Setting drop target reset coils to prevent metal fatigue

Steps

• Loosen the four screws holding the reset solenoid (or each of the two).
• Push the reset plunger fully in by hand.
• At the same time, slide the solenoid assembly back until the bank just latches.
• Tighten the screws. The coil should bottom out just before the bank link, with enough stroke left to reset reliably; fine-tune as needed.
