Ok, I would have bet my hat it was red, red, black, black, red? .........And I have a multi meter, can you explain how I can use it to determine the resistivity of the resistor!
Put your multimeter on the ohms measurement setting, if it has different ranges, then choose one that measures ohms in the tens of thousands (typically a 20K scale, and measure across the resistor leads). I'll bet you get 10K ohms
If the color bands were red, red, black, black, brown, that would make it 220 ohms 1% tolerance and that would be exceedingly rare to come with any avionics stuff sold on the market recently. Notice that there's a bit wider gap between the two red bands... generally resistors have a larger gap between the "measurement" bands and the "tolerance" band, that way you know which end to start reading the colors from... the tolerance band is always read last.
BTW, I looked back at some of your previous posts and it looks like you've already bought a Dynon Skyview system? If so, then I'd bet a cold beer that those two 10K resistors came with it. If so, then you're probably going to end up having to use larger than 10K on the P-leads anyway. I've wired up two Dynon D120 EMS systems and with Slick mags in both planes, have had to go as high as 120K ohms on those resistors to fix the erratic readings at higher RPMs... 10K is just too small a value for most Slick mags.
As for sourcing a 1K ohm, 1 watt resistor, I'd just go to your local Radio Shack and see if they've got one... but you might better hurry since the latest financial news sounds pretty grim for RS even though most folks have thought they've been on the verge of bankruptcy the past 25 years or longer but this time is sounds like it might be for real.
