress the accelorator and release it the engine continues to gain rpms and while deaccelorating the rpms pulsate until idle. Is this normal for a diesel or do i have a few problems ? Any info would be helpful, Thanks.

Perfectly normal on both counts.

The first thing is your gride heaters. They fucntion when the truck is cold and draw a lot of amps (100+) to heat the incoming air before it hits the combustion chamber.

The second thing is your high idle which you want to use anytime the truck is idleing for an exntended period of time (5+ minutes).

Read your owners manual - should all be in there.

Ok thanks for the info was hopen it was all normal. Unfortunitally it didnt come with the manual workin on gettin one though.

Yea my lights will be dimming then re-brightening at cold start ups several times aswell...anyways welcome and good luck with your Cummins
