Anderson Powerpole voltage loss

Dale
A fellow ham here in VK recently complained of a significant voltage
drop (2V) through Anderson Powerpole connectors. Has anyone else
experienced this on the powerpole connectors fitted to the K3 or
elsewhere for that matter?

Hi Dale,

When these connectors are properly assembled, crimped and/or soldered,  
they should drop a very small fraction of a volt even with a 20-amp  
load. The data sheet can be found on-line; check the resistance  
specification.

Dale,

Also make sure the pins are fully inserted into the plastic housing so that
you hear it snap in.

The gentleman also discovered the contacts were "dirty", after cleaning they
showed normal and expected voltage...:-)

aaah..housekeeping chores are a necessity of life....but why are we so
prodded by our XYL's...?  (Grin)

I have never found dirty APPs - the whole idea is that they wipe each other as joined and unjoined.
This suggests a badly fitting contact in the housing.

"Improper mating is usually caused by one of the contacts not being fully
inserted in the housing. The contact may be shoved in as far as it will go,
but if it was crimped poorly or soldered with too much solder on the outside
of the terminal, the bad crimp or solder jams against the side of the
housing before the contact is fully in place."



After experiencing poorly seated Power Pole contact issues a number of years
ago, I now keep a small flat blade jeweler's screwdriver in my Power Pole
contact parts drawer.  After I push the contact/wire assembly all the way
into the housing, I insert the flat blade of the screwdriver into the back
housing opening.  I align the blade on the edge of the round crimp portion
of the metal connector and give it a firm push forward.  I was amazed at how
many times I got a nice crisp "click" from a connector that I was convinces
had already been properly seated.  Try it.

Re: Anderson Powerpole voltage loss

In reply to this post by Dale
G'day all,

thanks for the many infromative replies to my question about Anderson
Powerpoles. I have been using Anderson Powerpoles for some years now
with great success. I use the Powerworx crimping tool and have never
had a failure. The original question was raised by me in response to a
comment made by a local VK ham who was having voltage drop problems
through his powerpole connectors. It appears that he was not using the
correct crimping tool and also that the connecting blades were dirty.
Looking forward to my KPA-500 kit.
