Simple electrical question

I recently went to start my 2n and when I turned on the key,I let the smoke out of the wire going to the resistor block from the key and a couple of other wires.Had no idea what the problem was so I decided to just rewire the whole thing. now, my question is, does it matter which side of the resistor on the terminal block the coil wire goes?? One diagram I got on this forum last night shows it on one side and another diagram from the same site shows it on the other. It looks like it really does't matter, but which side is correct??

Electricity and plumbing have a lot in common.

Consider that you had a 1" pipe carrying water thru it, you decided this was too much water running thru it, so in the middle you cut it, and put in a short piece of 1/2" pipe, thus reducing the flow.

That would be a resistor.

It wouldn't matter which way the current (water) was flowing.

The difference in the resistor on the tractors we are talking about is that right when you turn the switch on, and it is cool, it will carry full current nearly, but as it continues to carry current for a little bit, the wire warms up, and increases in resistance carrying less, restricting flow more.

Maybe I didn't go over simple.. {grin}

As long as the single wire to the coil is by itself coming out of the resistor it doesn't matter which side.

Simple electrical answer...

The resistor has no polarity, it doesn't care which way the electrons flow, or even if you put your battery in backwards (other things do).

Simpler answer, no it doesn't matter.

It only restricts the flow, whichever way.

I am fond of this one that I ran across recently.
I like it so much that I'm probably gonna wear it out!

the bottom line here is electricity could care less - as long as it has a path to follow it'll be as happy as a tornado in a trailer park.
