LD electrical spark problem

Recommended Posts

Hi, my ld 125 has developed a spark problem.  I ground the spark plug to the engine and get no spark but when I ground it to the passenger foot rest (only painted metal)I get plenty of good spark.  I tested all the grounds from engine to chassis to the coil  and all grounds are good.  I also tested the kill switch wire and all is good.  Ive have a couple of knowledgeable neighbors look at it and we all just scratch our heads.   Does anyone have an idea as to what is wrong. Thanking you in advance.

What are you considering good? When we were trouble shooting some lighting issues on my LD we found that anything more than .4 ohms of continuity resistance was too much and the lights wouldn't work. Ground points between the frame and motor need to be very clean. It sounds like the coil to frame is good, you just need to clean up the frame to coil and motor grounds.
