 **PRECAUTION:​** If the engine happens to stop on the '​dwell'​ part of the cam position lobe, the GROUND thru points will keep power active on the coil if the RUN switch is ON. This means, if you turned the key on (or leave it on), with the RUN switch ON, without starting the engine, the coil will be in constant current saturation and will eventually 'burn up' the internal windings. **PRECAUTION:​** If the engine happens to stop on the '​dwell'​ part of the cam position lobe, the GROUND thru points will keep power active on the coil if the RUN switch is ON.
