QUESTION: they are black and i am going to change from eletronic ignition to points&cond

ANSWER: Changing from the electronic to points wont help if the coil or plug wires are bad. If you change to points you will have to change the coil. The coil you have on there does not have enough OHMs
Good luck and happy riding

QUESTION: what should the resistance reading be on the plug wires and the ohms on the coil.And what coil should i use with the p/c if the plug wires and coil arenot bad?

Answer
the coil should have 3.2 OHms on the primary side. Should be around 15,000 on the seconday side. Plug wires should be around 10,000
If you change to points, then you need to get a coil made for points. Accel makes a good one
Good luck and happy riding
