IvanW 8 #1 Posted October 14, 2015 So my D180 has me baffled. I put a new coil on it and a new battery. When I turn the key to crank the engine, the coil sparks the plugs only once. Why is it not continuing to spark the plugs? Help! Share this post Link to post Share on other sites
mikekot3 92 #2 Posted October 14, 2015 Is there a operator presence switch in the seat? perhaps that is preventing startup? Share this post Link to post Share on other sites

gwest_ca-(File Mod) 10,515 #4 Posted October 14, 2015 Check for battery voltage at the coil (+) terminal with the key in the RUN position.Should still have battery voltage while running the starter motor.Check the coil (-) terminal voltage. When the points are closed you need 0 volts. When the points are open you need battery voltage. As you are running the starter the points should open and close giving you 0 volts and then battery voltage for every 2 turns of the crankshaft. The 0 volts will be for a longer period than the battery voltage period. Even a test light will work.Garry 1 Share this post Link to post Share on other sites
