Good Day,
I will be installing a new Raymarine chartplotter to replace our old Raytheon 398 GPS/LORAN, and the installation instructions recommend grounding one of the wiring harness leads to the boats RF grounding point. Can anyone advise me where this RF grounding point is located.
Thanks.

Shower sump is OOC. Pump and float switch both test OK. Tested wiring at the shower sump with a voltmeter but no power. Sump circuit breaker on main battery panel is IN. I did a cursory check of the wiring to the DC bus bars in the engine compartment and all look OK.
Any troubleshooting help...
