If you were using the locomotive boiler, etc… as a ground, and just running positive wires (DC circuit) around to lighting and or other things, would or could, given the right circumstances, this cause some type of electrolysis in the boiler? Is there any proof, studies that have been done?
Hah…you think too much!
Water pipes are used for home AC as a ground. The motor block on a vehicle (DC ) is used as a ground. Just take the suggestion and run with it. Stop thinking and build as this thread will open up a whole other can of worms from the expert posters. I think we may have been twins but separated at birth.

You would have to use the water as a conductor to cause problems. dare I say it ROOSTER is right!

Yah see even Eric thinks we may have been twins that were separated at birth Randy !
I figured as much, typically parts being plated/striped are suspended in the liquid forcing the current through it. I can’t really see how on one of our models that something could occur to cause that, so consider my curiosity quelled.
Brother Roster! How could something this tragic happen!
This thread is dead!
Now get back to work !

For electrolysis to work, you would need a voltage, or difference in potential. You also need current to flow from one type of metal to another type of metal through your electrolysis compound. So running power through your boiler jacket, or shell, should not fulfill those requirements.
Not so fast David…
While you espouse some truths about electrolytic corrosion; in our train world you don’t have to provide said DC current, dissimilar metals chemical interaction together with an electrolyte (water in our circumstance) creates what is coined “self-induced currents” otherwise known as galvanic corrosion. Galvanic corrosion is often grouped into the concept known as electrolysis.
Bronze, brass, steel, cast iron, copper, copper alloys, tin, lead to name those typical of a model steam engine are susceptible to galvanic corrosion IMO. Yet plain old water and especially distilled water makes a poor conductor! With steam there is little hope for galvanic corrosion, yet acids and salt water electrolytes work harmoniously with dissimilar metals. In the end galvanic corrosion is not really a problem in our train world.

That’s why I didn’t mention it. And, its a problem, unrelated to the question of using the boiler shell as a conductor for the headlight power.
Leave the over thinking to Devon!

David I do reserve the right to add marker light too. Why stop at head lamps? (http://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-wink.gif)
Yea, why? Or, why not. Ore, Wye Knot?
Rooster says this thread is dead, so why not beat it a little longer. (http://largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-wink.gif)

Sure wye not Maynard.
You are the one that posted after the question was answered and I called the thread dead. You had to post on it only to find responses against what you had posted.
That brings me to why did you post?
Was it for count or thanks or was there another reason Captain.
Vasilli is dead!
I posted to answer Randy’s question. That’s why. I couldn’t care less about my post count.
