Actually not that long a while
Been busy, work, family, ya'know....stuff.
I have not touched it in a week, as I come home late, and all I have energy for is just being alive in front of the TV.
Anyways, today I figured why my Shadow meter no workie-workie.
The reasons are many:
1) The lamp was bad. Somehow stupid me did not realize that the meter employs a separate lamp and it is no longer being ..well....incandescent. The lamp that lighted the scale was, and I thought all was copacetic. It was not.
Well, I used a bayonet lamp of the same format in the scale lighting and I moved the scale lamp to the shadow meter (the scale uses a clip, but the shadow meter uses actual screw socket).
2) at that point I had to adjust the lamp to produce the shadowed pattern. Then I realize the bar does not move at all.
3) I measured the coil again, and then I thought that the coil should not be a short, it should be about 1Kohm (roughly 1000 feet of 40 gauge wire times 1 ohm/foot). Then I saw a non-typical wire under the chassis and it was shorting the shadow meter coil. Hence the short. I opened it. The coil is open. No continuity at all.
So, now I have to see how to remove the coil itself and rewind it. I read the instructions at the Philcorepairbench, but the removal is not clear.
Anyone?
PS. ANother option - to buy another shadow meter. Separately.
