would like to know what wires are used to hook continuity light and buzzer up to set timing on 71 puma 440. service manual says both black wires from motor. I assume they are hooked up individually and other lead to motor. my motor has a red and white from motor. only black ones I see are coming from the external coils. do I hook continuity light to them(black ones) or the ones coming from motor(red and white ones). service manual I have don't show coil resistance or how to check them is there somewhere I can find this information or a more detailed service manual? thanks
