so i have bee reading about the 40 amp alternator upgrade some then yesterday the ST left me on the side of the road. after about an hour of pushing (thanks st1300 owner in loveland) i got it to work. turns out that it wasn't charging, the battery voltage was about 10 v when i checked it. so put it on the charger and went in to my desk to work. at lunch time i came out and it was about 12.5 v so i turned the key and fired it up. the voltage took a slight drop (when cranking) then held mostly steady but was continually dropping - sounded like a sure fire alternator to me, which is a bummer because i neither know enough to do the 40 amp swap yet and i dont have the cash. so i patched together a network of batteries and got her home this morning, voltage of the pack before leaving was 13 v voltage when i arrived home was 12.25, so i dont think that i did any additional harm to the batts.
any way when i began inspecting things this morning - by the book. i noticed some wires in the big white connector were a little crispy. looks like there was a bad connection in there and it heated up to the point of melting the connector.
i have run through the current draw test and it checked out ok. and i will do the reguated voltage test when the battery comes up to the proper voltage (charging currently) my question is what could have happened to the charging circuit de to the connector meting and jumping to other wires and should i have any fear of hooking up the battery to do any other tests?
secondary question is would it be worth trying to fix the 28 amp system or is the 40 amp so much better that it is worth my waiting to get the ST going again to save up the dough?
also i have found a lot of info about the upgrade but does someone have a complete list of whats required and a good source for reasonably priced parts?
thanks all, really appreciate the help and advice on this forum.
the bike is a 1993, with very few electrical farkles - intercom system and stock headlights and such as far as i can tell, and 32000 on the clock.
