Now that pesky TPS. I've attempted the adjustment about 3 times, (even bought a new one). Used Roger Browns write up.
Maybe I need yo go back and mess with it again Looks like I really need to learn what ohm setting to use on my ohm meter. <img src="/forums/images/graemlins/rolleyes.gif" alt="" />
Well, since you want to measure at most 10,000 ohms (10K ohms) you need to set the meter on a range that will measure at least that much. So 20,000 is greater than 10,000 so that would be good.
Meters vary in how they show infinite resistance, some have a sidewase "8" for infinity, some flash, etc. To see what your meter does, set it to ohms (any scale) then hold one probe in each hand (i.e the tips apart) and see what the meter says. You can also verify the meter is working properly by touching the tips of the probes together, it should read "0.00" or something like that, short circuit.
One suggestion you might consider is head over to Radio Shack and pick up a resistor or two of some common vallues, like 1000 ohms (1K) and then you can practice taking readings with it. For example on a 200 ohm meter scale, it would read infinite or over-scale, on 2000 ohm scale, it would read 1000 or 1.000 (if it reads in K-ohms), etc. Since you know what resistance it should be, you can verify that you are using and reading the meter properly.
Resistance is probably the hardest thing to measure, if the probes don't make good contact, or the surface is dirty or you have the wrong scale or plug the probes into the wrong terminals on the meter, you'll get a reading of some sort, but its likely to not be the actual reading.
