mc28 electrical problem

tvhead » Sun Aug 14, 2022 10:04 am

Good Morning.
I have an intermittent problem with the warning light on the small screen. It started with a brief flash followed by a longer red light then no warning light. At no time did any error code show on the screen. There was no change in the bikes performance.
I changed the battery, cleaned the fuse box and fuses and the fault cleared.
I rode the bike for 250 miles with no warning light showing, but the fault ( red light ) showed again.
I then checked each component that could have caused an error code to show. I unplugged the throttle position sensor, switched on ignition and an error code appeared on the screen. The power valves worked properly with the engine running running and the multi meter showed 14.4volts.
The temperature gauge worked properly.
Oil tank sensor worked properly.
I then cleaned all the multi pin plugs.
The fault is still there.
Is there anyone out there who has any ideas about possible causes for the fault as I have run out of ideas.
Thanks
