Split lock washers
In all my years of dc electrical work we had one common absolute...no lock washers. Now as I help my neighbors with their cart problems I find split steel lock washers being installed by the local golf cart dealers when installing new batteries and cables. What I find is after repeated heating and cooling these washers loose tension and we end up with melted battery posts, loose connections causing resistance and loss of speed and so on....am I wrong?😎

I have serrated flange nuts on mine now, but notice they also tend to damage the cable terminals. But I like the secure connection regardless. A smooth flange nut is possibly a better way to secure cable terminals without damage. These can even be used with solid copper flat washers for a heat flexible connection. I would regularly tighten all connections made with a smooth flange nut. |

Re: Split lock washers
These should be the ideal battery terminal nuts.
No lock washer needed, secure from loosening, stainless steel, inexpensive. http://www.boltdepot.com/Product-Det...x?product=7404 |

Re: Split lock washers
Maybe I am missing something. The battery posts shouldnt be getting hot enough to alter the physical properties of steel. If everything is sized properly and free of corrosion, the wires and post should get warm at best.

Re: Split lock washers
It has to do with vibrations loosening the nut and causing connection issues.
Opps, I see it references the heating and cooling of the terminal. |

Re: Split lock washers
I don't think the battery connection qualifies as "high-vibration", but I think the main issue with "locking" anything is specific to the "stud" battery posts.
Anything that causes torque on the stud by itself is a bad thing for the studs embedded in lead, the "nyloc" would be the worst followed by the split lock washers. Those devices can eventually cause the stud to get loose, of course that is assuming You are constantly removing the battery cables.... I think for practical purposes anything or nothing at all between the nut and the lug will perform the same. As mentioned, checking the torque on those nuts is a periodically good preventive maintenance measure. |

Re: Split lock washers
I have had electric carts for around 15 years. Many of the paths are quite bumpy with the tree roots pushing the asphalt up. I have only ever used plain stainless nuts and have never had one come loose.
