I am finishing to complete my document on troubleshooting the EFI/Electronic ignition.
The last chapter I am working on is about the ignition coils.
Knowing that an ignition coil is essentially an autotransformer with a high ratio of secondary to primary windings and the primary and secondary windings are not actually separated I did some test.
On a set of K75 coils, I can find a resistance between the primary and secondary.
When testing my spare K100 coil, I get nothing.... Nada!
I never tried this coil on the bike and it could be a bad one.
If you have a spare coil, could you please take your Ohmmeter and report what resistance you find between the primary input and the coil output (spark plug wire)? The K100 has 2 output on the coil but both of them should show the same resistance in relation to the input.
If we find the value of the resistance, this could be a big help when trying to troubleshoot an ignition problem.
Thanks
Bert
