Testing a System 3-6 drop target bank

Steps

• Reset all the targets up and enter the switch test.
• Drop the targets one at a time: each should show its switch number once.
• When the last one drops, the bank-down (series) switch number should show.
• If it never shows, a target contact is bad, the chain is broken, or the bank is mis-wired.

Systems

• Williams System 3
• Williams System 4
• Williams System 6 / 6A
