Battery connection

Every year, mid season, my boat refuses to restart after picking up a skier. The issue is always a bad electrical connection at one of battery terminals. Here is what the connectors looks like.



One source of the problem is the post connection. No matter how much I clean and tighten them during spring reinstalation, one of them loosens up. There is only so much they can be tightened. The other problem is where the cable is clamped into the connector. Even after cleaning the wires and retightening the cable clamp bolts, the connection ultimately goes bad.

I am considering other types of connectors and whethere soldering would help. Any suggestions?

Those things are the worst kind of crap. Toss them in the tide and do it right!

In regards to the above mentioned Marine battery with Marine type connections: The only limitation there is that those batteries won't necessarily fit in the short Ski Nautique Battery boxes.

I bought the solder type from my local NAPA store. The terminals are pre-filled with solder. All you do is heat them up and shove the wire in. They work great.

Quite possibly the wire is corroded even under the insulation.

The entire cables may have to be replaced.

True enough but I found out that battery box is much better suited to holding 12 beers and 10 lbs of ice.
