Had To Do Some Paddling Today on the Lake

[Been There]

You know something will probably happen when the day is sunny, warm, and no wind to blow you off the lake. That was the case today, only there is a minor flaw just about to happen.
I launched the boat, trolling across the lake and about in the middle (1/4 mile from shore) the trolling motor quit. BAM!. no 12 volts. Checked the circuit breaker and it was good.. However, the plug from the trolling motor cable was HOT. In fact it was melting the plastic connectors. Dead in the water as they say... so it becomes paddling time, and back to the dock and ramp I paddle for what seems half hour. Which means boat back on trailer and head home to find the melting cable plugs.

It appears the new just purchase "Anderson SB50 Quick Connect 6 guage battery plug connector was a waste of money.
I knew I had a spare Twist Lock setup, so I wired that all us and run the trolling motor at 5 speeds for half hour and no hot wiring to be found. I would guess the Anderson SB50 plugs was faulty.
Tomorrow, back on the lake. With cross fingers.

Looking at the spedcs, it shows should be able to handle 50 amps continuous, so thinking there might be something else in play

My setup is as follows: The battery is a Deka 810-amp marine Deep Cycle (Model #DC31DT) 12 volts with a Minn Kota Endura 55 thrust only connect to the battery. All other 12 volts items.. Lowrance Mark 5K Pro, and others are only a separate 12 volt battery.

This is my first to used the Anderson SB50 type connectors. So, I'm just going back to the old style Twist-Lok type, which I'm familiar with on the last thirty years.

NOTE: When I installed the SB50 the two connectors didn't seem to mate to what I would consider a good match. There were some "loose" no tightness there.

your 55# minn kota draws 60 amps per the minn kota web page

the SB50 is a 50 amp maximum plug.... and most of the ones you find on the internet are chinesium knock-offs. no problem with a SB75 or SB100, however the SB50 is undersized.
