nsr electric problems again...

[Leviathan]

right, here on the workshop forum again, this time its bad, i was going along and it started backfiring and cut out, pulled over to find a connector had come loose by the cdi, pushed it together and it worked for another couple of miles, then it conked out again, pushed the connector together again but this time it isnt starting, just turns over and over i checked for spark, no spark, got home and wired the wires into a new connector...no spark...have i mashed my coil or cdi? any ideas? cheers.

also looks like the connector was home made, pervious owner loved DIY, shame he didnt like doing it properly...any help? thanks in advance.

[biker_king]

what modale is it? sounds like someone has had a go at derestricting it i would go throw the ignition system and replace any dodgy connecters ect.

[Leviathan]

i think its the UK model, an 02 Foxeye, its got jc22 written on the frame number, but other than that im clueles, i thought the UK models didnt have restrictions on the ignition or electrics, but from the looks of this guys handy work maybe he didnt have a clue what he was doing? lol

Funnily enough this has just happened to mine AGAIN, and the last time is was the coil, haven't had a look today as by the time I got recovered AGAIN and got my wet gear off ( three day bike rally ) I couldn't be arsed but when I have a look in the week I'm expecting it to be the coil again, theye are only around a tenner but a bit of a bitch to change if you've got big hands...

cheers guys, im going with coil for now, if thats what it is ill certainly let you know, thanks for your help

[Leviathan]

right gents, heres the low down...


...checked the connections, everything seems ok, but im no expert so it could still be earthing somewhere(hope to god it isnt), now some of the loom is wraped in green tape? please tell me this is stock, or im in real dodo, cause it looks like a fellow has been at it with a hacksaw, if im wrong ok, i just think that the green tape at certain points is a bit weird, maybe like its been tampered with and really dont wanna be tearing that apart looking for faults, but lets say for a second the loom is fine, i put another coil on, it was all together and turned it over, no spark... any ideas if any key connectors have gone? the cdi connector is now insulated, and the connectors down the left rear panel are all connected right too,
i did however wire in a new earth, with the flat ring shape head, cannot remember the real name of it, its the one the bolt goes through to fix the earth, anyway thats insulated but could that be earthing? can an earth earth? lol, bearing in mind someone had already crimped another wire for some reason that connects to the coil itself,

any help would be really really appreciated,

cheers,
Gary.

check with great attention the black/yellow wire coming from the CDI (on the 4 wires connector) , going to the coil primary and tachometer . most of bugs comes from oxyded or loose terminals
if your loom is not in good shape i've got one here from a 2001 UK bike , if you want it £25 including postage from france

aww alains your a saint, ill check the wiring tomoro, and that wire was looking in bad shape too, ill see if i can somehow solder a new connection and insulated it with some rubber and electrical tape while i check every wire too and from the cdi, clean the connectors and check the pins and receivers too, cheers for your help guys ill let you know my findings tomoro,

there shouldnt be any green tape lol. my bike had had some seriously dodgy diy jobs done when i got it, i just started replacing all bodged bits 1 by 1 in july 2006 and am still goin, i bet i could build another bike with all the spares i have i even have a spare engine and 4 cylinders dont ask lol

lol, aw man were probably in the same boat, im going to see if i can get a volt meter on the coil and cdi and test for resistance, and if everything seems ok im going to ask alains nicely if i can buy that one off him, im loosing my mind with this the green tape is in a few locations, like he tried to wire in a new ignition system but the cdi and coil look stock, anyway, ill report what i find, i wish there was a way to test current the wires in the connector blocks that would realli narrow it down, can it be done? anyone know how? cheers for all your help im getting there! lol

[Leviathan]

ok, checked the loom, theres alot of bodged jobs on it, i cant understand why someone would mess a perfectly good loom, so my only suggestion is that it is an import, i was pretty sure it wasnt for some reason, but im going to check on the frame number in a min, i swear i saw a C but maybe not in the right place, and also i repaired alot of the wiring and everything seems to be connected up properly, but still nothing, it all turns over fine and i get lights and everything but just no spark, and i did try with a different coil, but could i have blown anything else except cdi? iv found (what i think is the signal unit) that looks ok but a bit worn, anyone have any experience with that?

anyway cheers for everything guys keep posting please lol

ok, just had a look at the frame properly and it seems to be an italian import, does that warrent for the hacking of the ignition loom, when the bike worked it did over 90mph, and any idea how to troubleshoot a homemade system lol? cheers in advance


Gary.

[alains]

italian import serial begin by ZDCJC22A , UK by ZDCJC22C and they have the same specs . a well tuned IT or UK reach easily 100 Mph likle mine which is french but rebuid under UK specs
your CDI must be marked CI626 (not CI626A) and your RC/valves control unit TV78 .

yes alains you are completley correct

im still stuck then as to why this wiring loom has been fiddled with, but am going to try a new coil when it arrives either tommorow or the day after, upon failing that i shall indeed purchase that wiring loom from you, thank you for everything everybody, i shall let you know how it goes,


Gary.

[Leviathan]

alright gents, all fixed. I went through the loom and fixed up all the crappy connections and broken wires, now it starts no problem, and even revs better than before, hope im not in the workshop any time soon! but cheers for all your help people, much apreciated
