HELP :( ! NSR125 wiring problem

sgc1000000 · Derestricted Danger Joined: 01 Dec 2010 Karma :

Hi there,

I am new to these forums so may I take this opportunity to say HI!

I recently purchased an NSR125 on ebay and everything was good however the agreement with the seller was that it needs a new ignition barrel. I personally don't know the first thing about bikes at the moment but am very mechanically minded.

When I turn the key to 'on' I get no power what so ever nothing happens at all and no switches do anything (it is a different key to the filler cap which does feel suspicious)

apparently it does bump start but I cant try it on my road with all these obstacles and cars, also the clutch is dragging from the cold.

What can I do to get her working again and ride her once more.

Also I took the seat off the other day to find 2 wires with circular ends which looked like they should connect to the battery terminals I tried connecting them up but no lick.

Cheers
Sam

Although it is suspicious, there may be a logical explanation. My bike has a different ignition key because i left my keys in the ignition, and some annoying kids stole them, so i needed a new ignition barrel

You can get a cheapo ignition from ebay

here

They're not too hard to fit. But i suggest you do some standard checks on the rest of the ignition system before you fork out.

Thanks , It is a 1998 RR model but I have found an ignition barrel however What other checks should I carry out and how would I go about it, also how do I fit the new barrel?

You said nothing works at all when you turn the ignition on - in that case no electricity is either getting past or to the barrel.

With electricity its always good to start testing systems as whole to eliminate the issue.

The seller said it bump started - yet when you turn the key nothing happens. If it can be bump started that implies the ignition barrel should work, if it didn't - it wouldn't bump start unless the whole thing has been bogged.

I know it's obvious - but have you checked the battery? If you don't have a multimeter, a 12V bulb and a bit or wiring held over the battery terminals will show whether there is any juice in the battery.

If the battery checks out fine I would suggest you take off the old barrel, and make 'bridges' across the terminals to find out if the electricity gets past with the bridge in place.

But check the battery first, and see what that says.

Thanks, I dont have access to a multi meter at the moment but the previous owner said he can bump start it but needs a new ignition barrel wiring loom as he had to do a 'quick Job' wiring it up

As for terminals behind the barrel im not so sure where they are or how I even get the barrel out

Hey,
If you havnt already paied for the bike i would reccomend walking away...
The NSR's can be an absoloute ball ach when it comes to electrics and if he is saying a new wiring loom it would certainly make me think very hard...
Wiring loom is only about £30 on e-bay, a barrel/tank/lock set would be around £50 if yr bothered about only needing one key.

There is a chance the bike will run without a battery connected (my old 4t would) but i am yet to try it with the NSR. All the terminals (round thingys under the seat near the battery) need to be connected to complete the circut and for things to work properlly.

Again, how much are you paying for this? It could prove to be a fair bit of work Neutral

What kind of condition is it in cosmetically/mechanically?

If it's the red one still on Ebay (auction ended 17.11) then this about says it all:

Comment from seller:

" i had to do a Quick job wiring it out now meaning that the battery will not charge"

Your battery will probably be dead, and this quick job will need fixing. You can tackle this yourself, but i'd suggest finding someone who knows a thing or two about electrics. It's going to be quite hard to give advice without seeing whats happened.

But if you want to try, step one is to find an remove the "fix" and return the wiring to their proper routes - and then remove the barrel and test it.

I cannot tell you for sure how, but usually the barrel is attached to the top yolk or the clock mounts. It's usually bolted down somewhere in that region, so a good look around might prove useful.

Yes it is the red one on ebay (https://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=110610130765&ssPageName=STRK:MEWNX:IT)

I have bought and it is with me now,

Could anyone provide a video of how to remove the ignition barrel at all?

and I can work out how to remove the battery but im not sure how to wire in these two spare wires that have been left loose under the seat

Thanks
Sam

Heres a rough guide as to what you need to do to get the ignition barrell off. Technically, the barrell should be a quick switchover, however it does look like there may be something else involved, especially if you can bumpstart it.

