G’day lads,
I’m new to the Yamaha family I picked up an 06 apex for a screaming deal but I’m starting to see why it was so cheap. I had code set 84 and 42 come up on the cluster and a constant flashing yellow light. I bypassed the tors to eliminate that for now during diag, checked the pickup for the speed sensor and cleaned the ribs to ensure proper signal all ok there. Checked speed sensor found broken wire insulation at the sensor where it bends figured some corrosion worked it’s way down the line into the sensor causing no pick up. Installed new Yamaha sensor and still no speedo, disconnected battery over night and tried running on stand for about a minute straight still nothing. When sled warms up it’ll stall but when cold it’ll idle. Checked cluster to see code set and found 11,15,22,30,81,84 but no 42. I’ve seen guys say that there’s relays that may go bad or ecu I don’t have err 01 which I’ve heard means ecu has left the party. Any help would be appreciated
