Installed a 12" LED light recently and rode for 500 miles in rain, sleet and slop for 3 days. Drove home in open trailer in monsoon rain storm then cleaned the machine up. The light was very easy to install and work perfectly the whole trip, BUT. Prepping the machine for winter storage and the light will not turn on. This is what I know: light switch with LED indicator is on, inline fuse is not blown, grip warmers work (works off the same machine fuse) and no visible breaks in the wiring.
I have a multimeter but am unsure how to use it correctly and I’m not sure if the light bar has failed completely. Looking for any help to use the multimeter or other means to troubleshoot were this failing.
