Detroit Diesel Troubleshooting Diagrams

The ignition coil assembly consists of the ignition coil and integral seal. This is serviced as an assembly, or the seal can be serviced separately. Before the coil can be installed into the engine, it is necessary to attach the boot, mounting screws, and O-rings onto the ignition coil assembly.

Series 60G genset engines use the coil over plug ignition system. This system consists of six coils, six ignition boots, mounting screws and seals, an igniter module, an igniter module bracket, an ignition coil harness, a ground strap, and six spark plugs. The coils mount in the rocker cover directly above the spark plugs. A coil cover mounts in the rocker cover which protects the coils and shields electromagnetic radiation (EMR) from the environment.
