i put old coil back on and got weak spark but only with spark tester on it. tested switches they check out good. now trying to check pick up coil resistance and source coil resis. i have a clymer manual. it says unplug wire at cdi and to check red to white with 459-561ohms. but there is no white wire. (thats for the pick up coil.) then source coil is the same but it says check brown to green. but there is no brown or green wire not sure if the book is misprinted or if i'm not testing it in the right place. whats the best way to test what else should i test.
