Re: [T3] Spark plug wire question


Thanks for helping with the quick explanation on trouble shooting with the inductive
pickup on my timing light.  The rotor problem is taken care of and the resistance in the
SP Wire is spot on.  I did note that my VR is low (13.0) so I am going to retest it after
a long run and if it measures low again, then replace if necessary.  There's a bit more
explanation interspersed below.  

Again, thanks!

Thanks, I knew the inductive pickup had some helpful troubleshooting, but I was not sure
exactly how.  The resistance on the SP Wire is ~1k ohms so it's okay.

Also, with my rotor problems, I found that replacing the dying battery in the multimeter
did wonders.  The BOSCH rotor (which I thought had infinite impedance) is about 4.8-5k
while the un-named bad rotor does have about 0-200 ohms resistance.  The car is running
better with the BOSCH rotor.
