ML320 Starter clicking once: No Ground?

9124 Views 15 Replies 6 Participants Last post by  loclark757
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...

The power goes to the starter first from the wire hooked to the alternator or the small wire on the solenoid?:confused:
Positive wire from battery goes to alternator then to solenoid. The other solenoid pole is start signal (negative) given by your key start signal. Maybe take a look at attached diagram and mark down what wire are you talking about in case above does not answer your question.
