PostSubject: Dim Bulb TesterA new project   2013-10-09, 10:14 pm

The other day I finally built a dim bulb tester.
When I used to work for a TV shop we had one there I used all the time.
A friend brought me a stereo amp that was blowing fuses, and so I finally decided I needed a dim bulb tester of my own.

Normally I was using an isolated variable voltage power supply with built in current protection; but it was not really adaptable in this case.

Going thru the electrical stash in my garage I found a nice control(?) box with no cover, a used wall switch, a used duplex grounding outlet, and an old Bussman screw in fuse box with cover,(The same size as a standard duplex wall outlet plate) and the original NOS fuse in it brand new!

Grabbing the parts I mounted the fuse box onto the control box after removing the metal cover. The old glass fuses are the same size base as a standard light bulb.

Mounted the switch, and bulb on a metal double duplex adaptor plate and the outlet directly to the box. A power cord cut off an old satellite C band receiver and a strain relief from a metal outlet box completed the project, after a coat of paint.

I'll try to post a pix later on when I am more mobile again, after my fall earlier this week.
I tested it out and it worked great- as I expected.

I did measure a few microamps of leakage though, to the metal chassis, which is connected to the ground pin on the power cord. This may be because I do have the chassis ground connected to the metal box its built on. I suspect if I opened the ground, the leakage would go away, but I prefer the safety of having the outlet grounded. It plugs nicely into the Powerite I have too, so if I want, I can vary the input voltage

Did you finish your tester?
Any pictures to help brag about?

Done and painted.
Sort of ugly looking too, but works great!
No way to post pix. Can't figure out why my Photosuite wont re-load on the computer.
I can post when I get that figured out.
It was on before the crash and I told tech to remove it and I'd reload. Bad idea.......
