Without nuts and bolts, 4.75 oz and 6.75 with (positive), the negative about .35 oz more.

Compare crimping, NAPA crimped with special tool and mil spec. Assurance of quality from the counter salesman was "That ain't going nowhere". They will be installed, but I'm not terribly happy with them. Also received the correct battery terminals.

The first one covers the 6TN battery also, replaced in Dec 1987 with 6TL. The truck came from factory with 6TN types. All good info, Thanks.

Re: Clamps That must definetely have been the lowest bidder making those. :-) The only reason a battery terminal gets hot is when the connection is bad.

I shouldn't, but how is a "modern" relay better than an old military hermetically sealed one made for the full mil spec temp range, g-exposure etc or how is weatherpack connectors superior to the silver plated rubber protected Packard ones? Like I said, I shouldn't, but I'm just the opposite, I...

Isn't it nice to have this kind of info available, thanks David! Note that the nuts and bolts are to be zinc chromate or lead covered, not cad plated, all to reduce corrosion. What's the mil spec on the battery if I may ask, MS35000-3, perhaps the terminal alloy is specified? :D

Cast copper is compatible with the copper wire in the cable, but not the normal lead posts on the battery. A difference in temp coefficient can possibly create problems. My local NAPA will crimp my cable lugs to spec, at least they say so, haven't used that service yet.

Re: Clamps May have something to do with material compatibility for minimizing corrosive action, battery post to clamp to tin-plated lug.... Component parts appear to have been selected for a current draw of 250 to 300 amps max, that is the rating for the cable, slave connector and possibly...

Clamping a wire is nowhere near to compare to a properly done crimp or solder connection. Strands will separate and corrode. Perhaps it's a good thing that they are not available. :-)

This should be of general interest, the matching of battery terminals to cable lug to cable. Note how the 1/0 cable is connected to the battery clamp, it's tin plated and the opening in the lug is 3/8, like the bolt in the clamp and the outside dia matches the outside of the barrel of the...
