Magnetic Pick-Up Assembly

The magnetic pick-up assembly consists of 2 pick-up coils: start pick-up coil and run pick-up coil. Both are located in the distributor and 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. The SCC then modifies advance information to reflect other engine operating conditions supplied by other sensors. See Fig 1.
