Neil,
Thanks for alerting me to the video. Here is the link to the thread and
video. "
http://www.thesamba.com/vw/forum/viewtopic.php?t=369815&postdays=0&postorder=asc&highlight=tencentlife+afm+video&start=0
"
I had previously tested without power to the AFMs and noticed a linear
change in one and a jerky change in the other. From the video, it appears
I need power for the proper test and will try that later today.
We had a pretty hefty thunder storm yesterday afternoon and early evening
and I lost my internet cable connection which is still out and it appears
that my cell phone is bricked. Off to the store to see about a replacement.
Thanks,
Harold
