R170 SLK supercharger resistance/voltage/current?
 

Ok, I want to do a bench test for the supercharger clutch. First of all, I measured the resistance across the two pins and got 3.6 Ohm. Is it me or that is way too low?

Second, I applied 12V (connected to my battery) and no click.

Shorted?

With an ammeter connected the clutch should draw between 2.5-4.5 A

Are you getting a code for the clutch?

3.5 ohms circuit at 14V is 4 amps - which sounds correct as the doc..
