Dead Unit... HELP!

[rocketman]

My D10A is dark. Power at the connector, but unit will not come alive.  Is there a fuse that can be checked, or, perhaps a way of diagnosing the problem?  Unit has performed flawlessly until now.

TIA,
Jeff

There are no fuses or anything like that to check. The first thing to do is to pull ALL power from it, and this means the internal battery as well, if you have one. Just pull the rear door and then unplug the connector that is right there. You also need to pull keep-alive if you have it, but that happened when you pulled the D25 connector.

Once you have removed all power, if adding power back doesn't turn it on and you are sure that it has power at the connector, then we'll need to look at it here.

Did you check between the power and ground pins, or just from the power pin to aircraft ground? It is possible the ground is loose, and you aren't really getting power to the connector.
