FWIW..Take DRTOM'S advice and install a set of GOOD cable ends..

 

Technically, that's DocOlds advice from long ago . . .

 

technically, i do not ever recommend cutting off a perfectly good,"end"
i modify it,maintaining the super crimp and add a good conn,never incorporating a new weak point.
end result is maintenance free solid brass connector, without the "weak link" created by cutting the cable.

NEVER CLAMP STRANDED BATT WIRES
