Check polarity on main Anderson leads.

Was this from the kit of parts?
Uh oh… Such a simple problem can lead to devastating results…
Yes.
We had it wired into our power distribution board, but found out and nothing got damaged.

Is there a way to make sure this warning gets out to all the teams?
Notify FIRST asap. There is a team blast coming out in a couple of days.
How does one “notify FIRST”.
Is there a process in place for this?
Email [email protected] per the contact page on the FIRST website.
FIRST has been notified and are aware of this discovery…
All done.
We had this all wired up to our Power Distribution Board. Once we plugged this in we heard lots of clicking and quickly unplugged the battery. Luckily our PDB, two Talons, and my RC equipment went undamaged.
Since we only had minimal electronics installed we were quickly able to diagnose the issue and continue testing our drivetrain. :yikes:
Magic Smoke averted…
Wow I got to check ours now then haha
Everyone should check their KoP components. This should be relatively easy to fix when discovered. Switching the contacts in this connector is pretty simple. I’ll make pictures about it upon request. We put one on the new battery and I’m chagrined to realize I didn’t check it - - - - yet. The battery beak worked though, so maybe we skated on this one.
From what I remember, the KOP battery cables have an extra crimp in the plastic that makes it more difficult to remove the contacts. I’m afraid that FIRST night have to send out replacements.
First KOP engineers are being notified now.
Are we going to get replacements of these, or is there a way to swap out and modify the plugs?
The cables can be reversed pretty easily.
The connector attached to the wire slides over a flat spring in the housing to latch securely. You just need to depress the spring from the front of the housing and lightly pull out the cable. Reinsert just by pushing it back into the housing.
Avoid scratching the top of the connector, so the contact surface isn’t degraded any.
You can see the flat springs in the cutaway below and the little lip at the tip of the connector that fits over the end of the flat spring to hold it securely in place.
Alright, sweet. Actually, we didnt need to though- the plugs we got were of the proper polarity.
Just to check, have a lot of teams found these or is this a rare event at this point? None of ours were incorrect.
Ours were correct.
Ours were correct as well.
A good lesson learned is always check these kinds a things, even when they come from a reputable vendor.
