Just got a new 08 3500 lmm allison 4x4 with dump and 9.5 extreme V fisher plow. When the truck is cold ( below freezing ) and I start it the lights dim 2 or 3 times per second.
Do the glow plugs cycle after the engine starts for a couple of minutes?? My dodge cummins does the same thing just much slower cycle times. After it warms up it is fine.
