« on: January 13, 2018, 07:35:11 PM »
Hi all quick question . Checked the clutch switch all good how ever I only get 4.75v on the black/ orange wire on the loom side of the connector Question is should I get a 12v reading on the black/ orange wire from the ECU to the switch connector

The supply to the switch is from the ECU.
A lot of electronics operates at 5V.
As this is a "status" signal it may well be 5V.
Are you able to check the sidestand switch voltage. Also a "status" signal.

 Hi
Why are you checking switch,  you haven't said you got a problem?

I'm in no way any electrician but thought that I share something I learned in the past. If you remove the starter relay and check the pins there so that you hit the starter button you should be able to see one of the pins to become 'hot'. This pin is the one on the line of three, cant remember right now which one. But this comes from the ECU and if its 'hot' then you have eliminated all those additional checks of clutch, side stand etc. If its not giving any reading then you need to move 'back' to analyze those other things preventing ECU to send the signal.

Grizzly I found the neutral light was a bit intermittent, so I wanted to clean and protect the connector.
