hm12460 53 #1 Posted May 21, 2011 Gentlemen, I'm looking at a 3112K801 312, which I believe makes it a 1990. Does this year/model have the un-regulated 3 amp charging system? Share this post Link to post Share on other sites
TT-(Moderator) 1,127 #2 Posted May 21, 2011 No - it should have the M12S Magnum with the 15 amp charging system. Share this post Link to post Share on other sites
