    Starter cuts the power off...

    This just occurred, went to start (battery good and on trickle), everything lights up, fuel pump works, go to push starter, everything dies. Checked wiring and connections under seat. Everything lights up, go to start, same thing, everything dies. Starter connection? Relay?

    Ideas?

    Check ignition relay if the battery is OK. But maybe battery lost juice and voltage drops too low when the starter is trying to crank the engine so relay disconnects. Try connect a good battery, maybe car battery if you have one and test it. Or just connect voltmeter to the battery and see how low voltage drops during cranking the engine.

    best thing is to have battery load tested at any auto parts store. it my read fine but under load drop voltage.

    the yellow starter button is fused into the headlight circuit. check the headlight fuse for starters.

    Thanks guys! Iíve put the battery on a real trickle charger in lieu of the small battery tender, and Iíll have it load tested.

    Question: assuming the battery turns out OK, what should I look at? Does the starter relay kill power to everything for a time if itís going bad?

    This is interesting; Iíll let you know what I find on the battery. Itís rainy here so no loss. Thanks again!

    dave: typically no is the answer. all it does is receive a voltage "trigger signal" from the switchgear mounted starter button....then it substantially raises the voltage signal and sends on its way to the starter assembly solenoid. that's the whole purpose of the relay. having said that i'm seeing starter/key switch/ignition relays starting to fail at alarming rates now mostly due to age. for the $6 price of admission i just simply replace with new. what ricky suggested always highly recommended. these XB's are hell on batteries. an odd fresh electrical gremlin rearing its ugly head in conjunction with start up issue? almost always the battery and/or cable connections.

    Perfect advise so far, you've got some qualified help already

    Let me add that a loose or corroded battery connection will do that exact thing. No matter what, this will be easy do diagnose if you have a voltmeter.

    Put it on the battery. You should have >12.5 volts. Press the starter button and you should have >9.6 volts.

    Great additional info. I checked the connections first, and insured they were clean, dielectric greased and tight. I know how the relay works, I just couldnít figure why, after the power went from the electronics to the starter, and the starter failed to turn over the engine, why all the electrical indicators went dark for a few minutes. Battery Iím assuming or a faulty relay?

    The battery showed good voltage, but the amperage was below spec on the load test. The Autozone day didnt carry a battery with the recommended starting amps. This something I have to go to the HD dealership for?

    New Relay too or......?

    below is the link to the best battery you'll ever find for XB's at the absolute best price. 220CCA's which is outstanding.
    https://www.ebay.com/itm/DEKA-ETX14-...MAAOSwOFBafYkT

    all 3 relays the same and also the same for all years XB's. factory part # is H-D#31522-00
    cross-overs are: 2005 ford focus a/c relay
    Panasonic CM1-D-12V $4 each online.
    NAPA V11214 $5 at napa
    NAPA v11190 $5 at napa
    Duralast part #19283---autozone/pepboys/etc etc

    you're welcome.

    Thanks all!!!! Fantastic help; Iím replacing the battery and Iíll look at the relays too; maybe go ahead and replace them if theyíre easy to get.

    Real thanks for the relay numbers and options; thatís very useful; props!!

    BTW, Whatís the difference in the two NAPA part numbers? Thatís kinda my go-too round here.
