I went with the 40A upgrade due to the issues of last fall. It took me about 4 months to complete the prject but it was well worth it. Pics and notes can be viewed here...
And seperate pics are here...
ST 40A Alternator Upgrade
I updated all of the accessory wiring and added a 6 gang fuse box (sweet!). Slot 1 is for the switch on the dash (also new), 2 is for the left powerlet, 3 is a spare, and 4 is for the GPS. I also added a powerlet connector that goes directly to the battery (fused of course) for quick jump starts and charges to avoid removing the left side cover. I reconditioned all of the connectors and connections with dielectric grease and she now puts out beautifly.
I changed the oil for the 2nd ARX rinse with some more Exxon 20-50. I had to hunt the SL down and it is all now SG.
Additionally, I bought a new pumpkin from the late Bill Boyd that has only 9,000 original miles from it. It was from a crashed ST and was his spare. It really brought the bike together and made a difference it throttle response. Of course, Amsoil gear lube was added.
Let's RIDE!
