Our boat has both mains directly connected to the start battery. If there is an issue the only way to remove the 12v from the starter is to disconnect at the battery. Not a great idea to have to crawl into the ER with a runaway starter or an electrical fire to unscrew the bolt holding the cable to the battery. Also the 12v cable to the starter is "hot" all the time.
So the options I have been bouncing around are:
1. Put a manual disconnect "1-all-2-off" switch outside the ER and run LONG and LARGE cables to the switch so that I can energize or de-energize the mains from a safe location. (Not on my knees in the ER)
2. Install Blue Sea Remote Switches i.e. https://www.bluesea.com/products/cat...ttery_Switches
in the ER and have a switch on the dash that would operate the remote switch.
The first option involves a lot of cable and thus expense. The second option seems neater but I wonder if that is a good solution if there is a problem (fire, runaway starter etc)
Anybody gone either route? Any other possible solutions?