Take off your fairings. Its not 100% vital to do this, but it helps to be able to get at the barrell from different angles. It'll make so much easier if you take 5 minutes to unscrew some bolts and take off the fairings

Put your tools down, look at the bloody thing, find where the cabling is leading to. take note of the way it is wired, and the way that each connector fits, write it down if you have to. This will be your chance to expect the rest of the wiring too, seeing as you have the fairing off.

Now, generally speaking, the ignition barrel will be held in by the top yoke, so you'll have to take that off. This means removing it off of your forks.

unscrew anything fastening the barrel and holding it in place. Once again, take note of how it fits. Now switch it with the new one. make sure you have it the right way round!

Clip the barrell into the wiring, and test it. if it starts, then put everything back together!

If it doesn't start, then get a meter and check the system. Start with the whole system, and make sure the circuit isn't broken, If it is, then start narrowing down the amount of circuit that you're testing until you isolate the problem.

As said above, there could be a whole host of issues. The bike does seem dodgy, not to put you off. but do be prepared to find that it isn't the ignition at fault.

To be perfectly honest, i'd do the meter checking before i buy a barrel or take shit apart. it'll save you hassle if you know that the barrel is definitely the solution to the problem

Thanks for the reply,

I am currently thinking I will get a bike shop to isolate the problem because even if I do get a mete I would not know what to look for anyway however at £50 an hour I can only afford for them to tell me the problem and not to fix it,

A few other questions that may seam very basic but if I dont ask I will not know (it also helps novices who read this) but whats a yoke? and does 'wiring loom' refer to all the wiring on the bike?

Thanks
Sam

all answers=bull shit
first of all check your fuse (near the battery +) and clean the clips (#400 waterproof sand paper)
if nothing happens check the terminals under the key , it's only a loose contact somewhere
bumpstart is ok because ignition has no relation with the battery ( it's an AC-CDI working at about 200 VAC)

Thanks, I checked the fuse is ok and clips for it are clean, will it bump even if the battery is dead?

looking at that i would just replace the loom, someones had some serious fun in there and your problem could stem from any one of those bodge jobs.

You could test and check all the wires but in my experience, once you start to tamper with a loom the problems snowball and spread like cancer so for the sake of £30 it's well worth replacing the lot.

ok so if I buy a new loom (i take it you mean all the wiring for the complete bike) I still need to know which ignition barrel I need, can anyone help by the photo's

The bike is a 1998 foxeye NSR125RR (i think)

Thanks

I near passed out when I seen that wiring..... effin' ell.

Anyhoo... my 2 pence worth here.... if you want to get your bike running leave it outside your house for a few nights.... some little turd would probably show you how to start it within a few seconds... only problem would be stopping them again.

Not that I know anything on the subject or anything.... but if the ignition barrel has been snapped off then there should be a little slot that you can fit a flat headed screwdriver in allowing you to switch the ignition lights on (if they are the same as cars anyway).

If not then you can bridge the terminals at the back of the ignition barrel to get ignition lights (don't forget to disconnect when you switch it off).
Start to finish should take about 8 seconds to try one then the other...

salty21 · World Chat Champion Joined: 08 Jun 2006 Karma :

chances are, that wiring is at fault and not the barrel itself (unless the barrel is destroyed) so you may as well get the loom swapped for a decent one and go from there as that may be all you need to do.

ok so how do I go about getting a new loom? and are there any NEW ones around still?

also should I get a charge for the battery so that I know its charged?

Thanks
Sam

skatefreak · World Chat Champion Joined: 06 Feb 2010 Karma :

Yep,
Sadly due to the age and the fact they are honda you will find that if you go to a honda dealer they will ask for £130 for a new loom...

Or, £30 bucks online for one in fair condition...

Ebay wins here i guess....

ok thats fine but how to I know if the loom and ignition barrel are compatible is what i am getting at

DANNYBOI · Two Stroke Sniffer Joined: 06 May 2010 Karma :

WHOOOOOOOOOOOOOOOOOOOOOOO wait a minute no one has asked the obvious question here the bike will not start will not bump ect look at picture 8 looks like an alarm and looks like those wires are spliced into it if it has an alarm that would explain a lot but holy fuck that wireing is dogy!!
