Magnetic Pick-Up Assembly
The magnetic pick-up assemblies are located inside the distributor. All V8 engines use 2 pick-up coils, a start pick-up coil and a run pick-up coil. The dual pick-up coils operate as follows:
- Start Pick-Up Coil - Supplies a signal to SCC which will cause the spark plugs to fire at a fixed amount of advance during cranking only. This coil is permanently positioned in distributor and the amount of advance will be determined by distributor position. See Fig 1 .
- Run Pick-Up Coil - Once engine begins to run, the start pick- up coil signal is by-passed and the run pick-up coil supplies advance information to SCC. See Fig 1 . The SCC then modifies advance to reflect engine operating conditions reported by the other sensors.
