Does anyone have a picture of how to attach the spring to the lead wire & how it goes into the insulator cap.....thank you on a 3/4 inch plug.....

With the CM-6 plug there is a resistor in the cap and the end of the resistor goes into the spring

The lead wire is protruding at least half way into the spark plug area of the boot and goes between the coils of the spring

When the plug is inserted, it compresses the coils of the spring against the wire.

The caps using resistor plugs are made different and do not have a resistor in them. I don't have any RCEXL caps using like the NGK BPMR6F resistor plug. Mine are all rubber CH.

I see. I thought that the wire might go into the sharp end of the spring. The spring has 2 folded sharp ends. I figure they go into each side of the wire to secure it....thank you so much

Like this.

Jody, Thanks for a great set of images. It appears to me that the primary contact with the center wire is the two prongs from the spring penetrating it and the extended portion of the wire is just incidental. Dan.

great pics, thank you. I also striped some of the insulation around the lead wire (about an 1/8 of an inch )& put it in between the coils of the spring. When I finished I put the prop on and flipped it a few times & got spark.....yeee hooo. however, I did not see a spark every time I flipped it, I heard it pop every time, maybe a big spark every two or three flips....is that normal

You should get a spark every time the magnet passes the sensor no matter how slow you turn the prop hub. You can hear it spark in the cap but I think it is still better to have a plug in the cap.

If there is no plug in the cap, there is a possibility that the spark will fire inside the timing sensor and it may take out your timing sensor at the hub.

Thats not good! Thats not good! Capt,n Capt,n >>>>>>>
