Hi Volks:

Today I cleaned the inside of my AFM with Motomaster electronic spray
cleaner.

First I had to remove lid of AFM. It was held on with a silicone seal,
obviously never opened before.

I ran a utility knife around the seal to cut it. Then I carefully, pried it
open using a screwdriver. I think if you rush this you risk breaking the
lid.

Never having seen the internals, I was surprised at how delicate it is. Like
the inside of a watch!

Anyhow, tracks in the resistive surface were clearly visible. I sprayed it
with a liberal amount of electronic cleaner spray, and moved the wiper
across the track several times while it was still wet.

I also ensured that the central contact pivot, which rides above the
assembly on a post, was also clean.

When dry, I closed the lid, and sealed it with electrical tape to keep it
clean and closed.

So far, no bucking etc, seems to run with nominal performance. I'll know
next time I go for a long drive if it is a good fix.

Thanks to Debbi (MtnGal) for this suggestion!
