After dealing with a minor battery issue in my ML55 last week, I thought my starting problems were at an end, Until today. Since the battery was replaced it's been starting flawlessly. I drove it to my shop today and it sat for about 5 hours. When I attempted to start it, it cranked maybe one quarter of a revolution then nothing...

I figured the battery was dead again from something draining it but i checked it and it was at 12.7V. I then tried jump starting it and still no go. What's weird is that the solenoid is making no engaging clunk at all. Absolutely no sound from the starter, however, every other electrical system is working fine.

I'd find it hard to believe the starter just "burned out" but I guess it could happen. The starter seemed to work flawlessly up to this afternoon. Also, I did get under the vehicle and bang the starter with a hammer to see if that made it feel better, but no luck.....

Is there any thing else I should be checking before I just pull the starter?

Thanks!
Adam
