Xantrex Link 2000 Troubleshooting

[yachtingtypes]

This last weekend an E13 error came up on my Xantrex Link 2000.

I looked in the manual and it said “Battery #2 voltage sense leads open”. So I checked the violet wire connections to the start battery (my #2) and replaced the 2A fuse. It was all fine until I turned a small load on and then the E13 error came up again.

I then disconnected the blue wire fuse (battery #1 or house batteries) and as expected E12 came up. Even when I reconnected the blue wire fuse the E12 error continued. It wasn’t until I pulled the fuse on the start battery that E12 was replaced by E13.

So I have replaced both fuses (although the old ones looked OK and the Link 2000 was still showing the voltage from battery #1 and #2). I still have an E12 or E13 error depending on which fuse I last disconnected. I have a Heart Freedom inverter/charger connected to the batteries and the Link 2000 controlling it.

Any ideas as to what to look at next?

What kind of fuse holder do you have? I have seen this error on my previous boat, which had a L2KR, and it was due to a bad connection inside the fuse holder. It is sporadic, and if you don't have a load on the batteries, the bad contact is not a problem, but a slight voltage drop at the battery combined with the bad connection in the fuse holder can be enough to cause the L2KR to see a low battery voltage.

I have seen this sort of problem with 3 fuse holders, in 3 different applications, and all of them the ones that use the glass tubular fuses. I eventually replaced them with automative blade fuse holders, and all was well. Now I NEVER use the glass fuse holders for anything.

Thanks for the response. I also received an email from Xantrex customer service.

They suggested that I try hard reset of the Link 2000 by disconnecting all power and letting it sit for half an hour. I will give this a try before pulling the wiring apart.

The hard reset worked. No blinking errors!
