Need wiring diagrams for 2007 S550

This car has been in the shop more than it has been on the road. The current starting problem appears to have occurred four times in 16 months and each time a repair shop has replaced numerous parts without correcting the problem.

There appears to be a short or a bad connection somewhere in the electrical system. Both batteries have been replaced twice and the starter and all computers have been replaced once. The car shows multiple errors on the scanner. Twice it would not even crank but the starter solenoid was getting a spark, but not enough to engage the bendix.

It has been in the shop three weeks this last time and they have removed and reinstalled batteries and computers. I think if we get wiring diagrams and trace the current to the components in error and then back to their supply we may find the problem.

And the car and I are in the United Arab Emirates.

thanks!

Turn down the lamb roaster and do a google search as there are thousands of sites with wiring diagrams or install a bootleg copy of MB WIS
