Alternator regulation Amel 54
Dear forum,
I'm in the process of extending the charging system for out batteries as preparation for Solar panels and ultimately a nice set of Lithium batteries. Currently I'm looking at the grey box that sits at the rear wall of the engine room, above the Volvo engine (see attachment). In this box there is an (Alpha Pro) alternator regulator for the 110A/24 Volt alternator, two relays and a bridge rectifier. It must have something to do with the activation of the 24V charging circuit but there are numerous 12 Volt wires as well. Before re-inventing the wheel, did anyone already reverse-engineered this box? I talked to Bill Rouse about this thing and he is guessing it has something to do with the excitement of the field-wires in one of the alternators. I was also thinking it has to do with delaying the 24 Volt charging circuit until the engine is running properly as the 24V alternator creates substantial drag, even at idle. What mystifies me most is the rectifier. Are they using a part of the 12 Volt Alternator to sense the state of the engine? Thanks for your insights Arno Luijten SV Luna, A54,121

Sounds good, Pat. Magnia Friday night and you had put 6:30 on the table.
Seems a number of us will be on Back Creek so let’s see if there is interest in dinner at Davis’ on Thursday evening.

Re: C-Drive vs Linecutter
John Clark
Tim, I agree with Bill. Not sure of the core foundational construction of the c-drive but I would bet a dollar that for that drain port the seal is the o-ring. I would replace the o-ring and liberally goop the nut with sealant. The most likely source of water in the oil is the shaft seals.... especially if they are old. I change mine every haul out(2-3 years) as the previous owners coached me to do and have not had any issues. It is fairly simple to do just be patient, clean the area and don't force anything. I used the heavy weight oil last time with no problems. My SM is an early model but has the late model c-drive (and TMD-22) thanks to previous owner repower at La Rochelle in 2002....so it should be the same as yours. Regards,.

Re: C-Drive vs Linecutter
Thanks Bill, 80W90 it will be.
I was intending to use Silicon grease on both the O ring and the lip seals (since they contain rubber). Are you suggesting using some other waterproof grease on the lip seals? Most of the waterproof grease products I’ve seen appear to be either Lithium based, which isn’t good for rubber, or have unspecified base material (probably oil based, again not good for rubber). Best regards Dean SY Stella A54-154

Re: C-Drive vs Linecutter
Dean, A few years ago Amel changed the spec for all C-Drives to 80-90 gear oil. I always used waterproof grease on the lip seals, but always used silicone grease on any O ring. A crop-dusting helicopter pilot once told me that O ring failure is a very important issue with helicopters and he and his friends insisted on Trident Silicone Grease, only found in dive shops and also on Amazon.

Re: C-Drive vs Linecutter
Hi All,
Thanks to everyone for the guidance. I found a source for the Dowty/ Bonded Seal washers, and have renewed the O-ring. Could not get the V bolt to align with 1 or 2 Dowty washers, and 3 was too many. So have resorted to mastic like others to complete the seal. Not very happy with that solution, but it seems to be accepted method so we’ll see how it goes. Now part way through replacing the bushing and lip seals, so will be able to fill the transmission with oil before wintering. A little tricky finding ‘silicon’ grease around here on a Sunday :-) One final question on this little project. I remember having previously seen discussion about which oil to use. I have both 15W40 engine oil and 80W90 gear oil. Which should I use? Many thanks Dean SY Stella A54-154

Re: Lift the Perkins 4236 on a Mango
Frederic F
Thank you very much to all for the fast responses. The big nuts of the engine mounting are already open, so this part shouldn't be a problem anymore. I think we will try the timber solution to prevent any damage of the boom.
Hopefully everythink works out well. Best, Family Fießer Mango #14

Re: Converting my Amel 54 to lithium batteries: what I did, what I like and what I don't like (after one year of full time live aboard use)
Scott SV Tengah
FYI it turns out my Quattro is mounted vertically in the engine room, so airflow is as Victron recommends. That is probably why it doesn't suffer any reduced charging output or inverter output after extended use.
See attached. I modified the intake air that Amel provided for the old Dolphin chargers a bit so that it feeds air to both the Skylla and the Quattro. The Skylla is mounted sideways, but again, I have never experienced reduced output from it. That's probably because it's only running at most 2 hours at a time and that's if the battery bank starts out empty, which never occurs for me. -- Scott 2007 A54 #69 SV Tengah http://www.svtengah.com

Re: C-Drive vs Linecutter
Danny and Yvonne SIMMS
Hi Tim, Amel recommend replacing the 3 c drive shaft seals and the wearing bearing every 1000hrs. Most of us do the change biannually regardless of hours. It is an easy and relatively low cost preventative maintenance item done conveniently at a programmed haul out. If yours are over 4 years I would place that very high on the probability scale for water ingress. Both the seals and the wearing bearing should be replaced. I wont express an opinion on the sealing of the plug. Regards Danny SM 299 Ocean Pearl

Re: C-Drive vs Linecutter
It looks to me that there is some sort of O ring at the top of the threaded portion. It is black. What is that? I would guess the chance of having water inside the C-Drive 4 years beyond service date is very high. Regarding the drain plug area, is the GRP also cracked? See below: I am sure it must be an illusion, but the mark in the metal appears to be raised. I am going to assume that it is an indention. The shell of the C-Drive is made of GRP, and there are metal inserts that support bearing connection points, seal points, and this particular drain plug hole. I think you need some expert advice from someone knowledgeable of the manufacturing process of the C-Drive in order to find the best solution. I will offer a temporary recommendation, without any direct knowledge of the C-Drive manufacturing process: Since there is not any significant positive or negative pressure inside the C-Drive, I would be tempted to use Silicone RTV to fill the indentation of that scratch and also on the O Ring...at least until someone can offer an expert solution.
