Michael DT125LCIII

Hello! Thanks for that quick and thorough response. Ya I was tossing and turning so I decided to post! I was just posting what was in the book. What is a pulser coil anyways? I'll check out those contacts in the next couple days and post what I find. Thanks again! Mike

Hello, I have a 1987 DT 125 LC III that I am just about finished rebuilding. I am getting a spark out of it however it is very weak. I checked the resistance of the Exciter (source) coil and pulser coil as instructed in the manual (haynes) and got a reading of 378 Ohms. The manual says that it should read 180 +/- 10% so between (162-198)ohms. The manual states that if the coil is suspect by this test to remove the stator plate from the machine and take the assembly to a Yamaha dealer for further inspection. Is it possible to test these coils myself? The DT coils can be renewed individually if I can find out which one is faulty, I just don't know how to do this. Or do you have any suggestions as to what else it could be? Does anyone know the steps to test this sort of thing or do I need to bring it in to a dealer as the manual states? If so does anyone have any idea as to how much a dealer might charge for that type of testing and how much coils would cost? Thank you
