I have my 1/0 ga ground from the battery to the frame rail under the exhaust hanger. I ground a nice clean place with my angle grinder and attached everything nice and snug.   

However, since it is underneath the car I have slabbed vasoline all over the connection. Two years (any NO driving) have netted me a nice clean connection still but I wondered if there was any consequences to this??

probably not , but, something better would have been liquid electrical tape. it comes in a couple colors and has a brush on the lid.

I would think it would hold some moisture on the connection leading to electrolysis. I like the heavy cosmoline based corrosion inhibitors.

Vasoline sure works on battery connections. I use it on any new connection to my battery. Again, it must be clean to start with. It takes very little, as the engine heat melts it where it runs into the smallest places. It attracts dust but dust is better than corrosion and resistance and dead batteries.

The reference to two years of no problems answers the original question.

Yes but I hadn't driven the car at all.

Doesn't matter if the car was driven or not if the battery and all the components were connected and ready to go. You still have that small drain with the ignition off unless you have a battery switch. Even then there is venting of the battery, etc. I realize you are talking about a remote connection away from the battery. The corrosion occurs due to the sulfuric vapors reacting to the exposed metals. Other corrosion can happen due to salts on the roadways. electrical connections are not the only things affected there.

I still say two years is a good omen. Good clean connections and keeping the air from the metals that will oxidize in same is always good practice.

Thanks Joe! Just got finished installing the replacement 300/2000 amp cut off switch as well :)

I use vasoline on battery connections, and I slather up the pinswitches with vaseline when I install a pinswitch under the hood. I used to not do this, but had many pinswitches get rusty and not work. The vaseline works pretty good. I've also used Mobil synthetic wheel bearing grease (thick red grease). It doesnt melt like the vaseline does. I tell customers that they can maintain the pinswitch by applying grease or vaseline at least once a year or so, or as needed.
