SV650 will not start after long run....

I had noticed my SV650 was running low on oil. I continued my early morning 20 mile commute, promising that I would top it up when I returned that evening.

The next morning I topped it up with some oil (which I later found out was 20/50 and not the recomeded 10/40)
I tried to start, and nothing. The igniton lights came on, neutral light on, and side stand down (in park position). The odd thing was that I now noticed the red oil light was lit.

My first thought was I had overfilled the oil, as the viewing window was not 100% accurate. So I drained some oil to the min level.

Bugger will still not turn over. Everything else on the bike works normal, eg Lights, Indicators, Horn. I even checked all the fuses, and they were all ok too. The battery is charged, and in good condition.

I have read a service sheet, and ask to check Motor kill switch, and starter relay.

Thing is I cannot find the starter relay after removing, side panels, both seats, and lifting the petrol tank.

I know its located on the RHS of the bike somewhere.

Any ideas appreciated

Is the some kind of oil level detector on the SV?
Will it still turn over with little or no oil in the sump?
Where or what does the starter relay look like, wat size is it?
Is the oil type critical?

Thanks for your answers

Putting a small amount of thicker oil in wont do much harm (20/50 is thick though!), how much did you put in? Does it move whilst in gear? Have you tried bumping it?
Also some bikes have a safety switch on the clutch....not sure if the sv has one.

Will it start with side stand up ?

20/50 wont make any diffrence to it starting.

Does it make any clicking noises when pressing the starter ?

if youve just turned on the ignition and not started the bike then shouldnt the red oil light be on and goes out when you start it?

as said 20/50 is real think and there may be a possibility that your starter just cant do it.

worse thing i am seeing is that you rode it a long while low and have caused piston damage possible seize? it would keep going while hot but now its been turned off its seized.

put it in gear and see if you can push it forward a little if not.. sorry.

If the starter was trying to turn over but couldn't, surely you'd get a little peep out of it though?

Don't you get a click or anything?

Okay firstly Chris don't panic, your non-starting has NOTHING to do with the type of oil you've used.

Might be stating the obvious but your battery isn't just flat perchance?

If it's flat enough you won't get even a click from the relay, but you might still get dashboard lights.

Thanks for the many many replies all.
Well it turns out after stripping all the seat panel, side panels, Half a front faring, Petrol tank, and removing half the outer PVC tape from the wiring loom by the starter relay ...... I finally managed to locae the fault.

A FAULTY CLUTCH POSITION SWITCH !

Took me at least 4-5hours to find it. I have now topped up the oil with the correct type 10/40 as there was hardly in the viewing window when the bike was upright.

I usually propp the bike up centrally using two (car type) axle stands either side of the rear swing arm. Does the trick nicely, no need for fancy Paddock stands hey!

Anyway, one to look out for in future hey. I just pulled the connector off the clutch switch, then shorted the two terminals using a short link wire, and hey, it turned over just like it shud.

Funny thing, was I was convinced it was something to do with the imobiliser. Anyway, after stripping half the wiring loom (looking for colour coding and test points) I did discover where the imobiser breaks the starter relay circuit. So I would know where to start, next time when tracing wiring / starter problem should it ever happen again (touch wood) hopefully not.

Anyway people. Many thanks again for all of your input.

Chris
Very Happy

Annoying that they can't put a couple of shitty LED's on the ECU that light up to indicate things like this, eh?

Electrical problems, what an absolute nightmare.

Had an intermittently faulty front brake switch on my SV which consumed more hours than a marriage, and for such a stupid thing.
