Won't start
 

I have 2 Identical 2005 Vulcan 800 classics. I swapped the Aluminum switch housings on the handle bars from 1 bike to other because I'm selling 1 and the condition on that 1 were better than the Im keeping. I never disconected anything just switched housings. Seemed easy enouph but now niether bike will turn over. Ive redone the job 6 times. checked the ignition fuse. My blinker's, horn brake light, all work fine but no fire. Need help. Is there a fuse under the tank ? I havn't checked there yet. Thanks. Update: Make sure the kill switch is snapped togeather tight when you put ot nack togeather.
