Just purchased my first wheeler, a 00 xpedition 425. The guy said he just changed the voltage regulator because the lights weren't working. Got the bike home ran fine the first day and then the next day it wouldn't start with the ignition so I pull started and it fired right up. Started smoking and I pulled the front end off to see the voltage regulator burnt up. I know a new VR is needed but what other diagnostic do I need to perform to see what burnt it up before I burn another new one as this was brand new the guy said.
Thanks for any info
