Plug and play, I swear I did the stator tests as instructed and it passed. I will do them AGAIN and see what happens.

I've been a motorcycle mechanic for 15 years and electrical has always been my Achilles heel, I can do all the mechanical like it's nothing but electric will stump me sometimes.

With a new RR in it I will bet now it is the stator but I will do the tests again.

The first simple one for stator is isolation test - unplug the stator and measure resistance between any one of the three terminals to engine ground: this should be 'open' or infinite resistance.
If it fails and you get 'short' (zero ohms) to ground, the stator is toast. (If fails, no real need to do following test - that is already conclusive - although can't hurt any worse.)

Then leave stator disconnected and start bike: measure AC Volts between the three possible pair combinations i.e. 1-2, 2-3; 1-3. All should be the same at any given rpm
i.e. check at idle and at say 4K rpm - the numbers themselves less important, their comparative values are what are (make sure throttle is constant when you measure at the higher rpm - lock it somehow so cannot change as you measure your three different pairs)
Do you work in a bike shop in Bay Area? I can stop by one day this week if you like, take a look at it for you - drop me PM if you would like.

I work at Road Rider, I'll be in the shop every day this week but the bike is at home. I will redo the tests and see what I get.

Stay Tuned!

Yep, grounded stator. New part on order.

One of those 'good news/bad news' situations - at least you know the problem now, but bites to have to lay out the cost of new part!
Did you go OEM or after-market? I've had good success with my Ricksmotorsportelectrics stator.

Yea, Ricks, also Ricks for the Regulator too. At least both parts are brand new now and I shouldnt have to worry in the future. Just have to get the cover gasket, with Mountain View closed the same as my days off thats a challenge

Probably lucky if they have in stock anyway - order it from MADSS.com - you get 15% off list, no sales tax and free shipping if total order >$40 and it's going to come to your door!
That should be a metal*** gasket - I've had good luck removing without damaging as long as no-one used sealant in the past.
OEM part number T1261098 (that is the part # specific to the Tiger - see note below)

*** hmm - interesting - the Daytona one is metal and 2x the price of the Tiger one (which is same as the Speed Triple).
So I suspect the Tiger one is paper ...........
Even though covers are slightly different (because the stator and rotor are different) would have though the crankcase - and therefor the gasket - would be same?
Safer to order correct part I guess

Got the metal gasket and the job went very smoothly. It was due for an oil change anyway

I have a very strong 14+ coming back to the battery now so this one is a done deal. Thanks for all the help!

Good conclusion to the story

Moot point on oil change now (especially since you said needed anyway) but there is actually no requirement to drain the oil - you only lose maybe 1/2 cup or so when you remove the stator cover.

Interesting that Triumph spec'd different gaskets - did you order under the Daytona part number, or was the Tiger one metal after all?

Sorry for not getting back to you until now, been very busy lately.

I was given the option of paper or steal gaskets by the parts guy. So I took the steel. he did not tell me if the original part number was steel or not.

I changed the oil just because it was time to do so. Might as well as I have the tool box out.

Thanks again for all your help!
