Xpl 98 week spark 947cc

How do I measure the volt to the coil. In the manual it says that at least 20vdc should be deliverd from the mpem to the coil by the white wire. I have 0.3vdc when the wires is still conected to the coil. If I mesure on just the wires with out the coil i got -160vdc very strange.

Back up to your trigger coil on front of mtr. Black wire and black yellow gray plug mtr front. Resting impedance is a quick 187 ohm Flash. 951 problem start there with Rusty stator or Bendix that lost a tooth and destroyed trigger pickup. Ignition coil typically works or doesn't work noticeable by huge bulge in the side of it

Thank you for your replay.
I have the mantance book. So measured resistance is 240 ohms. Trigger coil 0.25vac. Avery ting is clean and looks ok. Replaced all grounds and have one extra ground for the moment. The only thing thats out off specification is vdc at the primary wires to the ignition coil. Is there a way to test it?
Thank you for your time.
Best Regards Martin.

If I mesure from positive on the battery to white cable on the coil I have 0.5vdc in difrency. When i puch start it reads 33vdc. And that souds right to me.
