Im am troubleshooting a zero spark problem and checked all of the obvious. I am now at the trigger. I did a volt meter test on all the wires of the trigger while they were off the switch plate leads. There was no reading on 4 of the 6 wires when I tried to crank. Does this mean anything or is this an incorrect way to test the trigger. How can I properly test the trigger. the manual is difficult to decifer. Thanks.
