Nearly everyone reading this has has a similar story, so here's mine.

A couple of years ago I fixed up a basket case JD A for a friend. There was no generator so I picked up a rebuilt one and stuck it on.

Now I have it back in the shop to get it ready for a show and the generator quit charging while I was running it. After the usual quick check, I pulled the band off and discovered black tape wound around the generator in place of the paper gasket. The tape had sagged and made it's way into the brushes. After some cleaning and fifteen minutes to make a gasket, it's charging again, but I'm a little irate about paying good money for shoddy workmanship. Jim
 
At least someone tried to do it right, they just made the wrong choice of materials. I have removed that band on rebuilt generators and found absolutely nothing under it.
 
The shop we use uses black electrical tape and I've never seen a problem with the tape sagging. In fact I've used tape myself when I've opened one up that was "field repairable" and never had a problem. Using electrical tape instead of cardboard assures a little better seal under the band but you've got to use a good quality tape (Super 33 or Super 88 are good choices), not the cheap stuff. In your case, they had the right idea, just used the wrong choice in the tape.
 
I don't do much generator work, but to me using tape doesn't complete the job right.

The end of the tape came loose and was dangling down rubbing on the commutator. The rest of the tape had separated apart and was drooping pretty bad. Took me about ten minutes to make a paper gasket for it. Jim
 
I just had the starter apart on my Case DC and there was nothing under the band, and I didn't think anything about it until now. Should it have a gasket of some sort?
