srx electrics

[Chris]

Hi I have been wittering about this one for some time,any further help appreciated.My srx has been going well in daylight but fails when the lights go on.The battery stays charged for varying lenghts of time and then goes flat.It goes flat pretty quickly when the lights are used.I have removed the battery and fitted a battery eliminator.The bike goes well but no trace of horn,indicators lights etc.I guess that it is doing little or no charging.Any suggestions,apart from full immersion in a skip.
Thanks
Chris

    Ignition circuit and charging circuits are entirely different.

      Check your charging coil resistance... there are two different pickup coils that run off the alternator.

    One runs ignition...

            It aint that one.     Check your wiring diagram and run resistance and continuity tests on the charging circuit.

  Bad ground, loose connection, caused by corrosion or vibration, or a failed component will expose the fault very quickly.

  Unlike Humans, volt/ohm meters seldom lie, and are entirely logical.

  Good luck with it.

  It is fun because it is pure logic, and when you solve the problem you will be proud of yourself and gain confidence for the next hurdle.
                             Such is the nature of motowisdom.

PS.    Never forget the Beatles song...       and get by with a little help from your friends.

   There are many much closer than I am who will offer their help on this, if you ask in the proper spirit.

        PS2.     When the old fart fixes it, buy him the beer of his choice, and try not to repeat the identical problem to him again, otherwise, he will think of you as an uninspired punk unworthy of his time and tutelage.

    Over and out.

  PS3.            As a last resort... farm it out to someone else, shell out the cash, and learn nothing.

   You make the call.                                It is yours to make.

Hi bikeseamus, sounds like you know what you're doing. Can I ask about my indicator system headache for my 1986 SRX600? I simply need to know how it all connects together. I have the flasher unit with two spade terminals, that fits behind the steering head. Unfortunately the connectors have corroded off, so I don't know the colours/polarity, so ideally I need a description of how this connects to the other components of the flasher system. A big ask, but if you could describe the wiring/components that would be brilliant (studying the wiring diagram and badly photocopied photos gives me a headache). Regards Rob

   I regret that I gave my service manual to the buyer of my 3rd SRX, but any corrosion on the contacts of a flasher unit will cause it to go bonkers, if all else inside is in order.

   All flasher units are rated upon how much juice they take to flash, and the speed in which they do so.

  I have substituted Buell turn signals on my Vmax, for instance, and now they flash (cycle) much faster, because I retained the stock yamaha everything else.

  Flasher units are only good for so many thousand cycles of flashing, and they get tired and fail.

  As they will say in many service manuals, substitute a known functioning unit, and retest.... that is true of CDI units, flasher units, and about any electrical component on the Space Shuttle as well, and it requires no testing tools or the incumbent knowledge/training/experience required to operate them.

  Also keep in mind that flasher units are NOT motorcycle specific so much as they are amperage specific, and an auto parts store near you may be able to supply you with a favorable replacement of identical juice draw requirements.

  All units in the USA have the numbers stamped or printed right on them, so match up the draw specs and you should be IN THERE... as they say...... assuming the flasher unit is your prime suspect.

  A bad ground an any part of the circuit will play hell with your diagnosis, so you should very carefully clean every single solitary electrical connection in your bike from time to time, and seal them with dialectric grease to preclude further corrosion or poor continuity related problems.

  I am sure a good spirited person reading this who is in possession of the juice specs for your flasher unit will respond and add to your information, if needed.

  I know I shouldn't always give away my service manuals, because I keep returning to my favorite bikes, and have bought as many as four different identical service manuals for my bikes over the years.... because I see another one at a good price and jump on them like a dog on a bone.... but I guess I'm silly or stupid or self deceptive enough to keep doing it.

  I guess if I laugh about it..... no harm done.
                                                                          Sorry that's all I can offer without a service manual, but I have a feeling one of your countrymen will now pick up the ball.

  Seems to be the nature of this fine site..... cool deal for all.                        Good luck with it, Buddy... I think you will prevail.
