1997 ZX7R no spark.. need help!
Hi, New to the forum, but done lots of reading to find a solution to my no spark problem with my bike.
A little back ground first: The bike ran normally for some time, but then had to
tap the junction box under the seat to get the bike to crank over. After some time using that
procedure, it took longer and longer for the bike to start (would just turn over, but eventually
start). Until where I am now with the problem of now spark, but bike will turn over.
I checked the grey wire to the CDI (has 6 V when both plugs are plugged in to the cdi, but 12V
when not plugged in.
I have 12 V going to 1 wire of each coil (both red), do all 4 wire need 12 V to the coils?
Coils and pick up coils read good.
When I ground out the green and black wire to the coils when bike is turning over, one side
has 4 V constant power, and the other side 0 V.
Any ideas what I could check next or what may be the problem?
Is there a way to "fool" the CDI to throw a spark to see if the CDI or pick up coils are good? Any help is much appreciated.
