Re: alternator smart regulators

Very wise. Other option is to have a backup new regulator. So many sail with backup alternators, why not a backup regulator, too?

I used to carry an old prestolite regulator for a backup. It originally came hooked up to my old Balmar.
An interesting exercise; Balmar vs Next Step; I had the Balmar version 3 and the Next Step on my HansChristian38. 100 amp alternator/single belt. I tried both, the Next Step was head and shoulders above the Balmar as far as the first 15 minutes of output... by something like 15 amps! I had to take the Next Step off as I just couldnt keep belts on the engine with it. I imagine Balmar has improve that a couple versions later...
As far as backup in the field, just hook a wire from the battery to the field and keep watching the amps out put/temperature...

So what does happen when they fail? Do they run wide open? I've kicked the can down the road on that one and not sure what I'd do besides slip a little hitachi back in there. Kind of spendy for a spare ARS-5, and I could make do with 20-30 amps. Mine is a hehr power line tuned down to 70 A. Great technology.

Depends on how they fail, but most common is no output at all. Although, I have seen runaway voltage too, but less common I think.

Not sure I'm clear on how to build a manual one without frying alt.


What does one see out there in the marketplace for an inexpensive spare? Cheechako is the prestolite something on the market? I've just never seen an external regulator out there at napa etc

Re: alternator smart regulators

I saw an install on a gulf 41 that had the spare mounted right next to the primary. In case of a failure you could swap the wires. I thought it was a pretty good idea as a spare storage thing.

I still might be willing to carry a identical spare depending on where I was going and for how long. With an older or smaller spare, it's just a stop gap fix, and you could still be in the middle of nowhere needing a part that needs to ship massive distances and hoping everything goes right. If I could afford it, I'd get an identical one just for the halibut.

A $10.00 Ford external regulator off eBay makes a great get you home spare.... They use the same plug format as Balmar, Xantrex and the old Heart Interface regulators....

Re: alternator smart regulators

And THEN maybe the old stock one that came on the boat, just in case.

2 is 1 and 1 is none

Cool. I like the sound of $10. I wonder if I have one if those in the parts room..... ?

Thanks again for bringing it up Belize, nice to have a solution.

Several companies make external single stage regs that are cheaper than three stage.

Like http://www.defender.com/product.jsp?...289953&id=6468

And http://www.hamiltonferris.com/produc..._Regulators/11

Plus, alts built on the Delco cs130d (like Balmar series 6) have a built in internal reg on standby.

My new (2010) Balamar alternator has an internal regulator and connections for an external regulator. They recommend a two way switch to power the internal or the external regulator.

This is a good backup to get you home but surprisingly it regulates to only 13.8 volts.

Yes, a fine design idea. Internal regulators are typically less intelligent than externals so the 13.8 does not surprise me...better than some automotive regulators that have even lower set points.

You're welcome. Always important to have a plan B...and a plan C, D, E....

My original install, by builder, was a single Next Step controlling two alternators (twin engine) so it was a single point of failure. My new install will be a seperate Next Step for each alternator so I've got built in redundancy....AND I plan to carry an external regulator too.
