83 gs550esd died while riding help..

[David_510]

no i did not check it with the AC setting. i stopped right before that step as it was going on 8 and i didn't want to make much noise. i will test it tomorrow when i get home from work.

Also im going to wire my r/r directly to the battery and out of the fuse box and see if this makes a difference. Btw, before this problem the bike ran fine, so im thinking it is probably a pinched wire somewhere shorting out?

Again did you jump the bike with the motor running on a car?

Hi,

Yes, the stator output should be measured in AC voltage and should be around 60-80vAC or so. They should all be equal too. The same for the resistance measurements, they should all be equal and somewhere between 0.5 and 2.0 ohms.

These should help you understand:

Yes chef I havejumped it with a running car. Did not know it would hurt it. I answered ya in an earlier post.

And bass, I read most the papers and my ohm test was 1.3 on all.

[BassCliff]

Hi,

The resistance test will tell you if your stator is bad, but it won't necessarily prove that your stator is good. The active test (AC voltage) is much more telling. Keep us informed.


Thank you for your indulgence,

It will fry your charging system. Too many amps pushing through that itty bitty R/R and shunting at the stator.
Jump it with a non-running car.

Ok, so i had some time to work on my bike over these past few days..

Sigh.. No progress, all it has done is stumped me (and my dad who is a harley builder)

So maybe someone can help me.

I am charging, and good i might say 15.2 volts and it drops down to about 13.7 once the bike is warmed and the battery is at a full charge.

So now here is a breakdown,

it charges!!!!
I went over the wiring harness, taped up every loose connection and cleaned them...
Started the bike ran great, did all my charging test with it... let it idle for a bit, went to go out for a short test ride, get out of first gear and hit second and it just dies, but than quickly restarts from compression..

Ok so i continue my ride, about 5 miles later, dies, won't restart from compression. I hit the starter button and it kicks over and kinda pops but not starting fully. So i turn key off back on, hit the button, it fires and i go. I ride another 10 miles without it doing it anymore.'

Get home, shut it off. Walk in side BS about how it died and blah blah blah, Come back out to put it away, HIt the starter button bike fires right up runs for 2 seconds dies... HERE IS THE WIERD PART.. I hit the starter button again and it acts like the battery is dead, barely barely cranking over and then it stops cranking over and if im still holding the button the line from the battery to the solenoid starts smoking.

But then, about 3 minutes later after trying to solve it with no success, it cranks over without a problem, so i hit the button one more time after it cranked over good and back to this acting like the battery is dead ****. The battery is at 12.9 volts with bike on 13.2 when off. Fully charged.

So it does this where it cranks really fast for one hit than acts like it won't crank the next hit of the button..

But while trying to diagnose this, don't forget about it randomly dying while riding. Just goes from 6500 down to 0 rpms in a blink.

[JEEPRUSTY]

A clearly failed charging system.
It appears OK in static tests but is not able to charge the battery when in motion.
Real world situations require that charging system produce a specific range of voltages.

If your bike was doing things properly and you were above the 5k rpm threshold your battery should be charged.

It is not working coorectly

[David_510]

If, the charging system isn't working correctly, why is my battery fully charged after riding? It had enough to crank over the bike perfectly fine when it died just recently and the time before that too...

My charging system is putting 15.2+ to the battery than drops to 13.9-14.2 after the battery is full at 13.2 ish...

I mean, if it wasn't charging the battery the battery would be dead and i would not be able to start the bike and continue riding it for another 10 miles.

Hi,

Try a new starter solenoid. You can pick up a generic unit pretty cheaply from a place that sells riding lawn mowers.


Thank you for your indulgence,

BassCliff

[mike_of_bbg]

I agree with BassCliff. Maybe there's an issue with your solenoid holding back the starter current? A new lawn tractor solenoid is pretty cheap and it would eliminate that possibility. Make sure your cables are in good shape.

You are charging, but your charging system is not working properly in my opinion. 15.2V is too hot. I'd look into replacing your R/R with a better quality one. Lots of info out there on models to choose from. Yeah I know "it runs OK and charges the battery", but your issues with over-charging are two-fold:

1. Charging at over 15V can boil out your battery

2. That high voltage takes a toll on your digital electronics, like your ignitor - and there's no easy/cheap Dyna S for 16V 550s.

My $.02 anyway.

david 510,re post #24.Did you put battery on charger after this ride and see in minutes how long it took for the charger to fill battery?I do this still even as my GS is fine now,it gives good reference point for battery condition.Yes voltage reads are good too but ,this gives even more data and ensures a full battery at next ride. This little procedure will take the doubt away as to:Has the battery Really been charged while riding.Someone on GSR has quote:to measure is to know,well put ,indeed.Data is good.

[David_510]

The battery fully charged up in about 30 minutes after I put it on the charger, maybe less but when I went out about 30 min later it was showing 100% and read 13.2.


I was thinking starter solenoid too. It is the only thing I can think, but will a starter solenoid cause the bike to just cut out and die?

[elrico]

Battery recovery time if,are you useing a nice low milli/amp type like 800ma or so, then 30min recovery battery time to full was somewhat good considering all the many starting attempts and system loads,lights(Big}and all ignition demands,etc. and if you rode what,approx. 15mi(yes or no?) Machine dead stall out @6500rpm in 2nd gear,huge engine vibes,much stress ,may have shook loose or moved/rubbed electricial connecter,try to test ride more conservatively for personel safety.Yes the stress/test riide may have revealed another fault,but may be part what is the ongoing problems.These problems w/bike are irksome,dont jack yourself up while working on it,esp.the test ride part.you do not have a safe reliable road machine...yet,it will take time to resolve,and many knowledgeable GSR forum members are responsive to this,very much so.

Downloaded manual for gs550es today,have owned this Suzuki 16yrs.w/aftermarket manual.This is my first capable computer and service provider ever.Manual is the real deal. Find a way to put this in your possesion, you will glad you did.Dont put this off it is GREAT info.
