As part of my fault finding I am trying to test my coil. It was part of a Boyer Bransden Micro Power Digital Ignition Kits, KIT00303.
According to Boyer tech support, primary resistance should be 0.6 ohms. Secondary resistance should be "around 2.7k ohms".
I have tested the primary resistance by connecting my ohm meter to the two inputs on the coil, stamped on the plastic coil case as + and -. That part made sense. The coil checked out fine at .6 to .7 ohms.
Now I am trying to check the secondary resistance. How is this done?
I have tried connecting to the - input and to one of the coil outputs, the spark plug wire lead. I got 0. I tried the same thing but + instead of -. Same result. I then tried putting my ohm meter leads on the spark plug wire leads (not using + or - inputs at all). Still got 0.
Is there a trick I am missing? Does the coil need to have power applied to it for the test to work or something? I am testing this off the bike.
Thanks.
