    Intermittent starting issue

    Hi All, Been a while since I posted but I do visit often to see whats occurring.

    Anyway, hoping to get some help with a problem with my 1999 bird (coming up on 140 thousand miles). On occasion, I hit the starter and get nothing...no turning over, no clicks, no buzzing....nothing. However, if I immediately try again it will most likely fire right up. Sometimes it might take 3 or 4 attempts with nothing happening, but it always (so far at least) eventually starts just fine/normal. This has been going on for several months now.

    Thinking it was an issue with the starter button, I have taken it apart and cleaned the contacts etc several times. After reassembly it seems to be fixed...but eventually the issue returns. I finally decided to replace the whole right-hand assembly...again, it appeared good for a while but the issue has now come back.

    Anybody had this issue or have any thoughts/suggestions? Its confusing because it happens so randomly. I'm thinking of looking at the starter motor (original unit) but wanted to seek help here first.

    Thanks in advance.

    Re: Intermittent starting issue

    Check the clutch switch, neutral switch and side stand switch. Also, the clutch diode.

    Re: Intermittent starting issue

    1. Side stand switch: engine idling in neutral, extend side stand and engine should die.
    2. clutch switch: remove 2 connectors at clutch. Test switch with multimeter, and/or jump connectors to temporarily eliminate switch.
    3. neutral switch, if green dash light works, switch is good but diode may have failed.
    4. diode. Haynes manual gives test procedure, although mine fails this test but works ok. I bought 2nd diode, then figured out dirty clutch switch was problem. If you need diode I can mail you my extra one.
    5. Faulty/ damaged wiring??

    okay, thanks a lot.

    Presumably for (1) you mean engine in gear?

    I am off work for a few days over thanksgiving so will test these things. I'll report back. Yes, I'm thinking that faulty wiring could be the issue (given that its intermittent), but I hope not as that could be a major PITA.

    Thanks again fizzy.

    If anyone has any additional thoughts for what I should look at, please chime in.

    Re: Intermittent starting issue

    Sorry, yes, (1) engine in gear.
    Also, I assume that when you turn on ignition, everything comes to life except starter.

    yes, everything totally normal apart from silence when hitting starter button....but then press it again a time or three and it starts.

    Re: Intermittent starting issue

    Hmmmmm I'd wonder about the starter relay as well?

    But before that I question how you are cleaning your switch? If you scrape the contacts clean and leave it as bare metal, the metal will foul up quite quickly and you can end up where you started. Are you putting a little dielectric grease in when you're finished? If not I would recommend you do?

    Thanks. Ya i used dielectric grease. But i have also replaced the whole switch assembly and have the same issue so i don't believe its the switch.

    Re: Intermittent starting issue

    All of the above but what caught my eye was
    coming up on 140 thousand miles
    I had a 'failure' in my ignition barrel. Mine was due to corrosion, cleaned up OK but there was wear showing at @100K miles.

    This is easy to get into and parts are available but you do need a set of security bits (the screws have a round pin in their centres making access with 'conventional' bits impossible)

    Re: Intermittent starting issue

    My bike had the same symptoms which was cured by replacing the starter relay they are cheap enough and a simple job.
    But with all electrical problems it can be a plethora of things and you can bet your bottom dollar its always the last bloody one that cures it !

    Thanks duck. I'll prob try the easy stuff above first and then look at this if I've had no luck. I'm guessing the very dry conditions here (vs southwest UK) mean i likely have less corrosion.

    Absolutely I only mentioned it due to the wear that I saw (as opposed to the corrosion) but thinking about it, if there is wear there could be a bit of arcing going on .... anyway not likely.
    Just throwing another one into the pot, the cables at the bottom of the ignition barrel can become separated from their solder blobs if the loom is tied down to tightly (pulls when on full lock) but assuming that your ignition stays on and it is just the 'starter' that is playing up then this is also not highly likely, but it will produce an intermittent fault. Again you need the security bits to get in to check this but you don't need to dismantle any more just drop the cover and use a small mirror to inspect.
