Took my 05 sprint to a dealer to check the reason for no spark. He said it was because the alternator was not any good.. Stated pick up running was .258 kilo ohms should be .568-823 also shorted through frame to battery, as did not show ohms when connected..
Anybody ever hear of no spark because alternator no good?

Are they trying to say that the stator is beat so it won't charge the battery and the low voltage condition is what's keeping the bike from running?
If so, that makes sense.

If there's enough battery current to crank the engine, alternator has absolutely nothing to do with creating spark.
You can disconnect the charging system completely and bike will still run as long as the battery is charged.
(that's not to say there might or NOT be a charging system problem - just got nothing to do with spark)

Sorry - your info/data is quite confusing ........
Have no idea what a "pick up running" resistance is, or to what those numbers refer.
And "shorted through frame to battery as did not show resistance when connected" really doesn't make a lot of sense either I'm afraid.
Do you perhaps mean "Stator shorted to engine because it showed zero resistance (i.e. zero ohms =short)
"not showing resistance" could be interpreted two ways - either there is zero resistance - which means short - or is Infinite resistance - which means 'open'.
Typically when a layman says NO resistance it often suggests there is no resistance reading therefor it is 'open'
Literally however 'no resistance' means it would be zero or short

Stators are pretty much always going to be open (good) or dead short (bad) - there is really no in between.
The type of numbers you quoted sound more like R/R checks - but again, that is not what is causing no spark.

I read it to be you've got a dead battery due to a dead stator and that's why the bike isn't starting.


This makes sense.
Although, if the dealer replaced the battery and the bike started right up, that seems like a detail worth mentioning.

Can we get some clarification OP?

No the bike was never run at the dealer. I had battery tender on and the battery alwys tuned the engine over. I talked the the mechanic and he said they had check the alternator and there is another box that is attached and if the alternator doesn't charge this other box is the one that controls the spark.. THey wanted 825 to fix I told them I changed alternators before and that problem did not happen..
Any idea what the attached control box might be??

The only other boxes I can think of are the rectifier or ECU, they're both kind of box shaped.
Is this a Triumph dealer?

I was wondering whether the "pick up" it's referred to in the first post may be the crankshaft position sensor.
So the usual questions are:

-does it crank over fast enough and w/ a constant speed (video is always great for that matter)

-do the injectors spit fuel?


Anyway, paying more than 800€ w/o knowing clearly what is the root cause is frightening.


In addition naming the ECU "a box that is charged" is rather strange unless the mechanic feels that the listener wouldn't get what is the ECU. Well for sure "powered" would be better than "charged". The only thing that is charged is the battery.
