Honda NSR startin issue - CDI?

[christhedude]

Looking for some help with my baby!

Please view this video as it will save us all time, gives a run-down of the bike so far.

https://www.youtube.com/watch?v=f4vIvfOZ9PE

Mentioned in vid, Vehicle ID / chassis number is:

ZDCJ22800F blah blah.

No spark at all.

Replaced:
Spark plug
Ht cap + coil
Starter Motor

Suspects:
CDI
Reg ?

Potential remedy:
New CDI
Alternator (although we checked it and it seems fine.)

Please help a brother out

regards

Chris

Have you tested the stator for its output levels? Same with the coil? Have you checked the starter relay? The battery earth?

If you need any parts ive got a running bike that im breaking so please dont go forking out daft prices for parts to eliminate problems that arent really there. £120 for a starter motor is rediculous lol.

[christhedude]

Yeah 120 cos i had to import from bloody ireland. None anywhere in the uk, scoured sites for them!

Well we ain't got an ohmeter atm, Main lights n stuff work so don't think it's the battery.

What's the starter relay? Where is it located and what can i do to check it works?

If you got a CDI you wanna flog i may be able to scrape funds together for it.
Almost certain it's that considering the rest of it.

[Mikey CB500]

That sucks, I would have sold you one at half the price. And the starter relay is the part that the positive battery goes too.

And its not the battery mate no, but a grounding problem would only be notified by there being no spark, the other electrics will work still.

[christhedude]

Tomorrow i'll go over all the wiring from the battery onwards (as seen in video, not enough light in the garage!) and find what it leads to, there may be an issue on the wires.
Is there a 15A fuse somewhere that may have blown? Or is that the one that i pointed out under the seat?

How much you want for the CDI on your NSR? What model is the CDI?

[Mikey CB500]

[christhedude]

Didn't even see the message, watching Biker Vlogs on youtube

Right so to confirm, plan of action is to check the earth from the battery to the starter relay tomorrow when there's light. If that fails, grab a CDI and attempt again!

[Mikey CB500]

No the earth goes from the battery to a point on the frame, or it should do.

Should be the possitive battery lead goes to the starter relay.

[christhedude]

Ok got some pics which may help if you can point out where this earth should be, only got stuff coming off the positive and negative - none of which seem to go to the frame for earthing!

That thick dark green wire that goes from the battery to the loom, trace it and you should find it bolts to the plate on the frame where the rectifier attaches

Make sure that the plate and the part bolting to it are shinny and clean making a good clean conection.

[christhedude]

Not sure if this is correct, however the only cable that i can find that is connecting to the frame was beneath the left side of the rear fairing. It does not (at a glance) connect to the frame with any metal contact though.

Also, i saw these 2 small 2-pin and 3-pin nodes that stick out of the loom. Are they likely to be of any relevance?

https://i1222.photobucket.com/albums/dd487/christhedude/whatarethese.jpg

They seem to be fine however, as i mentioned before, I'm no bike surgeon

Would like to take this opportunity to really thank you for the help you have offered too. I love this website for the friendly and "happy-to-help" people you get on here

[Mikey CB500]

Let me double check on mine tommorow but im sure its behind the rhs seat fairing next to the rectifier.

Been a few years since i had my old nsr on the road haha.

[christhedude]

Do we have any other potential ideas folks?

[alains]

your video & picts are bull shit and it's very hard to catch what you said . the process to check your ignition is simple
and you should forget about a faulty CDI (they burn very rarely)
download my file https://www.geneva-racing.ch/~alains/NSRtips.doc
then do this :
- lift tank on its stick
- take off plug and put a new one (BR9EIX) with the cap on
- let it laying on the cylinder head (plug metal must be in contact with the head)
- push your start button for 3 to 5 s while observing the plug
- if you see a nice blue spark , your problem is in fuel line
if no sparks :
- set your multimeter in Ohmmeter 0-300 Ohms and look my file at page #11 about checking stator & impulse coil
- if it seems OK now set your multimeter on 200 VAC and do not put the plug
- connect multimeter between red/black and any ground (stator connector) then push start button for 5 s , you must read at least 70 VAC , otherwise the stator is out of order
if everything is right , now you can think about the CDI
my experiency shows 15 dead stators against 1 CDI

Thanks for the response (video isn't great i know...)

Already replaced spark plug with BR9EIX from readin the forums beforehand. I read your file already.

There is no spark still even after replacing the coil etc etc.

My father agrees that it is more likely the Stator, and we've ordered in both just in case.

Thanks for the help and the files Alains, would have been bloody lost without them.

[christhedude]

Ok so I am officially lost now.

Replaced the Stator, coil and spark plug (with a new starter motor cos the old one was shot!).

Got a CDI coming soon, thinking it's a bad earth somewhere in the wiring loom but it's been all taped off together OR it could be the killswitch is broken and permanently off cuttin the spark.

Anyone wanna buy an NSR? lol

[bikenut]

:karma: hi dude dont know bike but cdi has black wire with white trace?? if so disconnect from cdi ( so rest of bike is disconnected from ign system ) and try for sparks. still no sparks then its not the bikes ign kill circuits.

if sparks then bikes ign kill circuit has problem ( earthing when it shouldnt ) the black/white wire is ign kill but check on wiring diagram, earth to kill ign.

[christhedude]

Be prepared for this cos it is really, really fuckin stupid.

What i thought was my CDI has tv-78 written on it. Now i know that c1639 or c1626 should be on there somewhere! xD

Where exactly should my CDI be situated? I can't find any other small black boxes of the same kind (Carb is on atm, don't want to mess with it).

[cb1rocket]

There should be a pulse pick up sensor at one end of the crank. Check this. There is a reading in ohm for this using a multimeter, check with Alains/workshop manual

Usually they give a good reading but are intermittent and don't show up as faulty, change that and see.

What happened to me that turned out to be that part for the last 9 months trying to fix!

[christhedude]

You mean the pickup on the alternator/Stator? (whatever you wanna call it.)

Replaced that but it could well be a shit replacement (that's the problem with replacement parts from bike breakers!)

[cb1rocket]

yes that the part, could well be faulty, they are near impossible to check unless you have an oscillator!

[alains]

it's called impluse coil , it provides a 5-10 mA to unlock the thyristor (triac) of the CDI
