    Trying to repair a circuit board for a rolling ball clock

    This clock has been running at least ten years or longer with the same wall wart. Putting a battery in the single slot doesn't power the clock on top. I also put in all four of the batteries (all new) but no reaction. I tested the black and red leads that run to the clock (with the batteries...

    Trying to repair a circuit board for a rolling ball clock

    So I have a multimeter and first attached the leads to the wall adapter to see what output was shown. Even though the switch is set to "6" it was putting out around 7.7. I then tried moving the switch to 4.5 and then the output was 6 volts. I left it at six (4.5 on the switch) and then...

    Trying to repair a circuit board for a rolling ball clock

    Tried with the pink circle but still no dice. Only two wires for the power adapter. Transistor numbers using colors you assigned Red S9014 C 202 Yellow S9014 C 202 Green S9014 C 202 Blue S9014 C 201 (only one that is C 201) The reflection on the middle one is making it...

    Trying to repair a circuit board for a rolling ball clock

    I'm blind apparently. I see the pink circle now. I will try the test again. Still did not rotate the arm at the top of the minute. I may just have to purchase a 120v 1rpm clock motor and replace the internal workings.

    Trying to repair a circuit board for a rolling ball clock

    Once the rotation stopped at the top of the minute (ran about 5 minutes this time) I then placed the jumper wire from point "A" to point "B" (I tried both sides of the solder blob) The arm still doesn't move at the top of the minute. Despite that should I still go ahead and resolder the "B"...

    Trying to repair a circuit board for a rolling ball clock

    The two wires are black but appear gray in the photos. The two yellow/orange wires go up to the reed switch. Normally if bypassed they can kick the motor into turning. Whenever the motor stops functioning, bypassing the reed switch has no effect. The two yellow wires connect to the micro...

    Trying to repair a circuit board for a rolling ball clock

    The clock on top shows both top and front facing display. The two wires on the side go down to the battery/dc plugin. I'll try and test the output of the adapter and get back with that. I could simply use batteries for the meantime to see if the same behavior happens. EDIT: Battery test will...

    Trying to repair a circuit board for a rolling ball clock

    No batteries attached. I am using a wall adapter to supply the 6 volt 100 amp input. I don't have another adapter to test with. There is a plug-in on the back of the unit for an adapter. I assume it is still getting power since the clock/counter at the top is still running.

    Trying to repair a circuit board for a rolling ball clock

    I didn't state the issue correctly. Whenever I place the wire across and the motor runs, I then remove the wire and the clock works correctly for about an hour. The reed switch is being triggered correctly and everything seems to be running as it should. After about an hour it suddenly stops...

    Trying to repair a circuit board for a rolling ball clock

    The two yellow wires come from the top (left in this picture) are the wires to the reed switch. The red and black wires from the top I assume are the positive and negative leads which go to the circuit board. The blue wire from the circuit board goes to the left side of the motor and a black...

    Trying to repair a circuit board for a rolling ball clock

    New images. Third image is where I tried first on the "green" side. First image is on the component side. Both contacts caused the motor to start up and continue to run for about an hour.

    Trying to repair a circuit board for a rolling ball clock

    Bypassing the magnetic reed switch does not cause the motor to run. I randomly tested various points because I don't know what I'm doing. I'll try to get better pictures posted.

    Trying to repair a circuit board for a rolling ball clock

    Noob trying to fix a small circuit board for a rolling ball clock. I have a rolling ball clock which stops working. The clock/counter at the top runs correctly but it doesn't turn the arm at the top of the minute. Bypassing the magnetic reed switch doesn't do anything but by chance I was...
