Hi Jim; about your comment ;
""I was told not to replace mine, too many failures.
Jim ""
Why ? What " modern " component can replace it?
Hi Marcham, yes, but generally speaking; greater are better......but I don`t know if in this particular case that´s true
Thanks both !!

I talked to the Hunter Sailboat Electrician that actually wired my boat.

I asked him what is this thing [pictured in my post #13 above ]. He explained the function.
It was his comment , I posted here.

and the advice was to put what thing in place of the relay ? or in other words, what did you put on your boat ?

nothing.
My boat has a Generator that can charge my House Batteries.

There are substitutes called ACR, which I don't use.

I like to keep original the boat Unless a part or component appears that actually does the job better. I think that the Cole Hersee relay that is the original part of the boat now come from china .....and that could be a quality issue. about the Automatic Chargin Relays ACR ( electronics) there is a lot outthere to chose.....and I am totally lost which one to choose ......
thanks !!

The only small challenge when switching from a relay to an ACR, is the ACR will be active anytime the start battery voltage is above the ACR activation voltage. So if you have separate shore power chargers for the start and house bank, that will be defeated, as the start batt charger current will now flow into the house batt.

If you are making no other changes to the vessel electrical system, I'd stick with a relay.

Assuming you have the stock alternator, a 100 Amp CONTINUOUS DUTY solenoid relay should be plenty. Cost will be around USD60.

Another option is the BEP DVSR. You cut the short red wire and use the ignition 12V that you already have at the solenoid to activate the ACR (DVSR) only when the ignition is active.
