Is there sensitivity to the location of crankcase grounding? I have two independent straps, both B&C supplied, one from the crankcase to the mount (although I don’t see the need, but all the cool kids have one) and one from the crankcase directly to the battery. The battery negative has a strap directly to the firewall/chassis ground block on the firewall. The two crankcase straps come off the same otherwise unused an4 bolt on the RHS (1-3) of the crankcase. Battery is a PC680, about 1.5 years old. Alternator puts out a robust 14.7 volts. It never spun with gusto, but started. I have changed to a lighter prop and ‘never with gusto’ has become ‘charge before trying if cold’. I’m wondering if any meaningful resistance exists between the left and right side of the crankcase? I have a hard time thinking there would be, but before I start digging into diagnostics, I thought it would be good to ask. As a side note, I have no alternator or ignition noise issues.
