Kill switches on bikes and ATVs short out the HV, so when they are running there can easily be 200 volts on the switch. It may test fine with a dc ohm meter but not run because of corrosion, dirt, etc. So what I should say is you cannot reliably test a kill switch. I make and sell new CDis for Yamaha and have seen this several times when a new CDI does not fix a no spark because of this.
