Tralfire stator test
Does anybody know if you can test the stator on an 82 trailfire with an ohm meter, and if so, what are the spec's ?

Re: Tralfire sator test
yes. i have specs that are supposed to be correct-if i can find them.

Guys, it is very difficult to bench test a stator. They will test good but fail under load.
Re: Tralfire sator test
Maybe better to state that they CAN test good on the bench and fail under load.
Testing for opens, shorts and bad connections is good.
Yes, under load high ambient temps CAN change the characterestics of a coil.
But knowiing it tests good on the bench is better than going in blind.

Re: Tralfire sator test
Todd. Obviously if it tests open on the bench it is no good. My experience has been with stators is that a suspect stator will test good on the bench but will fail on the sled. It can be properly tested on the bench with a megger but again " my experience" is that an ohm test is not reliable. Most stators go on an intermittent basis, they rarely flat out fail. I wasn't trying to offend or upset anyone. Just passing on what I have experienced. Peter
Re: Tralfire sator test
A megger is a great tool but rather expensive. I have access to one at work but do not own my own.
I feel that an additional "test" is to give it the ole eyeball test. Looking at the stator out of the engine can reveal cold solder joints, burned insulation, bare conductors, corroded connections and grounds. Don't forget to sniff it too. That tall-tail smell of roasted varnish is a giveaway.
Plus if a guy is dealing with points there is no substitute for removal and proper cleaning, inspection and relubing of the wipers.
Often one finds issues with corrosion behind the stator plate(back side) that would never be noticed if it was checked in place.
Your point is well taken about failing underload. Heat is the enemy on many old coils. If they are out of spec at room temp they will surely be even worse or at total failure as the engine reaches opperating temps.

Re: Tralfire sator test
I have never really heard of the Kawasaki stators being problematic. I really think they get blamed for a lot of other issues. Now triple Ski-Doo stators ........... that is another story.
