Steve: Ray made an excellent observation and suggestion above and I should have recalled that scenario from a few years ago. The 03-07 VR made its connections behind the front pulley cover....the 08-10 VR connects behind factory left front air intake scoop. The only blown 30A fuse...which is the battery fuse...that I ever had to deal with in all these years, was due to a failed VR on a 2008 XB12 I had purchased. My apologies for not recalling that. I tested it as follows:
1-Replaced 30A fuse...started and throttled up motor with volt meter attached to battery terminals. As soon as the voltage would spike to above 15 DC volts...the fuse would pop.
Test yours.
