    Sms 630
    Hi everyone,

    Recently my SMS 630 dash and lights (signals, brake, headlight) died while driving. When I turn the key from off to on the dash and parking light turn on briefly (approx 4 sec) but then die and the signals/brake lights/horn do not work. The bike runs ok otherwise.

    I checked and changed all of the fuses, as I expected fuse 23b (aka fdc) to be the culprit. Thus did not resolve the problem. I checked the relays, they are good, however I now believe the relay 14B to be the problem, and possibly is not receiving power.

    I am hoping someone can give me some insight of what the problem might be before I start to take apart all the wiring. The obvious failure points along connectors and under the tank are all good.

    Thanks!
