I'm an electronics guy so my favorite place to buy electronic components is Digikey.com. There a other sites as well, but I find them to be
competitively priced and fast, cheap shipping.

I've never noticed the resistors of which you speak, but then my gauge panel hasn't given me any trouble. So I can't comment on the size (wattage) or
type of resistor you need. Hopefully someone else can chime in with that info.

Just for fun I went looking on Digikey. Power resistors are not as popular these days so looking for what they had in stock, and the closest values.
Both values below are within 5% of your measured values. Also calculated the Max power for the values @13.8V is 2 watts. Since the voltage across them
should be well under 13.8V, I'm guess 2 watts is plenty... it was also all they had in-stock!

82 ohms PN: OY820KE
100 ohms PN: OY101KE

Both are $2.45 each in single quantity.

Either I screwed up but from memory red, blue, brown is 260 ohms. The 4th band is the tolerance and black is not a 4th band option color.

I will go find an resistance chart on the Internet and verify this posting .

Mnemonic

Bad - black - 0
Boys - brown 1
rape - red 2
our - orange 3
young - yellow 4
girls - green 5
but - blue 6
Violet - violet 7
gives - gray 8
Willingly - white 9

1st band - 1st significant digit
2nd band - 2nd significant digit
3rd band - multiplier by ten (number of zeros)
4th stripe is tolerance, probably doesn't matter here.

So red blue brown black should be 260 Ohms, 20% tolerance.
2 6 1 20

A more "genteel" version:

Black - Better
Brown - Be
Red - Right
Orange - Or
Yellow - Your
Green - Great
Blue - Big
Violent - Venture
Gray - Goes
White - West

IIRC, 5% tolerance is Gold, 10% tolerance is Silver, 20% tolerance is blank.

I didn't learn Johnny's version until US Air Force electronics school!

Geez, in 60+ years of soldering, never heard that mnemonic. Learn something new ever day around here. HOMES was another (non-electronic) one.

I was going on the fact he mentioned 4 colours, then red, blue... and brown, black. I don't know of resistors marked with 2 colours and his measured
values don't line up to the colour code.

So I assumed this being automotive his mentioning they were ceramic (which usually have the value printed on them rather than colours), I figured
these were likely made to GM specs and have no relation to the electronics marking standards.

I bought a small piece of ham radio gear once. (A GPS tracker). It was assembled in Mexico. None of the resistor colors matched the codes I know and
the schematic. I just used my ohmeter to measure them. I have no what the colors they used really meant.

Never heard of HOMES, to best of my knowledge. I believe the one I posted may have been in ARRL handbook.

Just for fun I went googling to find more info on these resistors. I found this pickup-truck parts place that has gauge resistors in their catalogue.
Page 46 in the left corner of the page... $15.00

It doesn't say the resistance value or any further info. GM seemed to use 0-90ohm sensors in that era, so I'm guessing the value of the resistance
sets the meter reading.

http://www.truckandcarshop.com/6072.html

Its just a resistor, so if you could determine the resistance and measure the voltage across it to calculate the power dissipation, any resistor
meeting the specs will work. There are variable power resistors that may work for you as well.

I'd pull mine out, but there are some spring fingers holding it in place that are a bear to work with.

The dash gauge ones are the flat rectangular sandy ones with wound wire I remember no color code as not round carbon type. I’m assuming the rear
gauges are same?
