Need Help checking Continuity of...
Spark plug wires. i have a Multemeter i bought about a year ago but have no idea how to use it
heres what i have,

Specifically, you are measuring resistance, not just check continuity.
Connections:
Red lead = V , Ohm, mA, Temp
Black= COM
Set the dial to the lowest resistance value = 200 Ohms (symbol omega)
Record the digital reading.

Sorry, wires measure , as a rule of thumb five thousand ohms per foot, so I would put the meter at least at 20K ohms. Good luck!!!!

Try again. What wire were you measuring barb-wire?
I would believe something more along the lines of .2 ohms (2 milli-ohms) /ft.

thanks lucky
i tried it at 200Ω but wasnt getting a proper reading. it was showing "1--.-"
moved it to 2kΩ and got these readings
0.362
0.371
0.377
0.367
0.359
0.371
0.370
0.365
so are my plugs good?

Last NAPA wires I bought Ohm'ed out at about 100 Ohms each. The stockers I took off were in the 500 Ohm range.

I can't speak to the plugs, but the wires are good.

Not according to the post with the manual page-you multiply the number you get by 2000 (the 2K scale) and all of your wires are above 700 Ohms.

On this particular meter, the resistance numbers(on the selector dial) are the range, not a multiplier. His wires are ~360 ohms, which is why the meter read a "1", on the 200 ohm scale. So the next scale reads up to 2000 ohms, which will give a reading in kilo-ohms. .360 x 1000 = 360 ohms.
