[AT] 6-volt distrubtor ignition

[Bigdog]

Kyle,
    Try cleaning and re-gapping the points.  They may be glazed over.  The current path for the coil primary would from the battery to the switch to the coil to the points to ground.  If you clean & gap points, crank the engine over with the coil secondary wire positioned close to the tractor frame.  If you have a spark there, the problem has to be in the cap / rotor area.  If you got a spark when you shorted the points it sure looks like the points are not making the circuit - either burned or glazed.

  Went to try and start my MM RTU last weekend and found I had no spark at the plugs.  I shorted across the points and I got a spark.  Where do I trace the potential problem after that?  I suppose the rotor and distributor cap could be potential problems - does the coil come in-line in the circuit after the points or before?

  The tractor has always been a good starter and runner until last weekend - it just suddenly has no juice at the plug.  Any ideas?

  Thank you,
