Re: Battery Isolator Cole Hersee

4 Trojan T-105 batteries in series/parallel to make a 12 volt bank is 440 AH.

All charge sources should go to the house bank.

Re: Battery Isolator Cole Hersee

As Maine said in post #5 the Dual Circuit switch you are referring to is designed for and best suited to boats with equal size banks such as small fishing boats. It is not the best choice for boats...

Re: Seacock Replacement - ball valves

Get someone else to hold a stepwrench in the through hull from outside.

Your problem is the reason a flanged, bolt through base is a good idea.

Re: Novice trying to figure out fresh water pressure issue

Pumps always push better than they draw. The pump should not be mounted higher than the tank ideally.

Re: Breaking All the Rules ...

I agree with atoll, polyester resin will not work - another reason is that it doesn't stick to epoxy.

Re: Balmar alt/reg issue - Incorrect Field Voltage

The way I read the post is that you suggest the sense wire should go to start battery then in the next paragraph have alternator output going to the house bank.

Re: Balmar alt/reg issue - Incorrect Field Voltage

The sense wire should be connected to the same battery bank that is receiving the output, the house bank being the best choice as it is the bank most in need.

The start battery can be charged...

Re: Improving on Shore Power Connections

The Smartplug is a huge improvement but not likely to see that on many marina pedestals in my lifetime.

Looks like teak to me. The sole looks to be solid, not veneered.

Re: Help Me Refinish My Cabin Sole- YouTube

If it is epoxy I doubt any remover will remove it. Scraping and sanding - with a good dust mask - is the solution.

Re: Adding a 3rd battery to the bank

PT was referring to 6 volt batteries (golf cart batteries) and in any series/parallel bank of 6 volt batteries you need an even number to achieve 12 volts. They (Fla golf cart batteries) are by far...

Re: 12 Volt Bible for Boats

He might. But I doubt anything could be done about it - it leads back to a site in Russia.

Re: Adding a battery bank

I fail to see any benefit to #4 over #3.

My preference:
Large single house bank - with all charging sources direct to it. Separate start battery charged with ACR, Echo Charge or similar....

Re: 240v Shore Power Connection

That is not an effective solution really. A North American boat can use a 1500 watt water heater, kettle, toaster, etc, all @ 120 volts - all within the 15 amp rating of a typical circuit. By keeping...

Re: 240v Shore Power Connection

Only problem with this theory is that the European equivalent of North America's 30 amp shorepower is 16 amps @ 240 volts. Individual circuits in North America are most often 15 amps @ 120 volts. In...

Re: Adding a battery bank

Not a great idea really. A large battery bank is more efficient than 2 banks half the size both when using power and when charging. The batteries will last longer if in one large bank as well.

As...

Re: Battery Charger Output Amperage

The goal should be to put in as much as the batteries will accept at proper bulk charge voltage (14.8 for Trojans for example) to shorten engine/generator time. No matter what you do the last 15% or...

Re: Battery Charger Output Amperage

While some manufacturers recommend 10% of bank size it isn't the maximum liquid acid batteries will accept. They will accept 20% or so of capacity, for a while at least, in bulk charge.

Re: Solar-Battery Load: Perfect Balance

The Greenline will travel only 20 miles @ 4 knots under electric power. Much longer @ 3 knots. In a reasonable current in my area that would mean travelling backwards, often at more than 3 knots.

Re: Catalina 30 cooling question

There is not any antifreeze as it is a raw water cooled engine.

No separate plumbing to the stuffing box in a Catalina 30.

Re: Solar Panel Wiring Question

It depends on the wire gauge you are using between the controller and the battery bank. The larger the wire the larger the fuse can be. Larger fuses have less voltage drop than smaller fuses so...
