So yesterday I had the cowling off and was studying how the Reiff Pre-heater installation might be done on the O-360.
I noticed in the instructions that they grounded the wiring harness to the crankcase bolt that also has the engine lift ring.
I really would rather not screw around with crankcase bolts if I didn't have to.
But I noticed a threaded location just below that lift ring, in between the two cylinders.:
The Reiff harness is laying on the top of the crankcase and is threaded through the lift ring.
What is that threaded location for? There's one on both sides of the engine.
Also, at the right of the photo is a support for the forward part of the baffling. Looks like aluminium. The Reiff harness connectors are in front of it. Is that conductive enough to serve as an engine ground?
Thanks!
