Hobbs Meter

I think the ones I’ve installed/replaced have all been. But it’s been a while so I could be wrong.

Side note, whenever I installed an air Hobbs, I would use an in-line fuse behind the panel for circuit protection. Want to disable the Hobbs? Great, hope you enjoy flying with the master off.
On our duchess it used the right engine oil pressure, so you could fly around single engine all day for free ;)
