Looking for spark:
Need to know things about the Honda 600.
- Both plugs need to be attached to the coil and grounded if out of the engine to complete the circuit and give a spark. If either is not connected then there is no spark.
- Because the wires are screwed into the plug connecting ends (caps), these need to be looked at to ensure they are touching wire and not just insulation.
- Also the caps are manufactured with a small wire inside to grab the threads at the end of the plug is this wire is missing (and some are) then it will have a poor or no connection to the plug.
- You can check to see if your coil is good by using an OHM meter to touching both leads to see if they are connected. If you have a reading at around 32 it is a good sign. Do the same with the black and blue wires, they should also have a reading. If either of these checks come up with no reading then the coil may be the problem. But, using a needle push it into the base of the wires to see if there is a reading there, as many times the wire is broken at its base causing a disconnect. There is a fix for the coil on the
anzhonda600owners group site. In the 40 some years I have been working on old cars wires seem to be most of the problems.
