Has anybody done it? I see you can send them out to a company for $225 for a repair but I would rather put money in someone here's pocket or maybe have a tutorial/description of what to do. Running out of spare units.

I've never seen anything online about it, I do have one here in unknown condition from a car I parted many years ago if you have need of another core.

I seem to remember someone using window defrost repair paint to repaint the contact areas. Take it with a grain of salt though.

If I remember, I will look at an EA82 flap-style and see what the innards look like. (I assume that they are probably close in construction.) If you have opened up one of yours, a posted picture of the resistance-surface/wiper might be useful.

Let's see if I can add a picture...
Edit: Well, apparently I have no clue how to do this on the new software. Too bad, 'cuz I had a pretty decent pic of an 85 EA82T flap meter. The EA85's on first blush looks rather complicated, with multiple resistance paths. I think if I stare at it long enough it will makes sense.
Anyway, the common thing to do with this style of resistance-film/wiper arrangement seems to be to shift the contact tracks so the wiper's contacts are tracing over un-gouged film surface. A way to go about that on the EA82 version would be to put a slight chicane/s-curve in the wiper arm, drawing the contacts closer to the wiper pivot. Alternately, you could elongate the resistance board's mounting holes to allow some fore/aft adjustment.
While helping a friend resolve a Volvo TPS issue, I looked into repairing the film, and it is a bit of a pain. The common practice seems to be to add a particular type of graphite into a binder (can't remember offhand what they used, but it was common), and experiment with different ratios of graphite-to-binder until you got the proper resistance per unit-length.

These should be helpful.
Think I may have posted them previously.
Haven`t tried it myself.

I bought one from an importer once that was faulty and he replaced the board in it with the cabon tracks on it, I dont know where he got the board though.
