Im trying to do a ignition coil test with a multimeter I bought.I have a HELMS, I took of the dist. cap.Then it shows a pic of the rotor wheel with a screw coming from behind and underneath the wheel.I can not get that screw loose.Is there a trick to this or anything.Im using the correct phillips screw head and everything but all it wants to do is strip the head.

Anything safe to spray on the screw to help loosen it? WD40?

Also the tip of the rotor is burnt a little bit.Would that be a bad coil or ignition switch or ignitor?

 

i have the same problem. i bought a ignition kit from acura, installed the wires, cap, but still have the rotor in the bag.

 

Anybody?
