    Posted: 05 Nov 2024 at 7:55pm
So I have a D19 that I’ve switched to negative ground and it charges perfectly but for some reason I get an excessive amount of corrosion on the terminals,battery tray and below the tray on the side panels and anywhere there’s a bare spot where the paint is chipped,even the bolt heads. Any idea. Thanks in advance

Probably not much. Clean everything up well. Use a weak baking soda solution to clean all the acid up and do that once or twice a year. Apparently negative ground systems are worse than positive ground for this problem. Also make sure you are not in an overcharge situation as that will make it worse - leakage at battery. Make sure the grounds are good and clean at both ends of the cables.

I realize battery polarity discussions can get worse than oil threads, however I had always read that the reason for positive ground polarity for most vehicles before the 60's was reduced body corrosion.  Not sure what the compelling reasons were for switching to negative polarity around the early 60's.

X2, I heard that same theory. Right or wrong though, negative ground definitely won over as the standard of the industry.

That’s interesting to know, I’m really thinking of switching it back to a generator and positive ground.

Check the charging system output, my guess is it's over charging and boiling the battery.

Key Points
  • Battery terminal corrosion is a common problem that can disrupt the electrical current in a vehicle's starting system.
  • Corrosion on car battery terminals can be caused by overfilling the battery, leaking battery fluid, overcharging, chemical reactions with copper clamps and age.
  • Cleaning battery terminal corrosion involves disconnecting the battery cables and using a stainless-steel wire brush with a mixture of baking soda and water.
  • Preventive measures to avoid battery terminal corrosion include using anti-corrosive sprays, coating with petroleum jelly or dielectric grease, avoiding overcharging or undercharging and performing routine checks.

Check your charge rate for being HIGH... make sure TERMINALS are LEAD and not COPPER..

Anything that you can do to preserve this irreplaceable jewel is well worth the effort.

As others have mentioned, it is likely over-charging. If the tractor is used for field work where it makes long runs between startups, 14.0 Volts is great gobs of plenty, 13.8 Volts is actually sufficient to keep the batteries up.

Also consider switching to a sealed AGM type of battery. Yes, they are expensive. So is rotting away your precious Allis.

The positive-ground generator was adequate for many years so there is no reason it cannot still git'er done.

most cameras take photos that are 4000 x 3000 pixels and 5 Mb in size.. Email to yourself and shring or put on the computer and open in PAINT and resize to about 800 x 600 pixels and 100 kb in size  and then the site will accept it.

Facebook and some others will "resize to fit" for you... this site will not do that.
