My husband went to an auto shop in Georgetown and bought the ONLY alternator they had. It is a rebuilt Delco we think. It has 3 wires. How do we wire this in? This...

    Sterling regulator

    I read this recent article by Niger Calder about Sterling regulators. One of the big mags. Who would have thought? Essence: don't go fancy on alternators or batteries, use to the MAX what you have. As usual great writing. I did a bit of searching in the archives, but nothing popped out...

    alternator wiring

    I was trolling thru an alternator thread from a couple years ago and found a post by Maine Sail which showed the back of a 90 amp Leece/Neville alternator. (I'd link to it, but for some reason I can't copy or paste from the website field). I expected to see a wire capable of carrying 90 amps of...

    Stock Alternator delayed startup?

    This is one area that, to this day, evades me... :) I noticed this season (may have happened earlier) that the factory alternator upon engine start in fast idle does not deliver current to the batteries. Link10 shows the batteries at resting voltage with current coming OUT (fuel pump). This...

    Alternator mounting bracket mod

    What is it? I've seen it mentioned in several places. Is it something I should do on my M-18? I understand that the stock belt will not fit with this mod.

    Converting An Alternator To External Regulation

    Many boats, specifically sailboats, come equipped or have have used the 5" case Motorola/Prestolite/Leece-Neville style alternator over the years of production. Many Ericson's used the popular M-25's and these engines use this same case style. This case style alternator today is built by...

    It all started out with a low alternator output..................

    Hi folks I'm really tired of working on my boat and just wanna sail, or win the Powerball and buy a new one. But alas, I can't buy a new Ericson anyway. Here goes: I wasn't getting a good charge on my batteries from the alternator. I check it and find only about 12.1 volts coming out. I take...

    Installing an alternator bracket kit

    Last week I took my alternator in to the alternator shop as it was only putting out about 12.1 volts. It needed a new regulator. It was serviced and some kind of waterproofing put inside. 80 bucks. I was unable to tighted down the alternator bracket tensioning bolt. I discovered that it...

    Alternator Belt on Universal M12

    I have a 1986 E28 with the Universal M12 Diesel. The alternator belt is a little loose, yet the bracket that holds the alternator is maxed out. The belt is the correct size, and the previous owner says it was always like this. He was concerned, but never had a problem. Is there any reason...

    Hot Alternator

    Hello there, Just installed a new Balmar 100 amp alternator. Seems to be getting really hot and battery bank # 2 doesn't seem to be holding a charge very well. Will this alternator keep trying to charge batteries that wont hold much charge and get really hot or does it charge the...

    alternator replacement E34

    Ah, the joy of upgrading your batteries from wet to AGM, and expanding the size of your housebank (to 400 ah)....The orginal alternator for the universal 25 on my Ericson 34 is no longer helpful. I'm looking for a good alternator replacement (size around 100 Amps) with smart regulator. Anyone...

    Charging Voltage from alternator

    We recently replaced our older standard wet cell batteries with 430 ah of gel batteries. I have historically been very bad at maintaining standard batteries, so I look forward to getting a long life out of these with no worries. However I do unfortunately have one worry remaining. At the...

    E381 Alternator

    The alternator on my '82 381 (Universal 5432) recently crapped out 20 miles offshore and I dropped in my spare in 4 mins flat- no problem (glad I had one). So I took the bad one (it has no markings, manuf info, serial # or markings of any kind on it) to West Marine and they said that with no...

    New alternator difficulty

    I just bought a new alternator to replace the stock(?) 55 amp. The old one was wired for an Alpha external regulator. The new Leece-Neville 51 amp alternator is nearly identical - although it has an on-purpose tap for the tachometer. I wired it for the Alpha regulator and when I turn on the key...

    I am in the process of installing a Balmar alternator on my 1985 Universal M25 engine. In the course of researching the mounting (on the Catalina site) I came across dire warnings about how the pre-1988 method of mounting to the bracket, which is attached to the aluminum gear case, will...

    Alternator RX

    A few weeks ago I finally got around to installing a Link 20 battery monitor that I had purchased a few years ago. When I fired it up, I was shocked to see that the charge voltage at the battery was down to 13.2 volts (basically useless). I have now implemented wiring change "A" recommended by...
