Kohler Bobcat 250EFI No Spark One Side.

admin

So, one cylinder quit firing.I used one of those spark testers that goes in line between the spark plug and the coil, and no spark.The coil on the other side tested good, so I put it in place of the no-spark coil, and no spark.Country-boy logic would indicate that the coil is not the problem.Sorta stumped.I guess the dead side isn't getting a signal, but I don't know where to start.Ideas?

Search Kohler  bobcat for manual. I'm not familiar with bobcat and only know enuf to keep stuf running long enuf to get paid. The last Kohler I worked on had a gap for stator windings/magnet.  Have tried different spark plug wire ?Start from the spark plug and work backwards.

Reply:Country boy logicSwap spark plug wires to determine if the wires are conducting the hi voltage coil, condenser buck. No?Johnibanzi (sp?) what model Kohler and horse power do you have?Last edited by Insaneride; 6 Hours Ago at 09:05 PM.
Reply:OK.So, it's the Miller Bobcat 250EFI built in 2015.It is equipped with a Kohler ECH 730 two-cylinder engine.One cylinder is not sparking.I removed the coil pack from the cylinder that is sparking and installed it on the cylinder that is not sparking.The result was that it still would not spark.I have determined to my own satisfaction that the coil pack itself is not the problem, and I am hoping that some wise soul can direct me further down the path toward getting this resolved.Thank you.
