It should come on with ignition on and go off when you start the engine. OK, mistake here—Light on with ignition on, then should go off
Also this is controlled by the ECM and sent EOT light comes on when the meters receive the info to do so via the bi-directional serial data line.
After 2013 models have the serial data line. To the ECM is Rear wheel speed sensor data, and to the meters is High oil temp indicator signal, Engine speed signal, and Fuel pulse signal.
Quick look at the manual yesterday said to check the temp sender. I can look for details later.
It may be related to one of your other problems. I’ll have to look at the book and the wiring diagram.
Do you have a service manual? You need one.
I am sending you a PM
Thank you. Yes, I just picked up the 600 page service manual. Thank you for guiding me through the electronics. My 71 CB750 is much more simple and mechanical.
