Hi all, I recently reentered BMW World after a short hiatus in Harly world. I bought a used 2015 R1200RT(Previously owned an R1100RT) . At the same time, I purchased an Advanced BMW Charging System. After time I attempt to use it, plugging it into the BMW console built into the fairing and using the BMW plug, the amber light flashes and that is it. It never appears to begin delivering a trickle charge. Is the charging unit bad?
