If you pay attention to which of the two circuits of the solenoid that YouTubeer is testing for resistance, this battery pack is not supplying voltage to the circuit being tested for resistance.with the ohm meter.

GSX 250 starter solenoid issue
- Thread starter ukjules
- Start date
" After 5 min. of bridging solenoid posts". I'm not sure what you're say'in. What happened when you first bridged the posts? did the starter start turning the eng.? Did you leave them bridged for continues 5 min. and nothing happened, starter not turning eng.? If you bridged the posts (for sure 12V to starter) & nothing happened, problem got to be at starter, got to be bad pos. connection at starter, bad ground at starter, or bad starter. Starter grounds through mounting bolts, remove starter cover & be sure the mounting bolts are tight, check for tight connection on Pos. cable.

Let's forget this !
Reading from an individual on here that I should pay attention has done it for me.
No he should pay attention and not ever comment such rubbish on my posts again.
Please don't comment again on my posts.
The way is clear ! as UK nut informs !
Consider this post closed.
I won't bother doing detailed analysis on this site again to help others.

Dang, no need to get stirred up, he didn't just say "PAY ATTENTION", he's just say'in be sure you're pay'in attention to which circuit of the solenoid you are checking, as the 2 different circuits are checked different ways & have completely different readings. Please don't get aggravated with me, but all your tests, as well as the U-Tube guys tests, got me a little confused... I'm way simpler, If you check the voltage on the outlet side of the solenoid while key on and starter button pushed, if you get 12V, the solenoid has done its job, put 12V to the starter, that's all the solenoid ever does. But in your case, sometimes it works & sometimes it don't, you'll need to keep trying it over & over till you see the voltage at the outlet lug both when it cranks and when it don't crank. If you push the button &the lug "gets 12V" but starter doesn't turn eng., the problem got to be Pos. connection at starter, ground at starter, or starter itself. If when pushing the button, starter doesn't turn eng. & you're getting 0V at outlet lug, way most likely a bad solenoid, could be wiring feeding 12V to solenoid, but that would be much rarer.... Be sure, we're just trying to help get your GS up & as reliable as we can.... Good luck.
Just for future reference I just tested resistance in my 44 year old solenoid.
With the solenoid completely disconnected and laying on the bench, I read 3.5 ohms across the control circuit.
With voltage applied across the control circuit to activate the solenoid, I read 0.1 ohms across the big lugs.
Hope that helps.

I am gonna continue this thread as so interesting. The question is at the end.
GSX no start issue which came on suddenly and now strains to turn the starter motor 99% of the time -just clicks but may work 1% of the time.
Solenoid seemed fine , bought another and same result.
Anyway had to be down to the starter motor as if energise motor direct in bike it gives exactly the same results.
Removed starter motor and spins every time no probs at all on bench. Clearly must be brushes or dirt.
Dismantled the motor and noticed one of the magnets that is glued to the inside wall of the body was off !! . stuck to the rotor by magnetism and consequently spreading dust whenever the ignition pressed.
So cleaned up (pics attached ) tested commutator and all is fine (ohm tests).
I will clean commutator with 400 wet and dry.
Now these starters are hard to get ! I have a second hand one coming as they are not available now. Had to get one to protect bike.
I desire to fix the original that needs:
- the inner magnet glued back with loctite 325 that Is recommended for motor magnets ? Note in the pic there are raised notches that keep it in correct position one way and I can measure gap for other way. So can be sure in correct location .
and
- know how to replace the brushes ?
pic attached and I can't see how to take out one of the brushes ? one easy one seems impossible.
Q) Do all agree that glueing back with said loctite 325 is the only way open to me.
Q) In pic how on earth do you get one of the brushes out ?
note - brushes both at 10.1mm and ok till 9mm service manual informs so I ask not needing to do if I can't find out . I just can't see a way

Rotor and commutator. This tests fine on all Ohm tests. Will clean commutator with 400 paper.
Note this was black when I opened up the motor.
so 2 questions. what glue and how get the brushes out ?
and has anyone else had luck glueing up their starter motor ?

Be useful to know if loctite 326 can be used without an activator ? (I don't have the activator).
Be useful to know others experience.
I intend to apply without and wait for as many days it takes to fully cure. I don't think it has lesser properties using without the activator.

Update:
Glue arrives tomorrow. Worst case scenario is to a
local motor electrical place here to sort. Seems
this sort of thing is well known to these people.
what amazes me is that this exact starter motor is unavailable now. not even a replacement made for the GSX 250 is available. A few for sale for.mad prices in Europe and that's it.
But I will glue it as there is zero doubt that Loctite 326 is the right glue. so I will see how it lasts me doing it.

I don't think it will do much without the activator.
If you don't have the activator, why not just use an epoxy two-pack?
I'm like him ^^^^ wouldn't attempt without activator. And would really hate using anything till I knew it would work. You said you have a local motor & electrical place, Why not ask them what works good? I've usually had pretty good luck by asking questions.

Ok disaster !
Glue arrived in small tube. consistency of mixed areldite. pasted on back of magnet , stuck in magnet - all good.
No activator.
BUT
Remember the magnet was damaged and I could see it was not fitting correctly as worn. I hoped anyway.
ANYWAY
I left it for 4 hours and I just had to know if the rotor would go through with this possibly mishaped magnet.
It didn't. It stuck on one end.
- either I put too much glue on the back making rotor jam last few cm's
- magnet was so deformed it never was gonna work
- I had it a millimetre to far in and raised on one of the pins.
All possible but it didn't work (read on). Probably never was gonna anyway.
So out with the magnet :
The glue in just 4 hours was so strong I have had to use a hammer and screw driver to get it out. Even that is not good enough and I will have to use a Dremel probably to get It all out.
The strongest glue I have ever known !!!!!!
So the glue is as strong as you can get for sure !
I cleaned area with brake cleaner beforehand only.
- I will take unit to an electrical place now and ask can you get magnets for this and fit together.
if not I need to get another starter motor which are not about. not for human being sort of prices .

p.s I researched that this glue is the right stuff and very strong !!! It says nothing about using an activator on the packet either !
Whatever I now know it doesn't need it !
(gonna fix my broken Murano glass vase from Venice with it now) areldite has never held it !
So it's bump start bike with a good battery I suppose .
I was gonna start a thread of ' how to add a kick starter to a gsx250' but assume that would be the final straw for the moderators .....

Have sent 10's of emails (with full spec and size) around the world and I have one response who will ask their suppliers where a very similar starter motor is made to see what can be done about this starter that has dropped out of the market.
A can do person who will contact the manufacturer of the almost right Suzuki replacement and then the makers. I have no doubt I am talking to China now for this part.
I am convinced there can not be a massive variation of circumference of Japanese starters and hence at the very least magnets that can be sourced .
