ML320 Starter clicking once: No Ground?

It's been about a month now since my ML finally quit starting. All ground wires are good. On my fourth starter of the year. It's a rebuilt one. Battery is good.

It seems the starter will work out of the vehicle but, once its installed I just get a single clicking sound once the key is turned...

Hooked it straight up to a jumper box with no change. Surprised it wouldn't work even then.

There's a TSB about the ECU going bad which is what I'm starting to lean towards.

I've even tried a pushbutton start and that does the same as the key.
I'll take a closer look at the positive cable in the A.M. and re-test the power side
It was the #23 wire from the starter to the alternator! It's a little over a foot long. Pretty corroded on both ends and the copper was all green. I used to live at the beach oceanside. Damn salt air!

I just cleaned the positive cable and post. As good as new.

The cable cost 6 bucks from pep boys...:thumbsup:
The power goes to the starter first from the wire hooked to the alternator or the small wire on the solenoid?:confused:
Yes, thank you. I fixed it.

Just curious about the circuit. I get it now.

Those diagrams sure came in handy...:thumbsup:
