WR500 No Spark

Hello everyone. Unfortunately, after one summer's worth of fun, my ski
wont start. I didn't expect it to die so quickly when I bought it but
being inclined to learn I decided to try and repair it myself. I have
reseached the group thread but none of my numbers match the numbers
posted when testing for resistance in the electrical box. I was
wondering if anyone could shed some light on the situation with
schematics or diagrams of some sort so I know exactly what to look
for. Electrical work is not my specialty. Thanks in advance to
everyone.
