lordzoltron 0 #1 Posted April 22, 2015 Hey guys, I'm brand new to this forum and quite honsetly clueless about my Wheel Horse. I'm not getting any spark at all, and when I place a meter between the plug wire and the ground I get a constant 10 volts...anybody have any idea whats going on here? thanks.

gwest_ca-(File Mod) 11,393 #2 Posted April 22, 2015 Welcome to the forum. The good thing is it's just 10 volts. It should be about 15,000 volts and that would have destroyed your meter. What's the model and serial number of your tractor? What make is the engine and what are the numbers on the engine decal. We need to determine what type of ignition you have.

lordzoltron 0 #4 Posted April 25, 2015 (edited) Thx for responding Gary....Model is a 1-0140 I believe its a B 80 with a Kohler engine, maybe 8hp(not sure no tags on engine) . that 10 volts I'm getting is a constant when the ignition is off. Fried Coil??? no spark at all, grounds seem all good....serial# is 1015801 Edited April 25, 2015 by lordzoltron Share this post Link to post Share on other sites

gwest_ca-(File Mod) 11,393 #6 Posted April 26, 2015 If your coil looks like that it is battery ignition. Where are you getting the 10 volts? There should be battery voltage at the coil (+) terminal only when the key is in the RUN or START position. Should be 0 volts with the key OFF. Garry Share this post Link to post Share on other sites
lordzoltron 0 #7 Posted April 26, 2015 (edited) I get a steady 10V from the plug wire with ignition off... then drops to 0V when cranking... ignition makes more sense to me than a coil going bad just sitting through the winter. Was running find last time I shut it down in the fall. Edited April 26, 2015 by lordzoltron Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,393 #8 Posted April 26, 2015 Don't check the plug wire for voltage because if it happened to work correctly it would fry your meter. Check the coil (+) terminal voltage with key OFF - should be 0 volts. Check the coil (+) terminal voltage with the key in RUN position - should be 12 volts or battery voltage Check the coil (+) terminal voltage with the key in START position - should be 12 volts or battery voltage Remove spark plug so it is easier to turn the motor over by hand. Check the coil (-) terminal voltage as you turn the engine over. When the points are open you should see 12 volts or battery voltage Check the coil (-) terminal voltage as you turn the engine over. When the points are closed you should see 0 volts The points open and close once for every 2 turns of the crankshaft. Let us know what you find.
