I pulled the seat off after a ride last week, maybe 1/2 hour of seat time. I was attempting to wiggle the relays to see if I could make my headlight misbehave ( This season, I placed a 20W LED H4 replacement in there...)
Anyway, I noticed that the rear-most relay seems to be notably warmer than any of the others. The rear one probably carries the most continuous current, since it's powering the FI pump, coils, and injectors. I'd guess about 8 or 9A, but I have not measured it yet.
