Re: [Amel Yacht Owners] Generator exhaust
Gently, and with all due respect, I would like to suggest to you that it would be a good idea to have someone very knowledgeable with Amel boats and their unique systems, in their entirety, spend some time with you on your boat. Part of the excellence of Amel boats is in the unconventional way Amel does several things that produce more satisfactory overall results than conventional practice.toggle quoted messageShow quoted text
Bill Rouse, when he asked you if you would install an isolated ground system generator, was talking about the big picture regarding the Amel 12 and 24 volt DC electrical system. Isolated ground, also described as full earth return and an isolated negative electrical system is when all of the DC energy comes out of the battery, to the device it powers, and then directly back to the battery bank via a closed loop system. This is precisely the same system used on most metal boats world wide. It prevents a whole bunch of electrical and galvanic problems and makes this DC system better for all the elements of the entire system.
If you install a 240 volt AC genset with a 12 volt DC conventional ground system for starting and the alternator for starting battery recharging, you will have electrical and galvanic trouble until this situation is changed. The sad fact is a majority of marine electrical contractors and/or installers think this not “a big deal” and pay little heed to the difference between conventional ground and isolated negative ground as it pertains to the DC electrical system.
If you dig deep into the incredible wealth of information that has been presented in this group, you will find many admonishments not to change anything on your Amel until you are absolutely familiar with what you intend to change.
Don’t be hesitant to ask for help if you are not 101% sure that the changes you entertain will produce positive results.
Good luck with your new to you Amel and be sure to have fun with it.
