Just got a TW125 as a bad runner, it’s now packed up altogether because there was no spark. I replaced the CDI box and ignition coil because the pickup coil resistance (626 OHMS) check was OK, but still no spark? I pulled off the side engine cover to check the pickup coil only to find that it is magnetized. Is this right? It only gives out 0.16 volts when I turn the engine over (I thought it should give out 2-3 volts) a continuity test proves OK and there are no shorts to earth in the pickup coil, I cannot get hold of a coil to check whether its meant to be magnetized or not, or to test as a replacement, Help
