Hi,
Bad moment this afternoon, after successfully wiring in the headlight relay mod, I went to take the K100RS out, turn key, dash
Lights all on, press button and nothing. No click from starter relay or starter motor. All other systems seemed to be whirring or clicking as usual. Battery fully charged and delivered 12.5v. All connections appear ok.
I have checked power continuity across the relay with the button pressed, power in and nothing out. I also checked power in through the connector block and that was ok. Last start up was 4 weeks ago after a spline lube and unusually it failed to fire after lots of cranking. When it did fire we put it down to a loose connector to the ECU or fouled plugs from prior slow running on choke.
So I think the starter relay has failed after the previous prolonged cranking. I cannot order another relay until Monday, so is there anything else I could check or do in the meantime? I was thinking of tapping the relay tomorrow just in case it loosens the contacts but don't really think that is a long term solution...
Many thanks.
Regards
Nigel
