Desperate for help

[gasser]

My starter won't work and kicking that 300 is making the arthritis in my right knee flare up. Bike is a 2018 ec300 that I bought used and I suppose all the mods to the starter had been done by the previous owner because it always started great until recently when the started didn't disengage upon startup and that fried the starter relay. I have since replaced the relay and the starter motor. When I short across the two large terminals on the relay the bike fires right up but I don't even get a click when I use the button (it's new also). Even shorting across the black/white and yellow/red wires that go to the button does nothing. I'm stumped. Is my new relay bad? Could the diode module be bad? Thanks in advance for any help you can be. Ken
