Xantrex Battery Monitor

Guest · Post by **Guest** » Tue Jun 20, 2006 1:24 pm

Has anyone had problems with their Xantrex Link 20? I have hull #240 built in 2005.

Over time, the monitor shows that Battery 1 is discharging - despite being plugged into shore power and charging - and eventually the monitor lights go to a single red light (over a few weeks.)

McMichael Yacht Yard has worked on the monitor a lot - resetting/reprogramming - even replaced the monitor and we have the same result.

Has anyone had a problem with their monitor?

I have seen a similar problem. I reset my monitor and was on shore power at Block Island and the battery was showing as not receiving as many amps in as out.

I have the same situation as described by Joel on #288.

We also have the same problem on hull 264. Any advise welcome. We reset the Xantrax and amended some of the parameters but after a short time it goes to the red light.

I'll assume that although the Link shows the battery as dying, it isn't actually, correct? Put a meter on the battery posts and see if it is healthy. If it is, then the Link is seeing only the discharge from the system, and not seeing the input from the charger. Probably will be traced to miswiring. I'll lay odds that the negative lead from the charger is hard on the battery, and not on the shunt. So the shunt sees all of the discharge loads but doesn't see the charging input. Track the negative from the charger and see to where it is hooked up.
On many of the boats, they (Pearson) located the shunt up in the nav panel area, not down by the batteries. Then when they lead the charging leads they didn't route the negative up by the shunt, so the Link won't see it. This has supposedly been corrected on newer hulls.

We have this problem on hull 263 as well.

I have #288 - same issue. McMichael's sent me a Link 2000 unit to replace the Link 20 with. Has anyone else tried this fix?

You can use a Link 20, a 2000, or a pair of Link 10's. If the shunts are miswired it won't matter what model you use - it will not work properly.

I have #334 and it's still a problem. The batteries are charging fine but Bank 2 shows being fully discharged. Bank 1 reads correctly. I have submitted it for warranty work, and I will REMIND TPI that this is still a common problem and a permanent fix needs to be applied.
