I've got a bit of a head scratcher... maybe you guys have seen this before.
395xp, kill switch will not stop the engine. Replaced kill switch. New kill switch does not stop engine. Get out multimeter. Good continuity from blue wire to coil. Good continuity from black wire to ground. Determined that new kill switch is bad... either open circuit or sometimes very high resistance, 1.4 megohms+. Luckily, I saved the old switch, multimeter says it is GOOD. So, checked resistance from blue wire to ground bypassing the switch. Also very high resistance, again 1.4 megohms+. Resistance from Black wire ground point to engine cylinder is again high at 1.4 megohms+. Resistance from coil contact (blue wire to the engine) reads about 200 ohms.
Where would I look to find where the connection is broken or bad? Does that circuit for the coil grounding go through the AV springs, or ???
