What about resistance at the coils? Not sure if I'm remembering this right, but I think it should be 3ohm's. Anything different and the unit wouldn't work properly or maybe at all.? Just a thought.
 
Post 11&12 said it it was most likely a failure, and I would add as I said in my original post do not to stand for any of this nonsense about replacement at cost! unless you have owned it more than five years or clocked up 30,000 miles on it, if not, it is not fit for purpose, British sales standards say so!
A free replacement is the only re course in these instances.
I bet you, as in Reggie's case and loads of others I have heard about, no fault can be found but, a replacement will be provided at cost :twisted:
do not accept it, you bought it through a British supplier and therefore British sales regulations apply,
Good luck!

Are you guys using resistor plug caps.

All digital ignitions seem to require these, I see that Trispark don't mention this in their twin installation instructions, but do so in the 3 cylinder instructions and the trouble shooting guide.

NGK 5000OHM plug caps are cheap and easy to find.
 
What would happen if the electro ignititors HT path had all 3 R factors installed, ie: the HT lead, the plug boot and the spark plug? Extra power spark to blast thought the R factor or sucked down to put fire out?

Hobot mentions the possibility of 3 resistors in series. I could see all that pent up energy having to be absorbed by the TriSpark components, overheating them, and causing failure. Similar to kicking over with no plugs at all to check compression, etc. Not good for electronics.
Maybe those with problems should check and comment on what kind of wires, boots, and plugs they are using.

From what I've read many EI boxes are susceptible to RF interference...RFI can be greatly reduced by resistor caps, or resistor plugs, spiral wound plug wires, etc and generally one of these things will do the trick, no need for all of them...am using spiral wound wires on my bike and have no RFI problems
 
When I got my Trispark from CNW I also ordered their recommended dual lead single coil and resister plugs and wires.

Two and a half years later now and not a hiccup.

RFI and shock from not having a plug or gap to let the spark go. Hands up Trispark users that have run without resistor caps or pulled a plug lead whilst the engine was running, or timed the igniton, powered up with no plugs connected.

Any of these things, plus a few more can cause failure in the electronics. Maybe why some have issues and others not.

Been wondering that myself...

I think that it is good to check the resistance on your plug, wires and cap. In the airhead world it seems to be customary not to use resistors in plugs or wires but to use a suitable cap. I don't know if there is any reason for doing this.

Other electronic ignitions are also fairly prescriptive in what types of coils are required, usually needing 3 OHMs and those systems with the best instructions will specify which types of coils should be used

Sachse electronic ignitions won't cover lack of resistance in their Gtee and are very explicit in their instructions to use suitable plug caps. Silent Hektik ignitions get over the issue by selling you the coils, plug caps and leads. Silent Hektik have been claiming a Triple Spark on their units for some years now, but only if you use their coils.

I got the same set up from CNW and very happy with it.
 
Essentially all electronic ign list to put 5000 ohm's in HT path, and so essentially all R factor plugs and plug caps and a couple feet of R factor plug wires all come in about 5000 ohm units so 3 in a row would be 1500-ish ohm to over come or not. Does it matter, I do not know so experiment please and get back.
 
Hi,
Just to let you know, I fitted the replacement Trispark unit today. The bike fired up first kick & once strobed ran perfectly. The new unit looks just the same except for white resin in the back instead of black. Phil at LP Williams assures me this one will not fail. Watch this space.
Thanks to all who posted replies.

Cheers,

Martyn.
