Having recently gone to hell and back (like yourself) trying to find the starting problems with my D650, I wonder if this will help. On the 650, under the seat, to the front of the battery are three relays. To the rear of the battery is another relay. I was removing, swapping relays to try to isolate my problem. I can remember though that while removing one of those 4 relays, just the headlights would be on and there would be no other cockpit lights on. The giveaway is when the fuel pump dosen't prime. On the 650 you can both see this (tacho needle goes off the scale) and hear it. If it's the same with the 600, it would be worth checking these relays.
