Bad Battery Connector?
If your motor keeps losing power or you can no longer attach your battery to the power cable, you might have a bad battery connector. I have found that these connectors are readily available online at Grainger
This connector needs to be replaced.
They are called: Anderson Power Connectors. The Grainger number is: Item # 3BY20. They are approx $6.50 each and the content of the package includes two replacement solder type connectors, the shell and an Assembly Sheet.

With these parts, you can repair your broken Battery Power Connector and get back on the road without too much hassle
