alternator

I found kits for Universal engine but none for the 5424 or M30 (which are practically identical). Existing Kits are: M25, M25XP, M25XPB M35, M35B M40B M50, M50A, M50B, 5444 5432 I would appreciate hearing from anyone who has installed a serpentine belt for this particular engine model or...

We have an ericson 38, 1989.We are currently in the Bahamas cruising and our alternator has died. It is a prestolite with 4 wires. 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...

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...

I took the original starter motor from my M25 to Luis, who came recommended by a gold-plater yacht yard in Marina del Rey. JB Auto 10967 Venice Blvd LA 90034 310 839 8685 He took it apart, greased it, and ground the bendix fair while I watched. Cash deal. Reinstalled, the motor cranked...

Imade the decision to take out my old alternator on my 1992 Yanmar diesel.Decided to use an external smart regulator from Ample Power co along with A new high amperage Alternator.Upon instaliation I made the stupid mistake of leaving a live wire,it shorted through the new alternator...

Just installed a Victron BMV600 battery monitor and everything is being read except the alternator charge. Per another excellent How To by Maine Sail he describes the install and also touch’s on my dilemma- “Keep in mind that many marine alternators are case grounded and thus the system...

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...

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...

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.

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...

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...

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...

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...

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...

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...

Hi Guys I am installing the alternator bracket upgrade on my 82 M25 Universal. I searched the previous posts and see others have completed the upgrade in a short amount of time. I have the old bracket off but cant get the studs out of the coolant case attached to the engine block. Any...

As noted in other threads, I recently upgraded my M25 to a 90 amp marine alternator made by Prestolite, Leece-Neville division. Prestolite is an old, respected name in automotive applications and their Leece-Neville division makes alternators for emergency vehicles, farm & construction equipment...

Well here is the deal.....the Beta Factory recommends leaving the std 40A alternator to charge the Start System and install the Balmar 712-80 as a House System charger (space constraints) :boohoo: Would appreciate FEEDBACK (Pics) on how to install the second alternator on the Beta 902 (3)...

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...

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...

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...

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...
