Hello all, I got my ‘76 CB550f Back from the shop and there seems to be something wrong with the m-unit. The input side of Aux-2 is flashing, all other lights on the unit are off. There are also some times that the m-unit will not power up at all. Seems random. On the occasion that it does power up properly, I can use some buttons by just touching them and not actually pressing which leads me to believe it’s a grounding issue.. the answer to all this probably lies in knowing what a flashing Aux-2 means. Thanks in advance!
