Thanks for the pointer to P 97.203/209 Phil. Good lesson in that. Look
around so to speak. (you'd think I'd have learned'd by now'd)
For sure. Yes. I had looked at P 97.17 too. I was curious because of
David B's original post. I figured the location of the ground
shouldn't have changed after all these years.
And yes. FTW. Crazy details on these Aging Vehicles. Water ingress.
Maybe you could create some kind of permanent water egress. But I
digress. Maybe we could all install some kind of huge grounding bolt
in the middle of the floor and run all the grounds to that. It
wouldn't be in the way. Might make a nice seat too.
;)
Neil.
