hi, just found you guys today and hope you can help. have a 2003 fat boy 100th anniv. only has about 1500 miles on it and took out battery for winter storage (we are in wisconsin). went to put battery back in today and test start it up and the efi went on but bike would not start and i started seeing white smoke and smelling electrical burning so i quickly disconnected the battery. called hd shops and was told i had a bad ground somewhere....couldnt find anything, was just ready to call it quits when i unplugged the tssm and found the problem! the plug-in end and the tssm were "smoking" and some of the tssm pins got "stuck" in the plug in end because they were melting. i have learned that the tssm part #68921-01B (new part # 68921-01D) is somewhere btw $120-$200 depending on the dealer. i found a used one on ebay that i can maybe get for about $25. is it a wise move to get a used one? i do NOT have the security system on my bike or any fobs so the security system is not an issue for me, would i be able to "marry" this easily to my bike? thanks, rick and michelle
