I have a 06 Freightliner m2 with a cat c7. Tried to start it

Customer Question

I have a 06 Freightliner m2 with a cat c7. Tried to start it this morning and it started then I turned on the head lights and the truck shut off. Now it will crank but not start and I noticed the head lights still do not come on and the instrument cluster gauges do not perform the sweep when you turn on the key. I checked all the fuses and battery connections. The truck cranks strong.
