A very long time ago I had posted in a thread that we should all install
 an anode on our trucks and trailers to extend their life expectancy, in
 my case tractors that are going to be stored for long periods.

In another forum thread I had posted pictures of engine bearings badly pitted from corrosion, this was electrolysis at work, had the engine been properly grounded this damage would not have occured during those long years it had been stored..

I have one probe of the OHM meter tucked behind a beauty ring against 
bare metal then as I poke the other probe into the damp earth the 
circuit has been completed, the meter registers a current is present, 
yes that is galvanic corrosion in action. My truck is being turned into a
 pile of rust as it sits in the driveway.

	hmm.. those big RUBBER tires should be great 'insulators' and not allow current to flow. It's why you're safer in a vehicle during a lighting storm. Resistance is not what you need to measure. Put the DMM in current mode, say 2mA and check for a reading, keep lowering the range( 200uA,20uA) and see it there is any current flowing. Electrolysis occours when there are 2 different metals and an electrolyte present. Lots of different metals touching each other in engines,tractors, well everything really. The electrolyte can be 'dirty' oil ( water in it ),cooling fluid( there's water in it),gas(tank has wter in it, MORE when ethonol's in gas) or condensation (water from air). It doesn't take much 'electrolyte' to get the reaction going and it happens 24/7. Easy but $$ way to reduce damage is to replace all fluids, 100% AND to keep vehicle warm( above 'dew point' ). Jay
