Serial number is 5416647. I was doing a resistance test on the stator and did not take the wires of the switch box. I was getting continuity between the red and blue. I pulled the wires off and determined that the continuity was in the switch box. I tested the other box and it did not have continuity. 1. Should their be continuity between the red and blue post? 2. If not, could that cause weak spark on all six cylinders? Thanks in advance!

The switchbox and stator tests are explained on the CDIElectronics web site.

Yes but I have not found anything about red and blue on the switch box having continuity.

OK I had continuity between the blue and red on one box both ways and no continuity either way on the other box. I have ordered the DVA so I can properly diagnose it.
