I have a 1999 Hunter 410 and it has a Link 10 which has been working really good until about a day ago. It has now begun showing a constant draw on the amp selection of around -5 amps constantly when there is absolutely nothing turned on. The ah selection reflects the calculated total as the day goes on. I'm puzzled as to where to go. I have 3 grp 27 batteries. Has 1 of them gone bad? Can anyone point me in the right direction? Thanks.

Yes - it appears that something is drawing current. To test that you can disconnect one of the batteries and see if the current draw changes. If not switch to the other battery. You can also disconnect all batteries to see if the current draw is at zero. Also try switching off all the instruments at the panel.

Insert a DVM in series set to the 10A scale between Batt Neg and the shunt. If you have 5A on the DVM the Link s accurate and you need to now track the problem. If you don't have 5A on the DVM then the Link has gone kooky...
