| NOTE |
| This is what the pulse data looks like when the tone ring comes to the spot with the two missing holes, indicating to the ignition controller that Top Dead Center is coming up in 90 degrees from now. Again, there are 2 missing holes in the tone ring to cause this signal skip as viewed on a hand-held scope-meter. God bless, Fitz. |
