I am in the process of swapping in a new bridge rectifier board for my Harlem Globetrotters. The first thing I did was read the instructions and compare the wiring chart to the way my game was wired.
The instructions say that transformer lug one should be a yellow 18 gauge wire and transformer lug 5 should be a red 18 gauge wire. My game has a red 18 gauge wire on lug one and a yellow 18 gauge wire on lug 9.
This led me to pulling up the wiring diagram. I saw in the wiring diagram table for the power line connections that lugs one and three should be strapped together and lug five should be strapped to lug seven for 120 volts. The table shows lug one should be strapped to lug 3 and lug 9 strap to lug 11 for 115 volts, which is how my game is currently configured.
The line voltage at my house is right at 120. Should I go ahead and change it over to what the chart says for 120 volts by strapping lug one to lug 3 and strap lug 5 to lug 7? It also says for 120 volts to apply power to terminals one and five. Mine currently has power to terminals 1 and 9. If it's recommended to switch it to the 120 volts configuration, would I just move the yellow wire over to lug 5?
I wonder if this could be the reason the bridge rectifier that powers the feature lights went out multiple times?20220122_115837 (resized).jpg
