On a class C E450 the Trombetta is located under the coolant reservoir in the driver's side rear of the engine compartment. I'm not sure if it's in a similar location on the ACE.
When I push the Emergency Start switch I do hear the click of the Trombetta energizing. It also energizes a few seconds after starting the engine so that the alternator charges the house batteries.
My Trombetta failed and was not allowing the alternator to charge the house batteries. The symptoms were that the house batteries were not charging and I was getting a low voltage error on the levelers. I thought the batteries were going bad, but new batteries didn't fix the low voltage error. The Trombetta was energizing, but there was a voltage difference between the input and output terminals. This difference shouldn't be more than about 0.2 volts.
I'm not sure how much of this info is relevant to your problem, but hopefully some of the infowill help you troubleshoot your issue.
