    Hey Guys
    My starter relay has decided to stop working.
    Can anyone tell me if they can be if you can pulled the apart to clean and inspect them?
    Her in Aus the new ones are quite expensive as most husky parts are, does anyone know if the Japanese bikes have the same relay? I can get a Yamaha one for a 1/4 of the price of the husky one. They do look identical just not sure about the wiring side of them is the same or not.

    Thanks

    Neil

    They're the standard relays (developed by Bosch 50 years ago IIRC). $5

    I can't remember the terminal numbers clearly but 30, 78, 78a... are 3/4th of em. If the yamie relay has the same numbers and form-factor... you're good to go.

    unfortunately there are no numbers on the old relay. It only has jideco on the top of it.

    I just cleaned it and found some more numbers. MS5F-710 12V 75N
    thanks

    not the numbers i was referring to. look at the terminals, usually embossed in the plastic. or there is a circuit diagram drawn on the side.

    also, IIRC (my 310 is in a garage buried in snow so I can't check) the husky uses the micro relays, not the standard "pool chalk" sized ones (my mistake). Take yours to an automotive store and get the right one, if the yamaha one doesn't work. still $5. wait, you're in oz- make it $15.

    full size and micro (note the terminal number differences).

    this looks like the one I'm looking for. not a normal open closed relay like you have pictured. I'm considering rewiring it so I can just use a relay like you have pictured.

    Sorry... i jumped the gun by not realizing it was the starter relay. (My excuse? I was hungover during my 1st post. ).

    Definitely a common relay; but compared to the other types (which a TE may have 2 or 3) much harder to source.

    BTW, one of the fuses is usually just a spare.

    Another big takeaway: pictures help.

    Once again, I apologize.

    I wouldn't rewire it; the nominal current is above the usual 20-30 amp rating of them.

    This relay also acts as a fused power distribution point also, in addition to being the starter relay.

    The yammie one is probably fine. Although less common, they are used widely- someone found one being used in a boat, for example. Usually they are Normally Open (sometimes designated N-O).

    lol Its all good Trenchcoat.
    I went to my local yammie shop and spoke to the spare parts guy and the workshop guy. Both said it should work even though the signal and the power for the switching magnet is round the wrong way.
    Bought it and fitted it, no surprise when it did not work (unfortunately this is my luck).
    I swapped the power wire and the trigger wire in the plug and now she works perfectly.

    Thanks

    You need to source one with the "Jideco" branding. They are expensive but made in Japan and the real deal.
    I bought a cheap version on eBay and it jammed on in the first few hours of riding. The cheap ones are really bad quality.
    The Yamaha versions have the wiring reversed compared with KTM but they are the same spec. Make sure the one you buy has the B and M labels on the correct sides. B means toward battery and supplies power to the starter solenoid. You can see the copper strap that takes power from the B post to the fuse and solenoid/switch connector.

    The M connection goes to the starter motor.

    hit all the lugs with di-electric grease. Vasoline or bearing grease or motor oil will work in a pinch. no anti-seize, btw.

    I was going to point out that a few pics of the relay in the ebay auction were labeled wrong (the batt terminal is always the one with the ring terminal on it AFAIK) but did not wanna confuse the issue- since I was definitely not doing too well in this thread.

    I wonder why polarity matters in the actuating terminals- maybe they have a diode across 'em to dissipate the back-EMF when the relay goes open. yeah, that must be it.

    When I plugged it in I was getting power to all 4 connectors. So I think you're right they must have a diode in there.
    Anyway we'll see how it goes, so far so good.
