big problem

Good morning all,
Have a super big problem with the K3 :-) Every time I move the K3 the power plug falls out. Changed the connectors and still comes out with the slightest movement of the rig.
Any suggestions on keeping it snug. Tried tweaking the contacts with no luck.

Not really a problem just a little annoying.

Re: big problem

Do you use Anderson PowerPoles for anything else in the Shack?
If so, try one to see if it's the lead end or the APPs mounted on the
board.

Did you solder the APP to the lead?
Double check the contacts are pushed firmly home.
Any chance you got too much solder on the contacts?

In my experience (all my 12v gear is APP), it takes quite a lot of
'pull' to separate them when they are made correctly.

Morning, Don.....
I had the same problem.
I had not installed the clips properly in the connector. By this, I mean
that I had not pushed the metal clips far enuff forward for them to "snap"
into a locked position. Because of this, they would cause the connector to
disengage with the slightest movement of the radio.

Look at the assy manual very carefully with the connector in hand.
I believe you'll see this is your problem.

Good luck.

Re: big problem

What Dick mentioned is entirely true in my experience, but I might add
that the condition should be corrected promptly. The fact that the
connector is loose also says that there is a marginal electrical contact
that is prone to arcing and heating, and in the extreme could cause a
fire to develop. For your own safety as well as the health of your K3,
correct it promptly.

Same here - just by brushing up against the cable I often lose
connection. Been a problem recently as I was interconnecting the K3
with the rest of the station. I think I will make a new cable
assembly and see if that helps.

PowerPoles are great for quick connect/disconnect, but in a radio
that just sits on the table month after month a more secure connector
might be a better choice.
