Resistance in spark plug wire

[520John]

Hi people.

Does anybody know what resistance (ohm) it should be in the spark plug wire (the one going from the coil and down onto the sparkplug)??

Depending on the accuracy of your meter - really, really close to zero.

I set the ohm meter to 200k and it measured 2,4????

Spark plug lead resistances are generally very high iirc. Something about noise supression.

So its ok with the 2,4 at 200K??

yeah that means 2.4K ohm resistance, it's probably fine, though someone will have to find the stock spec for the leads...

I remember something in the Bentley's about there being a .1 or lower on the M50's coil-on leads

I also seem to remember that spark plug leads have a resistance of a few kOhms. 2.4k sounds about right to me.

When I was researching the plug wires for my '89 with the M20, I was looking into making my own wires and had found a few places that sell the plug wire ends. The ends are 5000 Ohm resistance.

Spark plug wires: 0 ohms (appox.)
Spark Plug ends: 5.0 +/- 1.0 kohm
