Pick-Up Coil
- Connect vacuum pump to vacuum advance unit. If vacuum unit is inoperative, replace unit. Remove pick-up coil connector (Green and White wires) from electronic module. Connect ohmmeter leads to either pick-up coil lead and to distributor housing. See "A" in Fig 1. Set ohmmeter in middle scale. Operate vacuum advance throughout vacuum range. Reading should be infinite at all times.

- Connect ohmmeter leads to pick-up coil leads (Green and White wires shown in "B" of Fig 1). Again use middle scale of ohmmeter. Operate vacuum advance throughout vacuum range. Ohmmeter should read 500-1500 ohms in all advance positions. If either reading is not to specifications, replace pick-up coil.
