Now that I'm finally getting some time on the boat I discovered the charger is a Dual bank 20amp fully distributed Pro Sport 20. I'm not finding anything between the charger and battery that would signal back the charge status...but I don't know exactly what to look for. I'll do research on this particular charger tomorrow. I need to find out if the charger is run through the battery selector switch but I'm betting not because it is on the port side of the cabin near the AC/DC control panel, and everything else (batteries and charger, inverter) is starboard. I can test that tomorrow too. I was planning on leaving shore power attached through the winter for the dehumidifier and heater. I could disconnect the battery charger if discharging isn't a likely issue over the eight months I'll be gone.

It's right in the manual. That bank is way too large for a PS 20 we've seen piles of them burned up from long bulk times...

Most marinas will not allow unattended electrical heaters left on. 

I find it bizarre Promariner would say the PS20 was not suitable for your intended use. Thousands of them are installed on boats with bigger battery banks and loads with no issues.

batteries are heavily sulfated...

What's the existing charger?

Rule #1 start with a quality charger. The Victron IP22  to IP67's are almost impossible to beat..You fail to mention climate, in water or out for storage?

If I get to the point where I can ship I will keep you guys in mind. My left arm/hand are still paralyzed so I cannot ship..

I figured I would post this here first. Years ago Leece-Neville discontinued these kits which put a real damper on our alternator business.We wound up scouring the globe to find any that were still in stock. We re-imported 400+/- from Europe $$$. Finally after two years of begging and pleading they did one last production run of 625 for us before they destroyed the machine that built them.

I have 5 cases of 25 each left. Our landed cost on these was $44.12, I would let them go at cost provided the buyer agrees to not sell them to buyers who don't have a genuine Leece Neville alternator (a contract we had to sign with LN to get these made for us).. If anyone wants to buy the whole lot you can sell them for good money as these are the only ones left in existence. I do not have the capability to sell these one at a time so please don't ask.






I would prefer a local pick up in Maine if possible..

@S/V S

Here is one L-N bulletin on the mod, although Rod's write-up is much clearer/prettier.

Different model, but basically here's what it'll look like under the gasket.  I'm wondering if using a Dremel it could be de-potted so as to provide more working space to bring the two field wires to the outside?

  Thanks so much for the help and pictures. I ordered the 105 amp unit from Catalina direct today. It's back ordered 4 or 5 weeks. I thought if I can't afford the regulator yet I could run the charging battery through my dc to dc Victron Charger and  at least 3 stage charge my house bank and limit my draw from the house bank to 30 amps maybe keeping the alternator cool enough. Any words of wisdom.

Do Yourself a favor and cancel that order. C/D is selling elcheapo Chinese  clones and they perform horribly. Once you have cancelled the order buy a genuine Leece-Neville from a legit Leece-Neville dealer such as ASE Supply...

Slow but steady...

It looks like a perfect weekend to head up to the mountain to me..

It is a newly installed Leece Neville 3 wire  type.

Assume wires are ok

Going to need a model #....

Guys : FYI, Duracell make a 105 AH AGM battery.  I've seen them at Sams Club and Batteries Plus!!

A thought

East Penn simply licenses the Duracell name. Those are nothing more than East Penn / Deka AGM's with a different sticker. They are the identical batteries as sold at Batteries Plus, NAPA, West Marine etc... They are not a good choice for a battery that will be deep cycled... We will only install those AGM's as starting batteries.

I'm currently in the process of replacing 4x 6v 175ah (4x 62 lbs = 248 lbs) Powertron's (Trojan) with a single 300ah Lithium (72lbs). This is in conjunction with 2x 200w solar, and a 3000w inverter charger. Looking to be off-grid capable for a 10 days to couple weeks. I guess water will be our Achilles heel, but we can dinghy for that.

Be sure that battery meets ABYC, most do not, and definitely be sure the BMS can handle a 3kW inverter plus the surge.. Also be sure you fully understand how to deal with a BMS load dump.. Lot of sleazy LiFePO4 vendors out there will tell you these are "drop-in" replacements...

[is enforcable]

To say "the Coast Guard has its own requirements and ABYC isn't one of them" is misleading at best.

au contraire, Rod.  That statement was 100% correct.

Ken,

This will be my last response to you.

One example is ABYC A-16 navigation light certifications. ABYC A-16 is enforceable under the CFR. Why? because the Feds simply adopted (incorporated by reference) ABYC A-16 as part of the CFR requirement. This makes ABYC A-16 part of Federal law and enforceable by the Government standards.. The CFR also adopts many other standards not enforceable by law on their own such as SAE, NFPA, UL and others.

The CG DOES NOT enforce ABYC.  Period.

In the example above ABYC A-16 is fully enforceable by law under the CFR because it is incorporated into the CFR.

is there a CFR citation that states that boaters must follow any ABYC standard or that vessels must comply with any ABYC standard?

Not at all what I said. However boaters should always try and follow the ABYC guidelines when doing work on their boats. I say this not only as a boat owner, marine electrician, a member of the ABYC hull piping, electrical and Li-Ion PTC's at ABYC, but also as an expert witness in this field. 

ABYC is a voluntary "trade group" standard.

Yes, it is. 

That is unlike say, when a state or federal code states that an oil storage tank SHALL be inspected according to standard NFPA # xyz.
In that case, the trade group standard is enforcable.  That's not the case here.

It is when the Federal Government adopts/incorporates ABYC standards, or parts of them, into the CFR as in the example above. ABYC A-16 is not the only ABYC standard that has been incorporated by reference into the CFR.

The coast guard has its own requirements and abyc isn't one of them it requires manufacturers to follow.

The CFR/USGC requirements are derived in-part from the ABYC standards with some minor tweaks here and there. The USCG is directly involved in the ABYC standards development and the ABYC in aiding the USCG on the CFR standards where applicable.. There is a USCG representative in attendance at nearly every one of the PTC meetings. To say "the Coast Guard has its own requirements and ABYC isn't one of them" is an odd statement as they work in concert on a lot of it..

[an alternative means of grounding the shaft must be provided]

The ABYC standards are very clear on the use of flexible couplings:

"6.5.5.2 If a non-conductive flexible coupling is used, an alternative means of grounding the shaft must be provided."
