Testing Stator of spare block?

Hello,

Recently I bought an spare engine block for my gs750 1978.

I picked up the block without carbs and starter motor, but the rest is pretty much complete.
So there is still a stator with the 3 connection attached to the motor.

Now I was wondering whether or not I could test this Stator without putting it in my "main block" ?

Kind regards
 
You can check the resistance and continuity of the wires but you will need to have it in a running engine to test the output voltage.
 
But, That won't say much about the stators condition will it?
 
Might not look cajun crispy, but look for subtle signs of heat damage- here's one of mine

Picture would help a lot. Signs of burning is not good.
In my case a PO had replaced the stator but chose to splice the three wires with poor connectors inside the casing and the inevitable happened. The stator survived.
You could check for shorts between each leg and ground and between each leg. Resistance checks with multimeters are not very useful and as said the best test is output voltage between legs at 5000 rpm. Ideally you want 80 Volts ac obviously although I ran my bike for a summer with a replacement that wasn't wound the same with only 55-60 Volts.
Have a look at the pic, post #8 in this thread http://www.thegsresources.com/_foru...onfirm-I-need-a-new-R-R-and-stator&highlight=

First off, as Hillsy sa, it's always been easier and more reliable to just put the stator in a working bike temporarily and try it.

but yes, you can (assuming camchain is there and motor turns ok, you can find a way to spin it (with the plugs out) and test ac output...if you have an easy way to get a hold of the crank and spin it with an electric motor (or a strong fast waterwheel or air-drill).... The starter motor cant spin it fast enough to be useful and it's not good to run it very long either...

Static methods are going to want a More Than 12 volt supply to be convincing so get out the rubber gloves, a bunch of alligator clips, lightbulbs or heating elements(as handy dummy loads without $) etc and still without the assurance of seeing its output.
