well, after reading all the threads about fitting 600 coil sticks in place of the gills it seems that most threads ended inconclusively except one or two on the tigers so i thought what the hell, its winter and the bike is in the garage so i have ordered a set off ebay to try for myself, cost 45bucks for four so i am not out much if it fails! ordered some plug ends too so should be waterproofed as oem, will let you all know what happens when i fit them, if anyone has info regarding any issues to look for then please shout up!

i got some time this morning so decided to get into a trial fit and temporarily wire the coils in to see if it would fire or not! the middle stick is a b@#$h to get in but it will go from lefthand side with a bit of lube on the lower part of the boot, i used some .110 spades to fit on the sticks until the correct plugs arrive from ebay, note, if you are looking directly at the pins the positive is on the right, it might not matter but thought i would put it out there, well, it fired right up from cold and unlike before i could turn choke off almost immediately and it never stalled, i cant ride it as our roads are white!! tach works as before and as a bonus you will be removing over 3lb of weight from the gills and plugwires too! coils were $45 for four used and correct plugs for wiring $10 off ebay, the plugs are the same for all denso 2 pin coilsticks, 4.6 fords use them, mine were cbr600 items, so hopefully when snow is gone i can have a ride to see if all remains good but this seems a very cheap upgrade and with black braided wire loom you will be hard pressed to even tell they are not stock,

With an electronic ignition you might not notice a difference, but electrons jump more easily from a hot surface to a (relatively) cold surface. In the spark plug world, this is from the center electrode to the side electrode. Reversing the polarity can result in a 15 to 30% increase in voltage required to fire the plug.

The polarity of the high tension system is independent of the vehicle polarity. Electron flow is opposite what we call conventional current (positive to negative) so the center electrode of the spark plug is actually negative relative to the side electrode and cylinder head.

On older coil and points ignitions it could make a significant difference; the result was generally a high speed miss-fire.

That's cool that they work. I just hope that the resistance is right so you don't cook your igniter.

how far out do you think it could go before being an issue? i know there are tiger owners that have put thousands of miles on these with no issues but i am no electrical guy! on another forum (benelli) a guy measured the earlier tt600 sticks at 0.950-1.000 mohn primary and 11.1kohm secondary, versus triumph gill at 0.63mohm and 10.5kohm, i dont know if this differs enough to cause issues or not, he also said later daytona 675 were higher numbers and not to use, if any electrical gurus can chime in i am all ears!

The Nology coils are 0.6 Ohlm coils.
I thought there was something about how they load and fire that predicated the 0.6 ohlms. IrlMike is the ignition guy around here....

Someone called? ;)

I don't have a TT600 manual & haven't done part # cross references, but the stick/plugtop coils on the 1st Gen & 2nd Gen (S3, Daytona & Tiger manuals checked) are all 0.8 ohm coil primary resistance. I would think the TT600's would be the same?

IMO that's close enough & on the good side - slightly higher than stock. A bit less current will flow, but it's almost certain the I (current) squared element of (spark) energy built up in the coils will be compensated by slightly increased inductance, as the two parameters are selected together for a particula system voltage... so long as they were intended for use in a Inductive discharge ignition (as on ours & all Triumphs & most other big 4 stroke bike engines). As opposed to coils for Capacitor Discharge ignitions which do require quite different resistance (& hence Inductance) parameters (usually higher, several ohms resistance).

In other words I would expect the available spark energy to be just as good.

So, so sounds ok to me?

Thanks for doing the testing guys :)

Maybe you might add a link to this thread & post a few words on my Ignitor thread in maintenance? (And Neil's previous info too.)

Cheers

I have a set of used "sticks" here that I bought for troubleshooting my Sprint. I'll have to take a look at them when the weather gets better and see how they fit up. And I just spent $200 on the Nology coils a few months ago. :eek:

i just did temporary wires for now just to see if it worked, the original red coilwire went to r/hand pin on coilstick and the other straight to l/hand pin, thats all the wiring needed, when i do it properly i will run them along the spine and drop them down behind the coolant hose area,

while rummaging thru my various grommet collection i found a pcv valve grommet used on fords, i trimmed the bottom inch off it and tried it in the hole, it fit perfectly in the recess! and the internal hole is a nice fit around the coilstick too, bonus! so i ordered a two pack and fitted them tonight, i dont think they look out of place at all now the tank is on, i included the part# of the grommets if any one should go that route,[URL=http://s1206.photobucket.com/user/kryptonite1967/media/coilsticks001-1.jpg.html]

Great job, thanks for the info & pics :)

Looks like those grommets (for big old Ford & GM V8 lumps) are not available much this side of the pond...

Dimensions seem to be... 1.22" (31mm) OD, 1.02-1.07" (29mm) ID... rubber feet tips or ferrules, crutch, walking stick tips seem possible options.

well, as i have been dying to try the bike out to see if my low end stumbles were anybetter with these coils i just got back from a 40 minute ride, the temps were at +1 and the sun had managed to dry the roads and the salt! it runs way better! i was slowing in sixth to approx 30 mph and then accelerating and it just pulled where as before it stumbled and coughed and i would have to drop gears, i do not usually ride like this it was just to test the coils, so far it has been worthwhile to do the swap and at a lot lower price than nology option. I also wound it out to redline and it seemed to pull better and no tach issues,

Nice neat job, especially like the black netting stuff you put over the wires. What's it called?
 
#30 · (Edited)
its black braided wiring cover, most electrical supply places have it, we get it from local hotrod suppliers, i will try to find a brand name on monday, it comes in a variety of diameters from 1/8th up to about 11/2 inches i also put heat shrink tube on first , the black cloth tape at the ends is hockey stick tape, you could use just that if you wound it neatly and it would look really vintage!

That looks really good there, cannuck. First rate job.

....and now you have tons of spare room under your tank you can start on the next project:

...either...

Move igniter and all electronics/wiring underneath the tank.

...or...

Modify the tank to make it bigger underneath to accommodate more fuel.



Yes I know - I'm mean :rolleyes:

Correct plug?!

Hey cannuck, is this the correct connector for the coils you swapped over. The fitment is listed as: Ford Ignition Coil Connector 4.6 5.4 6.8 Cobra Mustang Pigtails.

Did you buy those with a harness already or the bare connectors and crimped onto the original coil wires, I don;t remember if there is enough slack to do it.

Here's a pic
