    Starter solenoid / relay

    Have a 05 FXWG that would not start, no click from solenoid but could hear relay clicking. Checked voltage at the terminal from relay to solinoid and got battery voltage. Took solinoid apart and all looked good, as a last resort be for buying new starter And solinoid I jumpered direct from battery to solinoid and bike turned over. Grabbed a solinoid off another bike and that worked too.

    So question is why would I have battery voltage at solinoid if the starter relay was bad? Weird huh?

    That should have been " grabbed another relay off another bike" not solinoid

    Scotty, nice to see ya. You said you grabed a solenoid off another bike, then you mention relay. If you meant relay, then, yes, it was bad...

    Don't force it, get a bigger hammer.

    scotty - a relay is similar, in a lot of ways, to a solinoid in that it is an electro-machanical switch (yes, the solinoid does other things as well).  The input to the relay from your switch is a low amperage wire - the input to the solinoid needs to be much higher amperage (draws more watts) - if the relay doesn't put out enough amperage, it still might read 12v but like using your bike battery to boost a pick-up, it may not have enough amps to get the job done.

    Ya I figured that it wasn't getting the right amp's but no where could I find a spec for the required amp for eather the throw out or the hold open coils in the solinoid. I guess that the relay contacts must be burned and like you said wouldn't provide the required amperage to the solinoid coils.

     

    Thanks guys
