Motorcycle Repair: 1981 minitrail 70 honda, dc volts, point gap

Question
Hello again Mr. Silver.  I had asked you in the past about this little bike and I am continuing to try to get to run.  It has Ok compression but thats not my issue.  It has a 6 volt system with a magneto ignition.  I was getting around 2 volts on my trigger wire from my stator.  The voltage acts a little low to me but I am not sure.  I put a new external coil in it due to bad resistance values in that coil.  I have also replaced points and condenser.  No ground problems I can chase down. I have disconnected all wires that could ground it out.  Is the 2 volts enough to fire this coil consistently.  It fires good sporadically.  Am I going down the correct trouble shooting path.. Thanks in advance Once again.

Answer
Joseph, Are you reading AC or DC volts?  That is an AC voltage coming from the magneto coil.

Did you replace the spark plug cap? Does it have resistance internally or not. Resistor caps will have about 5k ohms. You might try a non-resistor cap, too.

Did you use OEM Honda parts for coil, points and condenser or aftermarket parts? Some aftermarket parts might be defective.  Erratic spark is generally due to either dirt/film on the ignition point contact faces, incorrect point gap or weak/failing condenser, assuming that the ignition coil is okay.

Did you see these?
