[RE-wrenches] Outback question

[Jay]

I’ve got a interesting problem I’ve not seen before. 

Mate 3
Hub
Radian
Fm-80

It’s been installed for 5 + years. 

Recently the caretaker noticed every other day it wasn’t charging. This is confirmed on the CC and logging. 
It was in float all day. 

We disconnected it from the hub and it’s charging normally. 

I’m not aware of any mate 3 settings that would make this happen. 

Comments?

Thx

Jay
