In the tech tips it states to use a 2000 ohm resistor 1/2 watt. Could not find one at radio shack. Can I use 2 1000 ohm resistors in line?

You SHOULD be able to find a 2K Ohm resister. If not, try a 1.8K ohm. Either one should work. The other way of trying it is with 2 4K ohm resisters in parallel. That will give you 2K across them.

The local radio shack didnt have one. I bought a package if 1000 ohm resistors thinking i could install 2 of them in the wire.

Hey Ray,

I'm no electrical guru, but I thought my understanding of basic resistance is that it's additional when in series....like the Ballast resistor which is 1.5 ohms, and the 1.5 ohm coils which has a total of 3 ohms resistance which is what the TCI needs to see!

SO...two 1000 ohm resistors in series should work the same as two 4k ohms resistors in PARALLEL. I remember being informed about 2 parallel loads puts 1/2 the resistance vs. a series load.

ZX11..if you have an ohmeter, wire the 2 resistors together and test them with the meter, I would expect it to read close to the 2k value.
T.C.

Yep, that's the way it works, except for parallel resistance is a little more complicated than that.

Actual value is not that critical...seems there is a lot of leeway. A 2.2K Ohm works just as well.
