    Pick-Up Coil

    Inspect/Test/Service/Replace

    • The pick-up coil wire leads can become grounded if their insulation wears off as the beaker plate moves with the vacuum advance unit. Inspect these leads carefully.
    Inspect pickup coil's wiring for damage and worn insulation.
    • Position these wires so they do not rub the breaker plate as it moves.
    • On some systems, the gap between the pickup and the reluctor must be checked and adjusted to manufacturer's specifications.
    • When checking the pickup coil, always check the distributor bushing for horizontal movement, which changes the pickup gap and may cause engine misfiring.
