This is how I checked my 200W before saying it was an autotransformer. N was not grounded.

Yes. 20-70 ohms depending on the combination (In/Out/N/L). Plus probably a capacitor somewhere between N and L judging from the meter's slow response.

But I am not the OP, I am just exploring...

The meter's slow response may be due to the inductive affect of the TXR, similar to a capacitor.

Thanks you so much for your help. I had this transformer delivered over the weekend and it fixed the problem. As it turns out, it was a grounding issue.

You are a genius; and thank you so much once again for recommending a great product.

Well between myself and StrongEagle and the others you have a few decades of electrical engineering experience contributing. Glad to see the issue resolved.

PNGMK, you do yourself and SE a disservice. As old as you two old coots are, I'd say a LOT of decades of experience! :lol: :lol: :P :mrgreen:
