What is this grounding wire for and where does it ground to? I raised the motor in the driveway last night and it started to smoke and melt the cover plate. Plus it would zap the battery pretty quick and the motor won't start, just spins the starter.
Motor is a 1989 Mercury XR4 150 hp serial #:0C137920
Just recently had the lower unit replaced so not sure if this had anything to do with it.
