Battery / starter motor again!!!

Yes you could be right. Isnt thee another relay of the same vsriety on the bike i could swap to confirm the threory

Well back at home, ive just thrown it on the GS911

No fault codes stored at all ..

Battery voltage 12.62 press the button and clunk clunk

The solenoid is energising and throwing, or trying to throw the bendix forward.

But there is nothing to make the comutator spin ??

I'll strip the starter later and put it on the battery direct, and see id the bendix is comming forward, / spinning

Mart
 
starter button / kill switch?


Had crossed my mind, but to occur exactly the same distance back as the journey out,?? I'll see if I can access my logs from this morning and see what they say
 
Spent the evening looking at this in some detail...

Checked the Batt voltage 12.85 no start just clunking from the solenoid ..

Started to take the battery out, and thought the neg terminal looked a bit dirty .. so gave it a clean and recconected

everything ... 12.85V pressed the bitton and it span over and started... :) could it be that simple...

I turned off, hooked up the gs911, batt voltage at 12 .45 now pressed the button and clack , clack, clack nothing :(

so starter out, stripped and rebuilt, ( couldnt get the bendix off the shaft, but put the screwdriver through my

thumb!! Ouch!

Reassembled the starter and tried straight from the battery ... bendix shoots out and spins... every time ..

It does feel a little notchy on the shaft, but i cant see that causing a non start...

Only odd thing about the starter. The bendix appears to be connected to a large type of one way bearing,,, should

this bearing rotate around itself or Just the bendix shaft

Catch 22 now, i need to start the bike to find out wht it's stalling when comming down through the box, but need to

find out what is causing the non starting :)
 
A 0•4V drop in such a short period isn't that unusual, it takes time to recharge, especially if headlight etc are drawing most current.

It is sometime since I pulled a starter to bit's, I think the bearing rotates around the shaft but I'm not 100% and will happily defer towards others.

Normally, stalling is due to either losing spark or fuelling my first inclination is to check tps and cables, although I'd expect gs911 to show that fault up.

Contacts inside solenoid may well be burned and its not bridging the load circuit!

hence clunk clunk but no turning

Could also be a dead circuit on the starter armature
 
Mart, the more you describe your symptoms - especially the stuck bendix gear - the more parallels with my woes from a couple of months back. As you know, a new starter cured all my issues.

Instead of buying a starter, if you have the time try taking it to a local auto electrician and see if they can rebuild it. They will say no on the phone but take it in bits so they can see the guts and that it is just a normal starter and not some motorcycle magic and they will probably at least have a look. It should only be a few days if they can get the parts.

edit, forgot to add on mine the pinion gear was stuck in the "engaged" position. I am not sure if when the engine started it got spun out the way but it took a lot of leverage to free it off. If stuck then it cant be good for the starter.

I thin i may just bite the bullet and get a new(er) one .. i'll see whats on the bay, and Motorworks etc

if not i may go arrrowhead

Yes that would fit the symptom of the intermittant starting

I cant get into the solenoid, so cant tell whats going on in there

Looking at that video, it looks like my proble, the solenoid is throwing the bendix forward, but its not rotating ..

oh well lets go shopping :D
 
I think you need to sort out the cutting out first. A faulty starter is unlikely to cause the engine to cut out, whereas faulty electrics would cause the engine to die and not restart. Check every connection, especially on the engine as it sounds like it happens when it warms up after a few miles but is OK cold. Clean any fuses. You mentioned a potentially dodgy battery connection, check the other end as well, they could all be in the same condition.

Heat could affect the coils causing it to cut out, but they wouldn't affect the starter, so unlikely, same with the injection.

You need to sort out the cause, not the effect (the starter not working is an effect of another fault).

Indeed you are correct, but i need to be able to start the bike first to find the cause of the cutting out

I'm offf today, so will go have a good look in a minute
 
Good luck, intermittent electrical faults are the worst.

After you have cleaned all the main earths and power feeds, I would move on to the switches, ignition and cutout and the wiring up to the bars which can cause a problem with the constant flexing caused by steering.
 
As above, a dodgy starter won't be causing the cutting out, whereas an intermittent electrical fault could well do both.

This has all the symptoms of a dodgy earth. Check all the earths for corrosion, internal breaks (check resistance or hotspots after running). Some of the earth leads are buried and a bastard to get to - start with the easy ones. Then move onto switchgear (kill switch especially), sidestand interlock etc.

Dr Farkoffs probably hit the nail on the head, I suspect a worn load contact inside the solenoid not putting power on the starter windings.

Sorry about the bum steer regarding starter relay, I have one under the tank on my GSA and mistakenly presumed it was for the starter circuit.
 
Well ive had a productive non productive morning...

Good news is I have all the part numbers for the starter... some need professional assy / welding, the other bits are bolt on off...

I found a place that remanufactures starters, and they recognise my starter, but they have no units or parts in stock :(

no problem with the relay, its under the tooltray on the 2006

Its definatly odd,
 
Well its not the starter motor,

I found a local ish to me, firm that repairs them

I took it in, other than it looks old he cant find anything wrong..


His diagnosis is exactly what Dr F diagnosed...

bad wiring on bike... :(, or at 2nd, battery

Basically If the starter , & solenoid are getting its correct voltages & amps, it will work

So lets go earth hunting ;)
