I'd have to agree with jinman. Dielectric paste is a decent insulator, and as he said.. once the post is tightened down.. most of the paste leaves the joint for a metal to metal contact. Won't wurt as a gas / liquid barrier though.. works well. Silicone DE paste can be picked up in tubes where you find plug wires.. good lube.. decent to keep 'lazy' KV where it should be inthe case of wet wires.. etc..

I've always wondered about this issue. I know that dielectric grease is electrical insulating grease. Applying it to critical electrical connectors before connecting them seems to be a
standard proceedure.

Steve, my best guess is that the connector pin and socket has metal-to-metal contact when the connection is made and the dielectric grease prevents moisture and oxidation around the physical contact point. Also any heat due to contact resistance is better transferred if the grease is there.
It's possible I misunderstood jimmysisson's comment. He may have meant that putting vaseline on the terminals would ensure all the voids were filled with grease and prevent the buildup of oxidation. That would work if you had good terminals and connectors that could be tightened enough to make good contact instead of worn ones which might not be ideal. If I misrepresented him, I apologize. /forums/images/graemlins/blush.gif

The best stuff to use for battery terminals that I've seen is Fluid Film. It's non-conductive so make your connections first, then spray some on and you're done for like a year. I've never had a problem since I started using it. Here's a link to their site.

</font><font color="blue" class="small">( In order for grease or Vaseline to protect my tractor from acid damage and corrosion I would have had to coat the battery terminals, battery shelf, front latch, radiator, grill, hydraulic cooler & hoses, motor, and a bunch more parts. )</font>
Steve, my 40D was about a little over a year old when the battery started delivering acid all over. I told the dealer I wanted a new radiator, oil cooler, battery tray/support and anything else that was corroded. Fortuneately, the surface of the engine did not seem to be effected. They took care of it and replaced everything I asked for. Hopefully yours did the same? /forums/images/graemlins/confused.gif
When I received the tractor back, I then lowered the level of the fluid in the battery to just above the plates, and all seems to be well since.

djradz,
Since I'm extremely dusty here, I can't use grease. If I greased my battery posts, they would be 6" dust balls in no time flat.
Instead, I taped a sheet of plastic film over the top of my battery to contain the acid spatter. It came off a while back when I pressure washed under the hood. Last time I checked, there was no acid on the battery or posts. Maybe my acid level dropped like yours.
I don't like that battery and I hope it croaks, but some day I'll check the electrolyte level out of curiosity.

- 1993 NH 2120 (the best), 1974 MF 135 (sold, but solid), 1947 Farmall A (bought, sold, bought back, sold again), 1956 MH50 lbt (sold, in 1980, darn it)
Jinman I think I've been using the word wrong for years. It's not my field, just a word I heard a couple decades ago and took up wrong. Still, I've always gotten a good connection at a battery that I smeared with Vaseline, and I do like that it's clear so you can see the parts. Used to be you could buy little felt washers that fit on the posts under the terminals that you could saturate with grease or some such and that would keep down the corrosion. I don't know if they're still available. My 2120 has the front-and-low battery but it doesn't seem to bother the way this thread talks about. Thanks for clearing up the definition. Jim

They're still available, red and green, that fit on the posts, although you don't put grease on them. Converting to a dry cell battery solved all these problems for me. /forums/images/graemlins/smile.gif

Mike, I've got to ask: When you say "dry cell", do you mean "gel cell", "AGM", or true dry cell as in NiCd or NiMH batteries? I assume either gel cell or AGM, because true dry cells need a different type of charging. Are you maybe referring to a "dry charge" battery that you have to add your own electrolyte to? Could you point me to the battery you are using? I guess I'll be needing one pretty soon to replace my infernal spitting NH battery.
Thanks,,,
