  1. Battery Systems Upgrade

    E32-3 Battery Systems Upgrade

    My big project for the winter was upgrading most of my battery-related systems. Though some of this had long been on the list, the whole lot got moved to the forefront when my old Newmar 25 AC charger died. At about the same time, one of my flooded LA batteries was having trouble holding...

    E26-2 Solar Arch 1/2 finished

    The bases are mounted the side structure are mounted I bent the top tubes and have them mounted temporally I have to weld crossmembers on the top tubes then bolt some cross members to hold the panels. Its coming along.
  3. Fixing the Main DC System Part 3 - Adding Solar

    E35-3 Fixing the Main DC System Part 3 - Adding Solar

    It was clear when we bought the boat that it had been designed to sit at a dock with the shore power charger doing the bulk of the work. Then when offshore, I assume it was all about the 100A alternator. However, we weren't going to be having our boat at a dock, so it was imperative that we...
  4. Fixing the Main DC System Part 2 - The Battery Box

    E35-3 Fixing the Main DC System Part 2 - The Battery Box

    So the first thing to do was trace the wires and figure out what was what. Since MOST of the cable was good Ancor marine wire, my plan was to re-use it, and re-terminate it, using the FTZ power lug crimping tool as found on Marine How To. I did this by using electrical tape, then when I was...

    E35-3 Fixing the Main DC system (up to the panel) Part 1 Discovery

    When we bought Rhumb Ration, one of the issues that I had to fix right away was a comment from the surveyor. The main house batteries were not secured in any manner, neither was the engine battery actually. Three batteries were in the original battery box, just sitting there due to friction...

    E26-2 Solar Arch

    So I'm adding a solar arch on my 26-2 its something to do with a lot of time on my hands. I have a mill and a tig welder to make it less expensive. I'm using 1.5" aluminum tube and making it so I can knock it down without getting to nuts. I just got the bases back from the powder coater and have...

    E32-200 Projects: Voltage, Balls, Bilge, Cold Start

    High Voltage I headed out for a day sail this week and was motoring about 50 yards out of my slip when my remote radio mic on my helm began beeping at me and flashing a “HIGH VOLTAGE” warning. Having blown a fuse in a Standard Horizon head unit during my electronics upgrade, this seemed like a...

    E38 200 Watt Solar Installation on an E-38

    I’ve been studying adding solar for quite a few years and this summer (2020) I finally purchased two 100 watt rigid panels, two MPPT controllers and the necessary wires that connect the panels to the controllers. Along with the modifications to the lifelines to mount the panels I’ve spent about...

  13. Inverting the Cockpit Panel for Visibility, Thelonious II

    E381 Inverting the Cockpit Panel for Visibility, Thelonious II

    On many Ericson models the helmsman can't see the temperature gauge or the tachometer without a swooning, eye-bulging contortion that alarms guests and can cause them to cry out, "Is he all right?" That's because the panel has the ignition, glow-plug and start button on the bottom, and the tach...

    E32-200 Out with the old wiring, notes on Raymarine parts

    One of the marks of good craftsmanship is tight tolerances between materials - pieces of wood, metal ducts, pipes, etc.. It seems that Ericson boats came out of the factory with fairly snug fittings all around. To change around the electronics in my boat, I would need to pull some new wires...

    E32-3 Another Engine Panel Upgrade - Pt. 2

    (Continued from Another Engine Panel Upgrade - Pt. 1): The original black engine panel frame was in pretty good shape. The panel-back has a slight rim around the mounting flange which leaves a shallow void behind the screw holes. I think this is why it often cracks beneath the screws. I...

    Battery Charger Location for E30+ (none ever installed)

    Hello All, I'm back! I sold my E29 last year and recently bought an E30+. She's a real peach but I do have a few questions as I get to know her. One of the oddities that came up after I agreed to purchase her was the lack of a battery charger. The previous owner decided not to install...

    Adding light fixtures - where to get them?

    I've decided I'd like to add an additional light fixture on each side of the boat, and ideally I'd like to keep the same style as I currently have (the "soap bar" style that I think pretty much everyone's boat has) Where can I buy them? Does anybody have any spares?
