Link 2000 OL fault

[Seaman gagging]

Link 2000 connected through a freedom charger. Now it shows an OL fault when amps are selected. Amp hours counts up quickly. Batteries still charge, inventor works. Powered the link off and still the OL. Should I do a complete reset? All lead acid batteries. House and starter bank selected same fault. Thanks in advance for any advice

Yes, do a complete reset. It's in the manual, also available online if you don't have the original.

DISCONTINUED XANTREX PRODUCTS LINK

Discontinued Power Inverter/Chargers

and for Link products:

Discontinued Power Accessories

You may also have to disconnect and reconnect the phone cable, but do it in the right order.

Thanks Stu, I really appreciate all your texts. I'm a fellow Catalina owner. I have learned volumes from you.

Always glad to help. What boat do you have?

My "Greatest Hits" are here: "101" Series - Quick Links to "Popular" Topics includes "Electrical 101"

Only reason I mention it is I just came across a post from someone on another forum who asked Maine Sail to write a book!!! As if his website and contributions on the internet weren't enough. I thought it quite cheeky!

Instead of doing my own blog, I chose to do all my stuff on our C34IA website, so when I'm gone it'll still be there.

No hurry though, I got miles to go...

Mine does that about once a year. I go to the fuses and disconnect them both, then reconnect and it starts over. You don't have to re-enter all your settings.

Check the connections at the back of the Link 2000 and the shunt. Especially check the black wire (ground) since it is used as a reference for all measurements.

It is supposed to be attached to the shunt on the side opposite the battery negative. Make sure it is nice and clean too.

Good luck.

Stu and friends, I have powered down the unit, no help. I did a factory reset,no help. I loosened,cleaned and tightened all connections. Nothing. Still OL message. Amp hours function shows amps counting up continuously. Voltage function works.
What am I missing? The unit is sealed, so I can not check wires going into unit. Any tests I can perform on the shunt grounds to see if I have correct amperage going to them? Any suggestions would be appreciated .

The most helpful thing would be for you to take some pictures of the shunt and the connections at the back of the Link 2000.

Still looking for a solution! Amp hours continuous count up on both battery settings.amp reads OL. Volts read fine.pictures of set upe
Any suggestions appreciated.

Sorry you're having problems with your Link 2000 but it's entirely possible that your unit is failing. That happened to mine after about 15 years of hard use - gradually features began to quit working, the display would be wrong but I could still activate the invert function and the charger still worked. I'm sure you know that the unit has been discontinued for years and that Xantrax no longer provides support for it. We milked ours for years with it barely functioning and finally bit the bullet and bought a Victron.

I wish I had more positive ideas and perhaps someone else can offer a solution, however, there are lots of posts here with others who have had these units fail.

Good luck, fair winds and calm seas.

Bump.

My only idea is the connections, but you have already checked these.

Anybody?

Before you spend any money on new equipment I would replace every crimp connection on that shunt including the battery cables.

A shunt reads milli volts and all of those connections could easily be your problem.

[Seaman gagging]

Thanks for the responses. Is there a way to test each connection? What volts should shunt read on multi meter? I have already taken each connection off and cleaned best I could.
As discussed system was working fine for years. No changes were made to the system.
What connections would you start with?
Thanks again

Opie1 suggested ALL of the connectors. I agree. Those very small wires are the culprits, probably, but who knows, one of the big ones could be it, too.

One VERY IMPORTANT idea a friend shared with me a long time ago:

ONLY do ONE thing at a time, and then check everything. ONLY AFTER you've fixed one, then move to the next.

It's the ONLY way you'll know where the failure was.

And each wire has TWO ends, right?

Inch-by-inch, row-by-row...

Good luck.
