Answered my own question on where the circuit breakers are - the main C/B is actually "behind" the flasher (in relation to the rear of the bike). The tab to pry is on the "left side" of that assembly. Figure 7-42 was most helpful (in the manual)
Am I correct in that if everything else is working well (lights/horn/speedo/etc.), the main C/B is just fine? If so, this issue kind of has to be the flasher, correct?
So is the Novita' EP-36 what I need?
