What to do if Hirth Engine has no spark on one set of ignition?
- MMorgan FarleyAug 5, 2025
If your Hirth Engine has no spark on one set of ignition, start by checking for a bad connection, broken, or disconnected wires. You can also try the spark plugs that do work. Try exchanging the ignition wires that originate from the ignition module at the point of the coils, or where they exit the engine and attach to the ignition coils. If the same coil remains dead, the coil is likely defective. If the coil that was not firing before is now active, the problem might be in the CDI module or stator plate, so repair or replace the defective part. If the same side of ignition remains dead, the CDI box might be bad. If the opposite side of ignition that was not firing before is now active, the stator plate might be the problem; repair or replace it as needed.
