Gs450 starting issue.

[Guest]

My bike was running great. Was going at highway speeds lost throttle response and then died. Threw it on a truck got it home and a couple days later started again fine ran for 10 minutes and did the same thing again. Now I have no start at all. Voltage is fine in battery and starter solenoid. I think the flasher relay is bad but would that prevent it being totally dead? Or turn signal wires not being grounded prevent power? So confused here.

Have you properly cleaned carbs and replaced O-rings? See Basscliff site (member here) and you should find manual for your bike you can download. And there's more info on that site than you can imagine.

Is the starter turning?

[Tylermaslanik]

no nothing. no power to gauges or anything.

[chef1366]

Check the main ground cable off the battery.
Also the main ground for the bike comes off the battery. Make sure it has a good connection.

[Tylermaslanik]

my front turn signals are not grounded. would that matter? also the flasher relay seems to be bad. would that prevent the bike from getting power? at this point I dont care about starting it more so just where my power went. Seems to be a grounding issue but all my grounds look good.

There's a single fuse for the bike. Check it. If it is blown, proceed with caution (look everywhere for melted bad wires etc) and if warranted disconnect everything not needed to start and run...headlamp, brakelight,signals gauge lights ....and plug em in one at a time if the bike runs ok on a trial without em...and get a bunch of fuses until you find the short. There are better ways but I can't think of how to explain them right now.
The only thing "unfused" is the starter motor itself.

also, Your turn signals are grounded by connections inside the headlamp. should be, anyways..You see a single wire coming out the stalk, but the ground is on the metal stalk itself. .there's a ring connection that attaches to signal stalk where bolted in and that is plugged in to ground connectors inside the lamp casing. This method keeps signals "isolated "on rubber for vibration- that's why they don't ground through frame like cars do.. and, your signals won't flash if the bulbs aren't working. Check bulbs. Check corroded sockets.

fuse was fine. i checked that first lol. I dug a little bit more with a multimeter and noticed I have 12.5 on the battery. 12.5 on the leads of the starter solenoid but after that im not getting a reading. Starter solenoid bad?

[Gorminrider]

Starter solenoid bad?

or starter button or clutch safety switch or even a sidestand safety switch (on newer bikes).
Easy totest solenoid; apply 12v + to the solenoid field wire...it'll be the small one attached to the solenoid The big wires are the + switched and supplied to starter. Your bike should turn over, so be in NEUTRAL doing this and have blocks under the wheels if you are not on the centre stand.!!

or just disconnect the startermotor at the solenoid and your solenoid will "click-click" which doesn't guarantee it works properly but it usually is ok if it clicks.

Im not getting any lights on the dash though. Headlight wont turn on. Oil light doesnt come on when I turn the key.

[hank3fan]

I have an 82 GS450L. I can get my oil light and neutral light on but won't turn over. Another problem I'm having is that both lights come on without the key in the ignition.
I'm definitely a newbie and got the bike for $100 so it's basically a learning project. Sure hope to get it going though.

To hank3fan....

Head to this link and print out a few copies of the suzuki's wiring diagram. Start following connections at battery and see how it compares with your screwed up wiring. Look for evidence of tampering by a creative owner

So I went through the wiring and checked everything. Redid some grounds and now I can turn the key and at least get all my lights on, horn headlight dash lights etc on. My blinkers now will not blink. I took off the front ones totally and replaced the back ones with aftermarket. And they will only come on with the headlights turned on. If they are off blinkers will stay off. Headlight on blinkers stay solid. Also read somewhere that solid black wires can be hots? Lol makes no sense. Are the black/white the only grounds?

[Tylermaslanik]

Oh also I replaced my R/R and starter solenoid with brand new parts and still not getting anything turning over.

[tom203]

Which is it , lights ain't working correctly or "not anything is turning over" or a combo plate??
