Alge GAZ communications problems

Another issue that has appeared this season is the fact that the connections between the yellow and black banana plug sockets can break over time. The sockets are connected to the circuit board with bare wire jumpers. Over time and repeated usage the wire can break. Commonly the scoreboard will appear to be normal upon start up but it will just sit there on A L G E without doing anything else.

Remove the circuit board with 5.5 mm nut driver or carefully with needlenose pliers, and resolder the jumper wires. We twist some stranded wire along side to add a splint to help prevent this from happening again.

You can also input signal to the display using the 4 pole amphenol connector. Pin 2 is ground and Pin 4 (ground symbol) is signal.

In a real pinch you can break into the wires going to the 4 pin molex plug going into the main circuit board. Use an awl to pierce the insulation of the yellow signal wire and insert your signal wire. Do the same thing for your ground.

PST stocks replacement circuit boards for GAZc and GAZ 4 displays.

Also remember that each rotary dial position has a specific function. Sometimes the functions conflict. For example and display with the dial on 15 will appear to work but it is really displaying the running time since you plugged it into the timer. Program 15 is the standalone running time program that conflicts with Program 0 that the timer is sending out.

To review:

Program 0 = Simple default timing with any ALGE timing device, Split Second "ALGE" setting, etc.
Toggle in the middle for min:sec sec: 100ths, Up for Bib/Rank, Down for Hrs:min min: sec sec

Program 1-10 = Addressable lines. Such as 2 & 4 for dual timing with Split Second

Program 11 = Self test mode. Each digit counts down right to left with toggle in the middle.

Program 13 = Shift Left. Shows 1000ths with ALGE output.

Program 14= Countdown

Program 15= Count Up (marathon clock)
