Folks if anyone has a spare S10 cdi I would be interested in buying it.

If anyone has a Super Tenere and is willing to loan me their cdi for troubleshooting for a day(will replace if it gets damaged) that would be hugely appreciated.

[jamesobrady]

Quick bump. Thanks,

[Playtime]

saw a teniere in Italian Centre today (dont ask me models etc havent a clue but it was big )

Cheers Martin, Im fairly sure that one doesnt have a CDI....or a battery.....and is covered in south american dust....tsk tsk tsk

it might be nothing but I know Hugh (Northside dismantlers Santry 0860564357) broke a TDM recently there a similar motor.

Probably not interchangable, but might be worth a call

[jamesobrady]

Cheers folks, picked up one from an early model TDM today in wicklow. Should do the trick
....Now to avoid the urge to go back and get the engine and carbs and wiring loom and upgrade from 750 to 850 ......

[jamesobrady]

Bump.

Bumping this thread as the replacement Tdi has not done the trick...and now I have no way of knowing if it is good or faulty as it is second hand.

If anyone has a Super Tenere, or a 90-94 model Tdm I would really appreciate either a quick go of your tdi,or putting my tdi into your bike and see if it starts.
Many thanks.
James.

James there's a few companys in the UK that will recondition your Cdi,they will diagnose firstly if it's actually a faulty unit.Think i remember it being in and around 100 pounds plus shipping.Ive heard these lads do repairs but you'll need to contact them http://www.electrexworld.co.uk/

Cheers for that Evo, am familiar with Electrex-have a RR from them. Charge 45stg to test unit....150 to 300 to recondition. There is a company in Ukraine that make replacement Tdi for 75eur-plus 15 delivery. Am not convinced Tdi is the problem now, but no way to know without interchanging it. Pita with it at this stage.
Am thinking replacing pickup coil is the cheapest option.... trying to find one that suits without much luck-yamaha will only sell the stator and pickup together.

Well funny enough i was thinking the ignitor is probably not the problem too,i presume you've gone through the usual suspects like side stand switch,clutch switch and kill switch.Are you getting any volatge to the coils when you turn the engine over?

Edit: 12v to both sides of coil when ignition on. My understanding is the Tdi takes the "go" signal from the pickup coil and grounds one side of the coil causing it to spark.

History is that the bike was running fine until I left it in with a mechanic in Lima to get the Stator rewound(open winding), and the frame welded.
He sent the stator off to be rewound, had to remove the battery and coil to get the frame welded. He didnt disconnect the plugs from the Tdi, so left it grounded to the frame....dont get me started.

New battery bought.
All put back together and no spark.
Three days of going over all the wiring that could be gone over followed...everything checks out-all switches/cutouts ,wiring...all good.
Stator resistances are a little high, but according to the diagram, shouldnt affect ignition.

Have some sort of signal from the pickup coil, multimeter reads .4v on cranking and the resistance checks out.... dont seem to be able to do more than that without an oscilloscope.

Coil interchanged with a spare, no joy. Again, resistances check out.
Ht leads checked, plug caps...plugs...all good.

Bike back to Dublin:
Got a second hand Tdi.....installed, no change. No way to know if its a working unit.
I have an rpm sensor and crank position wheel from a cbr600, I think I can use it to imitate pickup coil and see if it makes any difference. Will try that tomorrow and see if it gives me anything. If that works I know i need a new pickup, if it doesnt, im still lost.

It might be a pickup alright but if the resistance is ok then its likely not faulty.Rather than use different pickups(which probably have different resistance values) id be setting everything back up and start with the real simple stuff again,its easy to get lost in the complication of wiring,when you get stuck the mind starts to suspect the Cdi(Tdi) because you can't see or tell whats going on in there.Im of the same thinking as you that it would be highly unlikely that 2 units are faulty and if the one you bought came from a running bike then that would really lead back to the problem being elsewhere.Have you a wiring diagram for both the Tdm and Xtz so you can make sure there are no extra wires going to one of the units or maybe even a case of having to swap one or two wires around to get the same effect.

The welding could also have fried some wiring together so you might have a short to ground on something within the starter circuit,continuity tests between the live wires on clutch,side stand and kills switch and the ground terminal on the battery will show any problems here.

I had a similar problem when i built the Hawk,the Africa Twin had a cut off for the coils and fuel pump,i suspected lots of stuff like yourself but in the end all i needed was a perminent ground from the Cdi.

Just buy all the TDM stuff and convert it....

There is an engine and carbs and wiring available....but havent the money, the space, or the time to play with it.

Checked again today, pickup resistance is bang on at 231ohms-should be between 184 and 276.

Boxes are a straight swap. No idea if second hand box is good or not as it came from a breakers. Reckon I can make a simple test rig for it, but dont have the time at the moment.

The welding could also have fried some wiring together so you might have a short to ground on something within the starter circuit,continuity tests between the live wires on clutch,side stand and kills switch and the ground terminal on the battery will show any problems here.
Quadruple checked the cutout circuit today, all good.

Not a bad idea to put a permanent ground on it for troubleshooting. Will do that as soon as I get the bike to a place where I can put some time into it.

As an info aside:
Bought a new TDI from http://www.ignitech.cz/
Tis programmable for spark advance/retard and all Ted.
Very impressed with service from them, arrived in 3 days via DHL.

They do TDI's for all bikes that need one. If it isnt listed, supply them the details and they will come up with a solution.
Not sure if they can provide for more modern FI bikes that use 3D type fuel mapping....but anything carbed and you're laughing.

[jamesobrady]

Had a play with the bike today while finishing off a six pack of miller after work.
New box of magic made no difference so I pulled off the alternator cover and found this :


That is a pinched signal wire from the pick-up coil that gives the tdi the signal that the crank is in a certain position.
Amazingly, the resistance of the coil still reads perfectly with the wire like that, but I will take a guess that the signal from the pick-up isnt good
Will replace it tomorrow and see what happens.

Smokey lives again.

Not shown on that picture is the gasket that I removed. The wire was insulated on one side by the plastic insulation that is crushed, and by the gasket on the other side...hence no grounding. There is maybe one or two strands of wire left intact letting a multimeter get a resistance check on the coil, but not letting the pickup signal fire the box.
