On my 2007 cummings I keep seeing a symble on the dash that looks like a coil wire. It goes off after I start the engine. The needle on the altenator drops down to about 8 amps and then comes back up to over 14 amps. any idea?

Is it the only lamp illuminated before you start the engine? (There should be a pre-start key position where all the dash lamps can be visually tested; i.e., the lamp-test position)
 
No "check engine" lamp illumination after starting?
 
I've never owned a diesel. Could the symbol represent glow plugs, indicating malfunction of one or more glow plugs? (Since it's winter, thought that might be a glowplug symbol.)
 
The 8A to 14A change in alternator current might be related to an intermittent glowplug or intermittent connection to a glow plug.

Here's another idea. Try the Dodge Cummins Diesel Forum at dodgeforums.com. You can search the forum without logging in.

Probably your vehicle just did not automatically reset or clear. Try auto zone/oreilly/etc to reset code.

It's the glow plug indicator lamp. Turn the ignition key to the ON position, and wait for the symbol to go out (the glow plugs are warm). Then START the vehicle. You should not see the symbol again while it's running.
 In the diesels I operate for the Highway Authority, they all have this symbol, including the front end loaders. The FORDS say "WAIT TO START"

19. Wait To Start Indicator
The Wait To Start Indicator will illuminate when
the ignition key is first turned to the ON position.
Wait until theWait To Start Indicator turns OFF then start
the vehicle.

You gottabe kidding me... You bought a diesel but obviously don't know how they work... Diesels use glowplugs not spark plugs... The glow plug needs to warm up before starting e engine to prevent misfires or damage. That is what the Coil light is... You need to have the key in the on position till that light goes out before starting the truck.... Especially in cold weather...

The Cummins diesel in Rams does not use glow plugs. Cummins uses an electric grid heater (similar to the heating elements inside a toaster) to warm the air before entering the intake manifold. The grid heater continues to cycle for up to three minutes after the engine is started or until the truck is put in gear and driven. This cycling causes the electrical "surging" that can be observed by the voltmeter and the repetitive dimming of lights.
