Hi all.. Newby here... HEEEELLLPPPP

[Wolfie]

It is a new battery, 12.6v ish
The bike turns over fine just no life in the way of firing
I'm taking my stator and rec/reg into work tomorrow see if the maintainance dept can discover any problems.
if the stator is toast then i'll get one of them (and probably another rec/reg)

Plugs sparking?, plugs wet?

 

[Wolfie]

I realise Wolfie probably means well, he just caught me at a bit of a low ebb, and very un-melike I responded.. lol:xm

Damn you wolfie!!!

Nope, I am a coont, a bully and ex lover of Lumpy, also having anger management sessions as I like to break things for some reason

not got that far yet wolfie.

couldn't find my long reach plug spanner

thats a job for tomorrow as is the ignition wiring

call me old fashioned but just reading the resistance of the stator windings is not a proper test as they could be breaking down under load (charging the battery). Testing them to earth with a megger insulation tester is a better test. Also the battery cannot be properly tested unless under load, so a 12v reading with no load applied does NOT indicate a good battery, I have a caravan battery in my garage which will happily read 12v on a voltmeter until you put a resistance across it, at which point it drops to about 5, because it is Knackered! I use a 25watt resistor at about 2 ohms (ohms law I = V/R therefore 12/2 = 6amp load and therefore a suitable test for a bike battery. keep your hands off the resistor though it will get warm....

so, to recap, and since I've been a member here, in a nutshell, bird problems is order of likelihood :

Got a carb bird with an issue? = it'll be the reg/rec 99% of the time

Got an Efi bird with an issue? = it'll be the loom fix 99% of the time

Got a noisy engine? (carb or Efi) it's the CCT 99% of the time

Got a funny wobble at the front (either model) then it's that top box or rack you fitted 99% of the time.

any other faults on either model, the other 1%.

This post, just this one could do with being a sticky 8rfl@8rfl@ Spot on.

Err...check the breather pipe on the petrol tank. My old 600 died on me when I got it pinched after pulling the tank off and back on. Could do a good few miles and she'd just die, open the cap, whoosh of air and off again for another few miles??
Rerouted the pipe and all was well.

Stator test, nothing between any of the yellow wires and earth. Between each yellow wire 0.1 to 1 ohm any different it is toast.

There is no spark & whatever the intermittent fault was, it now seems much more permanent..

I've had advice today from a bike shop as to how to disable the immobiliser, tried that so either its not that or i've done it wrong..

Tested the stator on a megger insulation tester. all seems fine all 0.4 ohm between yellow wires, nowt between wires and earth.

Stay positive on this (no pun intended) - if there is no spark but the bike is turning over I think you will have narrowed it down quite a lot. I am not convinced of alarm/immobiliser problem as surely it wouldn't even turn over?

If there is no spark logic says to start at the spark plugs (which are presumably clean) and work back. Which takes us to the HT leads and coils. On th basis there are more than one of both these presumably at least you would get spark/firing on one or more cylinder??

Come on guys, this needs sorting so apply your greater wisdom than mine........ working back what is next after coils??

Just out of interest, have you tried firing Cold Start into the air intake while trying to start it - I know you said 'no spark' but it is a really simple way of being 100%certain that there isn't a spark as it will fire briefly and then die. If this happens you do have a spark but almost certainly no fuel.

 

[PeterT118]

Yes tried cold start tonight.. not a sausage..

Only took one spark plug out, but like you say it would only take one to spark to make it at least cough and splutter a bit.

Often immobilisers still let the starter motor turn over..

I have my bro-in-law who is a bike mechanic coming round at the weekend to see what he can find..

this may help

Dunno what shop you went to but if they told you it is possible to check a stator with an ohm meter to say they are giving misleading info is an understatement ( unless you are an electronics engineer and have access to a stabilised regulated PSU and reasonable quality oscilloscope that is )

Even an AVO 8 struggles to measure anything under an Ohm with any accuracy and modern digital meters are as much use as bumholes

Andddddd .. The stator has absolutely nowt to do with the bike running.. You could take it out and throw it away and the bike will still run fine ( until the battery goes flat )

Would it be possible for you to ring me ?
Any time, 9am to 10 pm daily ( 01842 754415 or 0781 8822887 ) as I may be able to help a bit better 'live' rather than back and forth on here @tu*

 

[PeterT118]

It was somebody on here who put the possible Stator reading.

I will try to ring you tomorrow when I finish work at dinner

@tu*

 

[PeterT118]

HALLELUJAH !!!!!!!

:bow:JAWS You are the Man!!!!!!!!:bow:
​

Jaws managed to sprinkle his magic dust down the phone line...

It was the immobiliser, water had got into the loom on the left hand side and knackered up the alarm wiring!!!

The voltage across all 3 of the stator wires is within .5v of each other, so hopefully ok!!

Just waiting for a new rec/reg unit to turn up (the one I had ordered didn't match up with the bolt holes..


then I will tentatively and carefully take her out for a test (not wanting to upset Wolfie, lol ;-0)))

@tu*Thanks for all your help everybody @tu*

congratulations also for reaching 50 posts in almost the only fucking thread you've been in :-0)

Haha.. I know... I hope from now on I can be a more useful member of the site..

Maybe giving advice for a change... 8rfl@

 

[PeterT118]

HaHa..8rfl@:-0)

 

[Wolfie]

first bit of advice could be to tell Wolfie to go fuck himself

Was you allowed to type that post out yourself, or did you do it in secret Pottymouth?

 

[bmwdumptruck]

Mind you, I did wonder how Wolfie thinks most half decent mechanics prove they've cured faults on bikes and cars without a test ride?? h1d1ng2

Half decent mechanic would of known that a reg rec was not the problem and the ones I know would of had it running in the workshop to check all was fine before they took it out,

 

[4_4_2]

Does it have an alarm system fitted??

post six........... problem identified? mmmmmm good spot!
