Suggestion for those needing gauge/ sender test resistors

There are a number of 100 ohm, 25watt rheostats showing up on ebay. I DO NOT HAVE A HORSE IN THIS RACE, and do not recommend or not recommend any of these over the other

All you have to do is to set the resistance with your (accurate) ohmeter. You could mount these in a small box, with a pointer knob, and carefully mark the 3 well known resistances

I have no idea why the software has to put stupid titles these are three different ebay links

I bought 9 - 10 ohm 100w ceramic resisters
And 9 - 1 ohm 100w ceramic resisters.

I put the10s in series and the same for the 1 ohms.

With a clip lead i have 1 ohm increments from 1 to 99 ohms

I went with 100w so there was less of a likelihood of the resistant changing the closer you get to 10 ohms and the current goes up.

^^Homebrew resistor decade box^^ Back in the day, Knight Kit, Heathkit, and Eico, and some others "factory made."

I even bought a series of switches to switch on and off resisters but never found a box suitable to fit everything

I used to know a strange old man, used to dink around, he had I guess a hundred small pieces of 1x4 or 1x6 maybe 4-12" long, he'd rig stuff up with small brads and solder everything together. A REAL breadboard, LOL

We have an old Heathkit decade box where I work, still being used to set up production electronics. They're pretty useful.

If you're looking for boxes, Hammond Manufacturing or Bud Industries sell a lot of metal and plastic project boxes for test gear. Stuff like this: General Purpose Metal

Reminds me of making your own factory harness. Hang your harness on a piece of plywood, unwrap it and change one wire at a time until you're finished and rewrap it. I knew an old-timer that use to do this.
