Hey Del, Look what I found!!! An original Miller Gauge tester!!!

It has changed at some point with software. The attachments are the problem. If you can upload them to an offsite photo host, like tinypic, photobucket, etc, and then just link them, there's no problem.

I just now bought a Borroughs tester off ebay. Nothing special, it's a pair of pots and a sheet of paper, LOL

My a/c delco tester is identical to that including the instructions glued to the inside. Only difference being mine has three knobs for adjusting your ohm output.
