i am specifically looking for a 15k resistor. I am making a timing eliminator for my motorcycle. I know that a 15k resistor works (becuase i did it on my last bike) No stores around here sell them (radio shack, and local electrician supply) Even radio shack.com no longer carries the 15k. Now i have tried making a 15k resistor (with a bunch of resitors that equal about 15k) but unfortunately they do not work on the bike. Where do you guys buy things online, or perhaps maybe some of you a few laying around that i could buy? thanks for the help Jimmy

https://www.partsexpress.com/pe/pshowdetl.cfm?&DID=7&Partnumber=003-15K What do you need in watts? Combining resistors sums the wattage capacity, so you could combine in series or in parallel for more watts. Use the Parallel and Series Calculators. ------------- Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

A much better source than Parts Express for electronics supplies is Newark. They'll have what you need. ------------- Support the12volt.com

unless your bike is the same make, model, and year as your last one, you may need a different value resistor...

i actually need a 15k ohm 1/2 watt resistor, and parts express no longer carries them

If I'm not mistaken, and I don't think I am on this....the wattage value of a resistor is just the value of the wattage where the resistor will maintain its resistance value. A 5 watt resistor will change in resistance if presented with a higher power. Which is to say, you can go higher on the wattage value...you can use one that is rated at 10 watts or 20 watts.

Three of these in parallel will give you 15.6666666666666666666666666667 kohms (but who's counting  ) at .75 watts. That is enough power capacity, and WELL within tolerance range. ------------- It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."
