tried to start the tractor - click! @%!*#@ broken ear on the terminal. None on the place so off to the local discount emporium, found'em & grab'em & hand almost hit the ceiling. Expecting lead but these are aluminum. Anybody else seen that? Are they any good? At $2/pair figured they'd get me started anyhow. They work good. Loose in a bin & no country of manufacture on them but seem to be East European or middle eastern. Think "ARE" is stamped on'em.

I suppose that you could tin them of sorts by coating them with lead. One thing remember from years ago when taking exam for FCC license, is that they recognize in order of metal conductivety, best to worst (excluding gold for some reason)...SCAN (silver, copper, aluminum, nickle). Perhaps the goal is to get you better radio reception while operating your tractor. You have to admit that when out on a tractor all day and maybe all night, a radio comes in handy unless you're using a noisy Hiniker cab. Comfort cabs are much better for radio speaker quality.
Good luck.

definitely Aluminum. One was painted red (for positive) & other painted black (neg) altho the hole sizes are identical. Some paint'd run down the inside of the hole so I filed it off with an old chainsaw file. Aluminum. Showed'em to my buddy, first time he'd seen any & he works on tractors all the time. The bolt & nut with'em is steel. The hole sizes are NOT tapered like better quality terminals are, to fit the tapered top posts.
I wouldnt use them.No taper means they will contact the post in a small area.I use solder on brass terminals and you can buy copper terminals.The brass terminals that look like hose clamps are trash and will corrode away in a short time.Terminals that clamp on the cable with bolts give you another place for a loose connection.

Gold is not as good a conductor as is silver. But gold is immune to chemical attack from almost everything, mercury and Aqua regia being about the full list. Since Aqua regia occurs only in the laboratory, not in nature, gold plating is good protection from corrosion.

Aluminum is more anodic than lead. Lead will be the cathode and Aluminum will be the anode. So in the presence of a medium such as water the electrons will flow towards the aluminum. Spray the connection with a Loctite battery protective grease. The other issue is the fatigue resistance of the Aluminum cable in vibrating machinery. Minimize any cable vibration with tie-downs.
Bus Driver,
I found out about Gold and Mercury the hard way. I got some Mercury on my ring and the more I tried to get it off the worst it got until the whole ring was silver. I had to take the ring to the jeweler to get the Mercury removed. I know that you shouldn't handle Mercury but that was back then when it didn't hurt you.

He's right. I've seen battery cables that have aluminum connections. Don't like them either.

What's a cathode and anode? I thought diodes had them. Is one electron rich and the other electron poor? Or does it have to do with the number of electrons in the outer ring of the atom? Sounds like chem 101 on yesterday's tractors.
The bottom line is that electricity is smoke that moves through the wires and if any electronic devise goes up in smoke, it stops working. So if your cables start to get hot, look for the smoke to follow

If Bob hasn't seen it then it doesn't exist and you are a liar. Guess we forgot about that, thanks for the reminder, Bob.
