Good catch and troubleshooting tip. A loose connection is a bad connection. ;)
normal you see 2 colors gold and silver.i saw only one color (gold).
thats when i notest some is missing.
May be a good time to switch to XT60 or even XT30 connectors? I did that for all my RC stuff over 5 years ago and never looked back. Deans can be a pita to connect and over time begin to disconnect too easily. In parallel harnesses or parallel charging boards, they are a giant short circuit risk. Their only redeeming quality is that they provide high amp capacity in a small for factor, but most of us dont need 100A for our robots.
