Re: Bike wont start
The red LED is a general fault indicator that is turned on when the oil pressure is low, i.e. the engine isn't running. CHEC means that the cluster isn't getting data from the ECM, normally because the ECM isn't getting power. With the ignition on, check the voltage at the R lead on the eight pin SAP connector. It should be 5 V. You could also check the voltage at the W/R lead to the dealer mode connector. It should be something other than zero, but I'm not sure what. The problem commonly is with the side-stand switch or the kill switch. Will it crank? See the diagram on 7-10 of the service manual. Have you checked your fuses, particularly IGNITION?
