Hobbs Wiring

My Hobbs meter isn’t moving. Does Hobbs connect up with oil pressure or straight to the master bus?

I've seen it done both ways.  Mine is wired through an oil pressure switch.  When the engine is running, so is the Hobbs.

Easy stuff first:
Try connecting a 9 volt battery to the Hobbs meter directly using alligator clips. Wait 6 minutes and see if it turns...

Good idea, I'll try that. Now that I think about it (and now six states away from the plane), the main bus isn't that hard to get to.
