"Weak charging system? - the solution"
I don't have the computer chops to link directly to moe's post, but it's pretty easy to find.
Finally got around to this task as a new battery was in hand. Results - 14.5 volts at idle, just after start up. Me likey. The best I used to do was low 13s.
I'm a very happy boy. If I had to do it again on an 05 Speedmaster, I'd pull the swing arm and do it on a bench. I favored splicing into the wires just out of the regulator / rectifier so as top avoid the plug and socket just downstream.
A little off topic - Bought a Walmart store brand battery for $57 the other day. In very fine print on a bar code sticker was the date Walmart put it on the shelf, which helped tell me which were freshest on the shelf without pulling the box open. The battery itself was one month old. The battery is an AGM with the acid added by the end user. On the box - "Made by Johnson Controls." In fine print on the enclosed directions - "a division of YUASA batteries." Life is good.
