hi all, nubie here so forgive me if this has been asked and answered. on my '07 fatboy s.e. this morning a trouble light came on that i have never seen nor does the manual speak of. it was a red or amber circle with graduation marks like a spedo or tach with an arrow on the outside pointed down to it. can anyone tell me what it means? it only came on for about 15 seconds. thanks, gonz.
