My Merc 5.0 MPI won't start. Battery is good, as I just replaced it and getting 12 volts to the slave solenoid, get 8 volts coming out of slave on the red/yellow wire when I turn the ignition. I put on a new solenoid and it did the same - one click when I turn the key. I have 12V at the starter on the main post, and no stray voltage on the secondary post. I'm still thinking its the starter. Can I jump the starter somehow straight from the battery? I'm concerned too It might be the breaker mounted adjacent to slave solenoid. And furthermore if I can determine the starter is bad, how in the world can I replace it myself? Its buried lower rear starboard!
