While I don?t disagree with replacing the cable, a quality splice kit will actually cost as much, or more, than a new cable, so there goes that theory....
.....everybody sure likes to ?pile on? in these forums.... risk an airplane with a spliced cable, really guys.... hope you don?t have a simple alternator failure or youre doomed!
The OP asked if there was a suitable way to splice the cable. There is. Enough of that.
That said, if it was me, I would replace the cable, but that?s not what the OP asked.....
