My upright has the original Iso transformers but the large yellow ground running from the 240v Iso isn't grounded anywhere. I thought I saw a pic of another machine where that was the case also, but it doesn't seem right. Any ideas on that?
Also, I have what looks to be a ground and another wire that are not connected (see pic). They appear to be either part of the marquee or the on/off switch on top of the cab. I haven't taken all this apart yet so I don't know for sure. Any help on that would be appreciated too!
