So where I'm now confused is as to how that is better than the bypass? If there's no resistance at the ammeter, then where would the increased load come from?
Break this up for me. So where I'm now confused is as to how that is better than the bypass?
If your question is what I think it is, do the same excercise with your finger for MAD's figure B.
Start at the alternator and follow path the current must flow to get to the main junction (the welded splice).
How many connections are there along that route?
Is the route longer or shorter?
Are the wires larger or smaller than original?
If there's no resistance at the ammeter, then where would the increased load come from?
What ammeter?
When did your finger cross over the ammeter?
