Super High Ohm Reading From Stator 1977 XS750 - RESOLVED

So I am not charging. I check the Ohm Reading from between the three yellow wires from the Stator and got 6.4 Ohm each time. 

Is my Stator totally fried? 

 

Thanks, Dan.

Do you have a manual? It will tell you what the resistances should be.

I wouldn't call 6.4ohms a high reading though?

Right OK then it is high. Much higher than it should be it seems. 

Does the bike run? If so you can check the voltage (carefully) on these wires. It will be AC at that point. 

The only other thing to do is whip the cover off and check the windings to see if they're burnt up

 OK I can do that. Would I expect to see 13-14 volts ac between each pair od wires? 

I did visually check the Stator and it looked OK. Just a little dirt but not burnt or cracked.

No it should be much higher, 60v AC up to around 80. May well vary with engine rpm.

Measure between the 3 yellow wires again

Just wanted to come back and report that the charging problem has now been resolved without buying a single part.  Turns out the field coil wasn't being energised due to a broken wire.

Thanks for the help anyway, Dan.

Well done mate. It's great when the OP comes back with an outcome
