hello everyone,

so yesterday I tried to start my bike and it was stuttering and struggling to start, the front light, neutral light etc all came on, but when holding the start button they would go extremely dim..

After trying the start button a few times it eventually gave nothing back, completely silent apart from a single click every time it’s pressed which is coming from the fuses.

Currently am charging the battery but it seems to be fully charged already and still no luck starting the bike

Try a good battery or jump leads to a good battery.
That clicking will be the heavy duty starter motor switch operated by the start push button.
Have you a digital multi-meter or do you know an electrician friend?

I have used a multi meter on the battery and it was showing the correct voltage, would you still recommend to use jump leads to a good battery?

I have also fully charged the battery now, and it changed absolutely nothing, still doing the same as before

I would try that, yes. Does the headlight dim noticeably when you squeeze the front brake (eg illuminate the brake light) or use the indicators?

Good you have a multimeter, so what is the battery reading before starting? When pressing the start button?
Also are the battery connections to the bike ok?

The bike has to be fully turned on for the front light to come on, however the indicators work just fine, the high beam works fine, flash works fine, horn etc..

Everything that I would expect not to work due to a faulty/low battery works fine.

The multimeter was used by a friend as it is his, the reading was I think 12.8 or something like that (Checked Haynes manual & it was the correct reading for the bike)

As my last question, note that the starter motor takes more current than all the other bike electrics.

I will also state that I was able to bump start the bike, so I'd personally say it's an electrical problem somewhere, would you agree?

Bump starting the bike takes little current, also as my last posts.

I would say battery is fucked, but theres an outside chance the starter motor is fucked

I was just giving my opinion but I don't know much about bikes, I don't currently have the multimeter to get the exact numbers

When I bought the bike the seller did have to charge the battery up as it wouldn't start one morning but it charged fine and then started working, but now the charger says it is fully charged but still no power from the start button

Have you bypassed the solenoid with a spanner?

The fact that the charger says it wont take any more charge doesnt mean the battery is fine.

It's possible for the battery to seem okay and then totally flake out under load.

Tried using a screwdriver and still wouldn't start

Your battery is fucked. To confirm either borrow a battery or jump it from another vehicle.

Edit: did it even turn over?

Absolutely nothing when using the screwdriver, just the same single click when pressing the start button

You wouldn't get a click if you were bypassing the solenoid

Ignition on, screwdriver between the two big terminals on the solenoid.

The click is a relay being activated. The solenoid is a relay. By bypassing it you aren't activating it.

The whole point is you are bypassing the start button.

There must have not been a click then, I did it a few hours ago so can't remember 100%, but putting the screwdriver in between the two and trying to start still did not start the bike, it did nothing

Unless I was putting the screwdriver on the wrong part mistaking it for the solenoid

Bypassing the solenoid means spinning the starter directly from the battery. You dont need to touch the start button. It should be a bit sparky.

Check the wires from the battery and the solenoid, solenoid to starter and main earth strap from the engine.

Yeah I must’ve done it wrong then as there were no sparks or anything, I’ve had a friend look and he said it’s something between the solenoid and starter, so I’m hoping it will be an easy fix once we can figure it out

Mr Nobby said he suspected an FSCK'd battery or starter. I agree. There shoul not be anything between the solenoid and starter motor, apart fron fattish wires.

If you get a length of wire and hold one end against a battery terminal, and brush the other end against the other battery terminal, there should be great big sparks as about 100A goes through the short. Don't make the short circuit continual, obviously, or your wire will glow red-hot.

If your bike won't start, and afterwards the above crude test does not produce bug fat zappy sparks, your battery is indeed a doorstop.
