I'm sorry but I'm not able to pull up any specs for those models. Perhaps one of my colleagues can. I'm going to open this up to my colleagues so one of them can help. Please don't respond (even to acknowledge this post)until you get a response from us. If you respond first it will only delay your answer.

Hello, send me a few photo's of the transformer so that I can see what the primary and secondary sides of it are... photo's taken from different angles so that I can see all of the wire connections.

and please tell me why you are making these changes or repairs and if you have a multi meter or not.

Expert:  Phil replied 2 months ago.

To attach photo's use the paper clip icon on the right end of your dialog box tool bar, OR.. the 'attach files' link to the left of your send button.

(note:the wire colors are not standard at all they can even vary with the same manufacturer, we can take ohm and voltage reads however in order to determine the correct connections.)

We can go from there
